三峡库区人口环境容量与环境移民安置选择

三峡库区人口环境容量是库区移民安置的基础,农村移民安置规划的核心是按照土地等资源对人口的承载力来适量安置移民。三峡库区自然条件恶劣,经济发展落后,土地及其后备资源短缺,农村移民环境容量有限,影响库区移民的就近消化。环境移民是人口外迁的一种基本形式,起源于资源匮乏、环境恶化、生活贫困等物质性原因。直接映示出移民与环境、资源、生产资料的对比关系和移民对客体的渴望水平。

Environmental Capacity of Population in the Three Gorges Area and Environmental Settlement

Emigration settlement is based on the environmental capacity of population in the Three Gorges Area. The project to settle emigrants is carried out according to land and other resources suitable to the needs of population. Bad natural conditions, backward economic development, poor land and other reserved resources limit the environmental capacity of population in the country, and accordingly affect emigration settlement nearby in this area. Environmental emigration is a very basic form to settle emigrants, and this form of emigration settlement is directly resulted from decreasing resources, worsening environment, poverty and other material factors. It reveals the contrastive relations among emigration, environment, resources and materials of production, and also shows the extent to which emigrants long for the object.
