城市供水行业是我国的基础性产业,因此发展城市供水行业就显得尤为重要。水是生命之源,是万物之本,同样水资源也是稀缺的,具有公益性,随着我国城市化进程的加快和水资源危机的加剧,我国现有的城市供水行业规制体制已经无法适应新形势的发展,城市供水行业面临着前所未有的挑战,对城市供水行业的政府规制改革势在必行。  相似文献

城市水务行业的建设和发展是提升城市现代化水平的重要因素,而供水价格形成机制的完善程度是其高质量发展的关键.笔者基于我国城市居民供水价格形成机制现状,总结和借鉴国外供水价格形成机制先进经验,针对我国供水企业运营效率偏低、供水价格难以评估、第一阶梯价格水量基数偏高、供水价格调整未起到节约用水作用、供水价格经营性与公益性特征...  相似文献

城市供水,作为城市居民饮用水的主要来源,其状况已受到社会各界的普遍关注。当前,城市供水的战略重点,从增加水量转向改善水质。目前,我国大多数的城市供水企业把提高水质的大量工作用于制水厂的净化处理工艺上,往往忽略了供水管网产生的水质污染问题上。因而产生了供水企业出厂水严格按照国家标准执行,而管网水却有不同程度污染的现象,出现浑浊、红水、铁锈、红线虫等,使供水单位声誉受到影响。  相似文献

正供水管网漏损率高是供水行业面临的难题,给行业发展造成了很大困扰,在很多地区和城市,由于管网老化、漏损严重,供水企业甚至出现了长期亏损的局面。目前,国内大、中、小城市的管网漏损率均处于较高水平。从住建部获悉,根据对408个城市的统计,我国城市公共供水系统(自来水)的管网漏损率平均达到21.5%~30%。因此,全国各城市都非常重视管网漏损率的控制工作,将控制管网漏损率作为衡量供水管网技术和运  相似文献

Water resources carrying capacity is a foundational topic in water resources security strategic study and the foundational measurement of water resources security. Water resources constrain the scale and quality of social and economic development in many water shortage cities and regions. Thus, the management via dynamic water resources prediction is a key for the overall city strategic planning. In this study, an integrated dynamic model of water consumption was developed using system dynamics (SD) and based on water resources carrying capacity (WRCC) theory.  相似文献

This article presents a literature review on the concept of sustainability applied to cities and a proposal for transforming a town in the south of Brazil into a sustainable town. Improvements in energy, sanitation, waste and water conditions, as well as food, clothing, education and jobs generation were considered to enhance the citizen's quality of life and environmental protection.  相似文献

In contrast to most research on the non-monetary quality of life, which relies on subjective indicators, we construct objective measures of the non-monetary quality of life using regression methods, for South Africa's cities. We also analyse the extent to which the various cities have been able to turn improvements in per capita incomes (monetary quality of life) into non-monetary quality of life – as reflected for instance in a better environment, higher literacy and longer lives. When monetary quality of life measures are used for South Africa's cities, the ranking in 2004 was led by Johannesburg, Tshwane, Ekurhuleni, Cape Town, Durban and Port Elizabeth. However when residuals from a regression of per capita income on (HDI) are used as a measure of non-monetary quality of life (i.e. the proportion of HDI not explained by variation in incomes), coastal cities tend to obtain generally higher rankings, with Cape Town ranked first, followed by Ekurhuleni, Durban, Port Elizabeth and then Johannesburg and Tshwane.  相似文献

珠江三角洲是我国人口、经济高度聚集的区域之一,环境问题凸显,城市空气质量备受关注。基于2002~2011年珠三角9城市空气污染指数,运用空间统计分析方法描述珠三角城市空气质量的时空分布特征,采用格兰杰因果检验探究珠三角地区城市间空气质量溢出特征,并结合灰色关联分析珠三角空气质量的影响因素。结果显示:珠三角2002~2011年空气质量有所好转,具有显著的季节性特征,冬季污染较严重,夏季污染较轻;空间上呈现出空气污染以广州为中心向四周递减的分布模式,并且存在城市间空气质量的相互影响效应,位于珠三角中部的广州和佛山的空气质量对东、南部的深圳和珠海空气质量产生影响;工业SO2排放量、人均绿地面积和城镇房屋施工面积是影响珠三角城市空气质量的主要因素。  相似文献

Today, for the first time in history, half the world’s people live in cities. This puts metropolitan areas to the test, especially in developing countries, where the greatest part of urban growth is occurring. In order to meet the new challenges linked to urbanization, today’s growing cities need appropriate metropolitan governance. The present paper wants to investigate this issue, through the definition of a general model of metropolitan governance, which can be adapted to every urbanization context according to its own specificities. Considerable emphasis will be given to concrete examples to test the consistency of our model. In particular, since water and sanitation supply is one of the key challenges affecting metropolitan areas, we will apply our model to urban water management. Furthermore, an important focus will be given to the contribution that Information and Communication Technologies can provide to the implementation of the model.  相似文献

从某种意义上说,世界城市和全球城市是一对既相关联又略有差别的概念。世界城市研究的是20世纪上半叶以来的世界顶尖城市,而全球城市主要研究20世纪下半叶以来的世界顶尖城市,特别看重的是全球化进程中的城市功能与地位。当代中国提出的中国名城和世界名城之说则强调城市的气质和特性,研究世界城市之林中具有品牌特色和地位的城市。我们需要利用名城思维来整合各种资源,找准城市的主题,需要站在全球的视野看名城品牌,从而打造全新的世界名城。  相似文献

“宜居之城”理念,既是城市化和后城市化时代城市转型升级的必然产物,也是提升城市核心竞争力的重要途径。实践证明,宜居城市的打造需要多方面的努力,而且必须依赖于城市自身的各种资源,其中水资源的作用不可小觑。本文以重庆为例,分析和探讨了江河水资源在构建“宜居之城”中的作用,并针对存在的问题提出了建议。  相似文献

Urban greenspaces harbouring many species in cities are vital planning objects for enhancing biodiversity. Seeking to optimise ecological values of urban greenspaces, this paper explores 1. Bird composition by feeding and foraging characteristics in urban greenspaces located in densely developed central districts of Taipei City; and 2. Important features of greenspaces and underlying built environments that influence bird abundance, species richness, and diversity. Results show that the majority of birds found in the study sites are omnivorous and ground foragers; whereas birds relying on water/wetland habitats for feeding and foraging are relatively small in population and species richness. This suggests water/wetland associated environments and birds might be negatively impacted by urbanisation. Secondly, bird richness and diversity increase in accordance with greenspace size, water area, and habitat heterogeneity, but little relationship is found with greenspace structure, such as greenspace shape, distance to nearest greenspaces, and proximity to source patches of mountains and rivers. Also, no significant influence is observed from development intensity, which is measured by NDBI, and building height at greenspace surroundings. According to this result, this study suggests conservation of large greenspaces as a priority strategy for enhancing urban biodiversity. The development of land should take its potential ecological value into account while assessing environmental impact. For enhancing habitat quality of existing urban greenspaces, creating water bodies and increasing habitat types can be effective methods. Yet current planning strategies to increase street greenery and to connect urban greenspaces with surrounding mountains and rivers might only benefit specific urban exploiters or adaptors and result in little overall effect on richness and diversity.

An introduction to a vast but uncompleted survey of world history, this article argues that the study of the changing relationships among cities, states and trust networks can help us understand key elements of the emergence of our modern world. Beginning in ancient Uruk in modern-day Iraq, roughly five thousand years ago, the essay defines each of its central categories: city, state and trust network. It poses four questions to be pursued throughout the rest of the study. What determines the degree of segregation or integration of cities and states? What determines the relative dominance of cities and states? What determines the extent of separation or integration between cities or states, on one side, and trust networks on the other? What difference do these variable configurations make to the quality of ordinary people’s lives?  相似文献

ABSTRACT

According to the United Nations data more than half of humanity lives today in the cities, but it is expected that in 2050 it could be almost 80% of the global population. That means a transformative role of cities at all levels in the coming decades. Participation and democracy in the twenty-first century must be promoted and practiced from the cities. A popular participation based on the observation, and also in an active participation within the management of the government can promote good governance where citizens can be empowered to achieve a higher level of democracy in our cities but also in our society. Currently therés an international standard on quality management in local government; ISO 18091:2014, it contains 39 indicators on public policies that local governments cannot stop attending. I would like to present in this article the success case of the Integral Citizen Observatory of Los Cabos (OCI Los Cabos) based on this international standard, as a model of smart citizens aware and competent. It has been such a good job that the incoming Mayor has included it in the actual Municipal Development Plan for Los Cabos 2015–2018, the diagnostic report data and the proposals of the Integral Citizen Observatory.  相似文献
