The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

Speeding up the environmental protection and construction is one of the major issues in ＂Greener Olympic Games＂ held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for ＂Greener Olympic Games＂ held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment.     

少数民族村寨生态旅游开发与旅游可持续发展探讨——以贵阳花溪镇山村旅游开发为例

少数民族村寨在开发旅游的同时,也带来了自然和文化生态环境的破坏,要使民族村寨旅游实现可持续发展,必须走生态旅游发展之路。本文针对贵阳花溪镇山村旅游开发中的问题,指出了民族村寨生态旅游开发的薄弱点,从将目前的大众旅游转型为生态旅游、加强游客管理、组织村民积极参与、完善生态旅游产品结构几方面对少数民族村寨生态旅游开发规划进行了探讨。     

长江流域的生态安全与对策研究

长江流域生态安全对中国可持续发展具有重要的战略意义。由于长江上游地区是水土流失的重灾区和主要的污染源,三峡工程的建设也使得长江流域上游地区生态环境的综合治理更显紧迫,因此维护长江流域生态安全的重点在于上游地区的综合治理,其关键是加大长江流域生态建设的投入。文章提出了要切实加强长江流域的统一管理,加强立法体系的建设,积极推进西部大开发战略和尽快建立绿色GDP核算体系等政策建议。     

民族地区经济可持续发展的障碍与对策探讨——以恩施土家族、苗族自治州为例

湖北省恩施州是全国30个少数民族自治州之一,属于国家西部大开发区域范围。实施经济可持续发展战略是该地区走出贫困现状的必然选择。加快制度创新,严格控制人口数量,努力提高人口素质,发展特色经济,调整和优化产业结构是实施可持续发展战略的基本对策。     

我国农业生态系统营养循环链的断裂与重建

完整的营养循环是农业生态系统健康、可持续发展的重要保障。我国传统农业属于环境友好型生态农业。农业生态系统的营养循环结构完整，持续健康、繁荣。但是，随着工业化、城市化、市场经济的发展以及农业耕作方式的转变，农业生态系统营养循环的结构遭到严重破坏，导致一系列资源、环境、经济与社会问题。通过秸秆还田以及城市生活废弃物（排泄物、厨房垃圾等）向农业生态系统的返还，重建农业生态系统完整的营养循环，是我国农业生态系统持续健康发展的必由之路。     

上海市生态可持续发展评价研究

本文利用生态足迹法对上海市1985～2004年的生态足迹和生态承载力进行了研究，结果表明上海市入均生态足迹和生态承载力分别由1985年的1．9340hm^2、0．1582hm^2逐年增加至2004年的3．0459hm^2、0．5805hm^2，一而同期的入均生态赤字也由1．7958hm^2上升到2．6656hm^2。同时计算了万元GDP生态足迹，并预测了2010年的入均生态足迹和生态承载力。最后得出，上海市入口对自然资源的利用逐年增加，目前已超出了自然生态系统的生态承载力范围，现有的发展模式是不可持续的。     

基于生态足迹模型的可持续性度量研究--以吉林省大安市为例

针对吉林省大安市发展现状和存在的严重生态环境问题,运用生态足迹模型,采用多源数据,首次对大安市生态环境的可持续发展状况进行了定量研究;在此基础上,运用相对指标法对可持续发展的量化结果进行分级。研究表明,2001年大安市的生态需求大于生态供给,生态呈现“供不应求”的局面,人均生态赤字为0.56hm2,处于弱不可持续发展状态。     

Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.      

中小企业产业集群与绿色物流战略发展研究

产业集群对中小企业和所在地区的发展提供了一定的发展环境。现代物流的迅速发展不仅推动了产业集群区经济的发展，而且对区域环境的保护和可持续性发展起到了一定的推动作用；认识产业集群区绿色物流，从政府和企业两个方面采取措施实施绿色物流，是中小企业可持续发展的保障之一。     

浅析物流信息化与资源节约型城市的可持续发展

21世纪是全球物流发展的时代,其中信息在物流中发挥重要的作用。全社会掀起物流信息化建设的热潮,资源节约型城市要抓住这一有利时机,充分利用有利信息来发展物流业,实现经济的转型,从而保证本地经济的持续、健康、稳定的发展。本文从分析物流信息化与资源节约型城市的可持续发展关系入手,指出目前其原型城市在物流信息化建设中存在的问题及形成的原因,最后提出合理的建议。
