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。     

Researching Preferences,Valuation and Hypothetical Bias

A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation (CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private good but may purchase information about their own value (researching preferences). The second component is that there is a probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect on the winning bid.      

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。
