Problems in population, manifested primarily as either "over" or "under" population, are ultimately related to the development of natural resources. Land is the most basic of natural resources. China's land mass is largely mountainous, with 56% of its more than 2000 counties, 1/3 of its population, 40% of its cultivated land and a majority of its forests, situated in mountainous regions. The quality and the distribution of the various kinds of land are complex and uneven. Although China is rich in forests, grazing, and arable land compared to the rest of the world, its 1 billion population makes the land a limited resource. The limitations of the land are also seen in soil erosion, soil that is increasingly turning into sand, and deforestation. Water resources are not considered scarce, yet compared to the rest of the world, it is limited. Its distribution is very uneven, with more water in the east and west, and less in the north and south. In the southwest mountainous border regions, for instance, water is abundant, but the population and arable land there is such that the demand for water is low. Moreover, droughts and heavy precipitation make the annual water supply unpredicatable. The demand for water becomes increasingly greater as agricultural production develops further, the population increases and as the cities continue to expand. living matter as a resource includes all the animal and plant life that is necessary for livelihood, but only forests and grasslands are discussed here. China's forests, if their use is not abused, can serve as a continuous supply for manufactured products. But its distribution is uneven and sparse. Population control will be ineffective if the forests are not replenished and developed. Grasslands are the primary source for animal products. The natural grasslands, found mainly in the north and west, are not as productive as that of other nations due to the nature of China's topography, the vagaries of climate, and deterioration. Energy, the source for fuel, includes such natural resources as coal, petroleum, natural gas, hydraulic, and solar power. China is among the world's richest in energy resources, yet the supply is sometimes insufficient when spread among 1 billion people.  相似文献

This bulletin examines the narrowing margin between global food production and population growth. Between 1950 and 1971, world grain production nearly doubled and per capita production increased 31%. During the 1970s, gains in output barely kept pace with population growth, consumption/person declined in sub-Saharan Africa and parts of Asia, food prices were volatile, and over 100 food deficit countries came to depend on the exportable surplus of North America, now the only major grain exporting region. The world fish catch levelled off in the early 1970s and beef production, still dependent mainly on grassland grazing, levelled off in the mid-1970s. With little new land left to plow, satisfying increased food demand now depends on sharp increases in yields on existing crop land. Worldwide, this effort is hampered by loss of topsoil and irrigated land, conversion of cropland to nonfarm uses, rising energy costs, inefficient agrarian structures, particularly in the Soviet Union, the falling yield response to chemical fertilizers in agriculturally advanced countries, and the emerging competition between food and agriculturally based energy crops. Green Revolution successes in some developing countries deomonstrate that, given the right inputs, 3rd world farmers can increase crop yields dramatically. Feeding the world's poor also requires more equitable income and food distribution, including a reduction in the proportion of grain and fish consumed indirectly as livestock products by the affluent. Most important in meeting food needs on a finite planet is braking population growth. The author concludes that every effort should be made to stabilize world production at abour 6 billion by 2020, rather than 10.5 billion by 2110, as is now projected by the UN.  相似文献

The general trend in the last several hundred years has been that the speed of growth in the food supply exceeds the speed of the population growth. For the time being, 2 major problems still exist. The 1st problem is that food production is still influenced by natural conditions. For example, abnormal weather conditions may cause regional food shortages. The 2nd problem is the imbalance of food consumption by the world population. This phenomenon exists between different social classes as well as between developed and developing countries. According to statistics released by the World Bank, 1 billion suffer from malnutrition today and most of them are in developing countries. In developed countries, about half of their increase in the food supply is for feed grains, and those countries follow the policy of reducing farm land for the purpose of maintaing stabl e grain prices. Up to the present time, grain prices have been unstable, and this has become a rather heavy economic burden for numerous developing countries. Many developing countries are trying to increase grain production by increasing their arable land and promoting their cultivating techniques. However, these countries are facing the problems of finding and adequate water supply, fertilizer, and pesticides. In addition, a rapid population growth in these countries has offset their endeavors in agriculture. In recent years, these counties have realized the necessity of birth control. The world population growth rate has decreased from 2% to about 1.7% in 1981. Birth control and an increase in the food supply will bring new hope to the world's problems of overpopulation and food supply.  相似文献

Depending on the different purposes of population surveys, different sample sizes are required for accurate results. Using statistical methods, sample sizes for different types of population surveys for the Chinese population are estimated. Thus, to insure at least 90% accuracy, a sample size of 830,000 is required for marriage and birth rates and a sample size of 7.8 million for population age distribution. For population surveys on age specific death rates, a sample size of 56.32 million is required for a 1-year retrospective study and a sample size of 11.26 million required for a 5-year retrospective study. In the past, certain population studies were undertaken with no consideration for sampling errors. Sample sizes for surveys on age specific death rates and population age distribution were too small, leading to results that did not represent the total population. On the other hand, sample sizes for marriage and birth conditions were too large, resulting in waste in manpower, materials, and time. Statistical calculations are given.  相似文献

Unlike cities in capitalistic societies our socialistic cities are publically owned, and the relationship between rural and urban areas is mutually supportive and beneficial. 2 types of calculations are required for successful urbanization: an estimate of the total labor required in the city and an estimate of total agricultural products required to support the cities. Disregard for these 2 factors and overpopulated cities will result in unemployment, decreased agricultural production, inflation, and a decreased living standard. A balance between cities and country is important, and therefore population urbanization should be well planned. Capitalistic urbanization of population is based on the principle of private ownership and competition--from unplanned concentration of population in big cities to malignant expansion to the final decline of inner cities. Their governments are forced to redistribute the urban population. The same problem of overpopulated cities in underdeveloped countries results from stagnant agricultural production. We should learn from their mistakes in developing our cities. There are 2 types of socialistic urbanization. Russia has lopsidedly emphasized urban development and ignored agricultural production. Romania, on the other hand, emphasized both labor force distribution and agricultural production. Their numerous small cities near rural areas decrease the difference between big cities and the country. In the past we failed to follow our direction of urbanization--control the size of big cities, reasonably develop mid-sized cities, and actively develop small cities--because of the great difference in living standards between urban and rural areas and the lack of urbanization plans. The concept of industrialization must be accompanied by the concept of population urbanization.  相似文献

A correct population policy is very crucial to the solution of the population problem, economic development, and social progress. The real situation in China now is a large population, a high rate of population growth, and low level of productivity. Facing this situation, China's population policy should include control of population growth in quantity, a promotion of population quality, and a match between population growth and social and economic development for the final realization of the Four Modernizations. In recent years, under the leadership of the National Committee on Family Planning, together with cooperation from various offices at the local level, a great change has taken place in China's population situation. The fertility rate has declined gradually, and late marriage, delayed births, and a reduced number of births have also become popular. A change in the age structure of the population has also slowed the pace of population growth. A reduction in the ratio of women of childbearing age is also helpful in the control of population growth, and the natural growth rate for the population has declined. This change shows that family planning is working in China and great results have been achieved. To come closer to the national goal of population control, practical work should be focused on rural areas. The rural population constitutes about 80% of total population and the fertility rate in rural areas is much higher than that of the cities. If population control can be achieved in the rural areas, the overall goal of population control for the country can then be achieved more easily.  相似文献

In 1949, the population distribution in China was characterized by the following distinct features. First, it was unbalanced, with high density in the eastern regions, in the plains, and in areas adjacent to railroads, river navigation routes and other transportation axes. Low population density was found in the western regions, mountainous regions, and areas far from transportation routes. Second, Hans were largest in number and distributed throughout the country, with major concentration in the eastern regions, while the minorities constituted about 10% of the total population and were distributed mainly in the far southwestern and northwestern areas. Third, over 89% of the 540 million of the population was distributed in rural areas while only about 10% in towns and cities, with high densities in some coastal cities. During the past 3 decades, the unbalanced nature of China's population has remained basically unchanged. This can be attributed to factors relating to natural conditions and resources, productivities, socioeconomic conditions, and technological development in different regions. In order to achieve a rational distribution of the Chinese population the following measures should be taken: 1) controlling the birth rate of the Hans and increasing the population of minorities; 2) moving the population of the dense areas to the border provinces in the western regions to develop their natural resources and to elevate the living standards; 3) modernizing the rural areas; 4) strictly controlling the industrial developments of large cities and their population growth; and 5) strictly restricting the unplanned migration of population to and from cities.  相似文献

An analysis of data from the 1946 census of the province of Hupei, China, is presented. Data are included on total population and population distribution, sex, age, marriage, education, employment, and place of origin. The demographic effects of the war against Japan are noted, and changes that have occurred over the 30 years since 1947 are considered. The author concludes that the demographic situation in Hupei in 1947 was representative of China as a whole.  相似文献

The objectives of current Chinese population policy are reviewed. The author notes that these involve a planned regulation of population to the point that the population remains stable and is of high quality. Included is a theoretical discussion on the mutual adaptation of material production and human reproduction, as well as a discussion on the means of production in determining trends in population development.  相似文献

There is a very close relationship between the population and the economy. The economy is the foundation for the existence and development of the population. Different socioeconomic patterns will determine population rules and population development, they have a strong influence on the social economy and the development of the entire society, and they may control the pace of social and economic development. In the last 30 years, excessive population growth has caused a great many difficulties for Socialist construction, overburdened agriculture, and created an imbalance in agricultural ecology. In order to understand the relationship between the development of the agricultural population and agricultural production, we have to understand to dominant position held by people in an agricultural ecology system. People have to control their own reproduction and match it with the productivity of the agricultural ecology system. Unrestrained population growth in the countryside is the main reason for an imbalance in China's agricultural ecology. Urgent action is needed to control the population growth in the rural areas, to fully utilized the available labor force, to promote the level of agricultural productivity, and to provide more employment opportunities. The final goal is to match China's huge agricultural human resources with its rich resources. investment should be encouraged to increase the wisdom and quality of the agricultural population. Both the quality and quantity of the agricultural labor force should also match development of agricultural productivity. In this way, a normal condition of agricultural ecology may be maintained.  相似文献

In the past 30 years, great changes have taken place in the reproduction pattern of the population in China. A historical pattern of a high birth rate and high death rate no longer exists. A new low birth rate and low death rate pattern has now become a reality. It is especially notable that China has realized this transition under the condition of a backward economy. Since 1949, the death rate has dropped rapidly because of advancements in medical care, a rise in the standard of living, and an improvement in public health. The change in fertility, however, is determined by the developing level of social productivity. As mankind has moved forward, population reproduction has gradually become a self-conscious activity. Fertility is increasingly determined by views on marriage and concepts of birth. China has successfully achieved a transition in fertility, and this has to be credited to China's progressive relations in social production and an excellent social system. In addition, practical efforts made by the political leadership, cooperation from the people, and popularization of ideological education on family planning have all contributed to a transition in China's fertility rate.  相似文献

The situation regarding the population of China over age 60 is reviewed. From 1953 to 1980 the aged population doubled in size, with the population in urban areas growing at a faster rate than in rural areas. The author notes that declining birth and mortality rates and longer life expectancy will cause the absolute number of the aged to increase. For China, each percentage point increase in the aged means an increase of 10 million aged people. As the ratio of the aged to the rest of the society becomes increasingly larger, China will become an aged society. Tables on age distribution and life expectancy are included.  相似文献

The social and historical development of population and education is subject to the restriction of the means of production. Although it is not the major factor in determing the direction of social development, it has a great impact on social progress and historical development. The scale and level of educational development are not only influenced by social and economic conditions but are also related to the scale of population growth and the number of people who receive an education. In studies of the relationship between the population and education, special attention should be given to the impact of population growth upon education as well as the everlasting influence of education upon the population structure and social mobility. Since 1949, because of a rapid population growth, the existing educational system in China has suffered severe damage and destruction. There have been an insufficient number of schools and a shortage of funds for education for quite some time, and the population growth has caused great pressure on education. The relationship between the population and education in a modern society is a rather complicated problem. As a country with a large population and a backward education, China needs to develop its education and promote its population quality in order that favorable conditions may be created for the overall development of Socialist modernization.  相似文献

Presented here is an analysis of some of the manually collected data from a 1% random sample of China's population taken on 7/1/87. 1)Population growth: The population grew 6.36% from 1982-87 to give a total population of 1,072,330,000. Even though the average annual growth rate of 1.24% during these years is slower than the growth rate of the 1950s and 1960s, this does not mean that China can be complacent about it. Due to China's large population base, every year its population increases by about 13,000,000, with serious implications for consumerism, education and labor. The natural rate of growth dropped during 1982-84, but by 1987, it had increased again to 1981 levels. If China is to limit its population to 1.25 billion by 2000, the average annual growth rate must remain below 1.23%, which is lower than the figures of recent years. 2) Sex differences: the population was 51.1% male and 48.9% female. 3) Age structure: 28.68% of the population were 14 years and younger; 65.86% were between 15-64 years; 5.46% were 65 years and older. The median age was 24.2 years. The percentage of the 0-14 year bracket dropped about 7.6% from 1953-87, while the 15-64 year olds increased 6.6% and the 65 years and older group increased 1%. On the surface, a 1% increase of the aged would not present a problem to China taken as a whole. However, when densely populated areas such as Shanghai are looked at, the situation demands immediate attention. 4) Ethnic groups: 92% of the population were Han. Minorities increased 5% annually between 1982-87 to comprise 8% of the population. This rapid growth among minorities is due in part to official permission for families to bear more than one child, and to better sanitary and medical attention. 6) Population distribution: 37.1% of the population lived in urban areas, as compared with 10% in 1949. By 1990 the urban population could reach 40%, creating serious social, economic and political pressure on cities.  相似文献

China has historically valued and promoted population growth. Throughout the centuries, China's population development was characterized by 4 trends: 1) High birth rate caused by: a patriarchical system and ethical philosophy of ancestor worship which required a continuous family line, plus a system of private ownership where land was the primary means of production; a political philosophy that encouraged births and punished the lack of offspring; and a social attitude that promoted early marriages. 2) High death rate caused by: civil wars and violent struggles for power; natural disasters; plague; and infanticide of female babies. 3) A relatively slow rate of population growth resulting from high birth and death rates. 4) A relatively sparse population and abundant land prior to the Qing Dynasty (1644-1911). With the establishment of a new China, basic changes occurred in the social system and the means of production. For 30 years (1949-1979), China enjoyed peace, higher educational and public health standards, and was free from disastrous natural calamities, a consequence of which was a higher birth rate and lower death rate. Concurrently the thinking was that "the more people the better," so that population grew at an alarming rate. From 1949 to 1979, China's population increased by 422,150,000, compared with its previous 2000 years in which the population had increased nearly 400,000,000. In 1965, the national birth rate was 38.06/1000 compared with 19.95/1000 in 1944 for the 6 largest cities. The death rate in 1938 was 28.2/1000, but by 1965 it had dropped to 9.55/1000. The rate of natural population growth in 1965 was 28.51/1000 compared with the highest rate in China's history of 1957/1000 durint the Eastern Huan Dynasty (25-189 A.D.). Unfortunately there has been no conscious policy to plan population growth along with economic growth, so that population grew uncontrolled and people had less land per person than at any other time in China's history. Thus, China now advocates 1 child per couple.  相似文献

Population is the basis of all social activites and social production. Population growth and development must have a definite means of subsistence to meet its cultural and material needs. The larger the population of a country, the greater is its demand for consumer goods and, likewise, the yield of its means of subsistence should be greater. Population brings about the unification of production and consumption. Furthermore, the ratio of population to the means of subsistence must be maintained at an appropriate level. Population growth must be slower then the growth of the means of subsistence in order to ensure continuous economic expansion and population increase. However, there are some people, notably Malthus, who believe that the balance between population growth and the means of subsistence should be equal. It is crucial to note differences between Marxist and Malthusian points of view. The basic outlook on the nature of the relationship between population and the means of subsistence is different. For Malthusians, it is a matter of the number of people and the quantity of the means of subsistence. For Marxists, the relationship is a historically determined social relationship. For Malthusians, population development is the primary force behind social development, i.e., the imbalance between population and the means of subsistence stems from social ills. Marxists differ from this in believing that population cannot be divorced from material production. Malthusians believe that population surplus derives from a population increase that is greater than an increase in the means of subsistence. Marxists believe a population surplus is also an historically determined social relationship. The Malthusian outlook for the future of population and the means of subsistence is pessimistic, whereas the Marxian view embodies the optimism of revolution.  相似文献
