试论生态文明建设中的环境保护

随着经济的发展，人们越来越清醒地认识到，以污染环境和破坏生态来换取一时经济繁荣的危害日益突出。正是这种清醒，推动人类文明进行着一场深刻的反思和变革，把追求人与自然的和谐相处，推上当今社会发展主旋律的位置，它预示着人类进入一个生态文明的新时代。生态文明是协调发展物质文明的保障者，是与时俱进的精神文明的塑造者，是日益完善的政治文明的体现者。因此，建设生态文明既是实现全面建设小康社会奋斗目标的内在需要，又是深入贯彻落实科学发展观的重要内容；建设生态文明，必须强化政策支撑，增加生态文明建设的内生动力；必须强化执法监督，增加生态文明建设的环保执行力；必须强化生态补偿能力，构建最具活力的绿色发展模式。     

SUSTAINABILITY AT THE LOCAL LEVEL: MANAGEMENT TOOLS AND MUNICIPAL TAX INCENTIVE MODEL

The implementation of sustainable development may seem a simple concept when written on paper. However to carry-out long term actions put forward by the Agenda 21 (AG21) at the local level represents one of the main challenges as municipal governments in general do not have the capacity to effectively implement the process. Regional environmental assessment (REA) has shown to be effective in supporting decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement sustainable actions. However this requires long-term investments of AG21 plans and projects. The allocation of regular and consistent financial resources is one of the main ingredients for the sustainable development process. But traditional plans and projects financed by national and/or international funds may not be sustainable in the long-term because they become dependent on external funding. Research demonstrate that innovative economic instruments such as ecotaxes represent a feasible alternative to sponsor local sustainability because taxes are collected permanently by the government and could be invested in continuous actions. Ecotaxes experiences have provided important reference to structure a municipal incentive model (MIM) to sponsor AG21’s environmental plans and projects on a long-term (permanent) basis. However sustainable development cannot be solely through economic investments. A comprehensive municipal environmental management scheme (MEMS) has been established to support the incentive model. The scheme seeks not only to improve local institutional framework but also incentive continuous participation of local stakeholders at all levels of society. Participatory events and the provision of incentives (educational and financial) are key to motivate society to protect the environment and support actively the sustainable development process as emphasised in the RIO-92 Conference.     

村级水资源的管理与利用研究--来自南方四个村的案例分析

农村水资源及其相关设施的改革需要更多了解村和户层次上的现实状况和机制安排。以避免改革扭曲和失败。通过对湖北和广西共四个村的村委会、关键知情人及120个农户的调查。在村和农户两个层次上描述水资源及其相关设施的管理与利用，尤其是在干旱年份村和户所采取的策略。并深入分析了农村村级水资源管理与利用的制度安排与问题。得出的结论是。追求水利管理效率的市场化改革需要考虑干旱的威胁，要有基于风险的制度设计和法律保障。     

DESIGN OF AN INDEX OF WATER QUALITY1

ABSTRACT: This paper describes the formulation of an Index of Water Quality to evaluate the level of pollution in fresh water. A Four-Round Delphi equation, using a panel of seven nationally recognized water scientists, was performed to ascertain the pollutants to be included in the index, the relationship between the quantity of these pollutants in the water and the resulting quality of the water, and the importance of each pollution variable to each water use as well as to overall pollution. A multiplicative index was used to bring the pollutants together into one system.     

Sustainability: a Dissent

Abstract:  Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchot-era conservation (and thus ignores the many lessons learned since then); it need not be linked to land, to the land's functioning, or to any ecological science; it need not include a moral component; it is consistent with the view of humans as all-powerful manipulators of the planet; and, in general, it is such a malleable term that its popularity provides only a facade of consensus. When sustainability is defined broadly to include the full range of economic and social aspirations, it poses the particular risk that ecological and biodiversity concerns will be cast aside in favor of more pressing human wants. Given these many defects, the conservation movement should discard the term in favor of a more alluring goal, attentive to nature and its ecological functioning. A sound goal would incorporate and distill the considerable ecological and moral wisdom accumulated since Pinchot's day while giving conservationists the rhetorical tools needed to defend the land against competing pressures. In our view, conservation would be well served by an updated variant of "land health," Aldo Leopold's ecologically grounded goal from the 1940s. Land health as an independent understanding should set the essential terms of how we live and enjoy the earth, providing the framework within which we pursue our many social and economic aims.     

Towards a smallholder hydrology for equitable and sustainable water management

Situations of water scarcity challenge sustainability and threaten small users' access to water. In response to this problem, there has been a search for a method of hydrological analysis that can better represent the needs of small water users. While this search is rooted in the debate favouring a more participatory and inclusive allocation of the resource, it also requires a new focus on smallholder hydrology that can confront the gaps and biases found in current hydrological practices in many countries. This article looks at past hydrological practices and also at results of recent studies, highlighting the perspective of smallholder irrigators in surface water planning in Zimbabwe, and groundwater planning in India. These case studies show that wider social forces, not always best science, drive hydrological practices. However, new frameworks focusing on the water user can emerge for more equitable and sustainable water management.     

区域排污权交易模型研究

本文在分析了排污权交易研究进展的基础上，指出区域污染权交易比传统的排污权交易意义更大，并提出排污权交易地区交叉补贴的设想：将发达地区的排污权交易所得向欠发达地区转移，以解决欠发达地区产业结构调整乏力以及对发达地区的二次污染和发达地区环境容量资源短缺问题。在不考虑交易成本的假设下，通过建立不同地区排污权交易模型以确定排污权交易总量及其交易价格以及交易所获净增纯收益等。太湖流域由于经济最为发达，环境问题十分突出，是目前我国最适宜率先进行区域排污权交易试点的地区。通过假定太湖流域无锡和常州两市进行排污权交易，并利用两市1991—2000年的环境统计资料等相关资料进行了验证。计算结果表明区域排污权交易不仅具有明显的经济和环境效益，而且也是协调环境区域矛盾的重要手段。因此，不同地区间进行排污权交易在我国具有重要意义，在太湖流域等经济发达地区收效尤其明显。

Co-ordination for disasters

This paper was prepared in 1978 on the basis of a review of sociological and anthropological fieldwork conducted up to that time. Although theoretical in presentation its conclusions are formulated in accordance with the author's own extensive observations of organizational response to natural disasters in developing countries, especially those having sudden onset. Practical implications for co-ordination agencies and pre-disaster training are drawn.     

省以下生态转移支付制度环境保护激励效应

现有文献认为生态转移支付具有基本公共服务均等化与提升地方生态环境质量双目标,而目标的多样性会影响地方财政转移支付资金效果及目标的实现。文章基于环保支出和农林水支出的中介与调节效应,对生态转移支付的生态环境目标进行了理论分析,利用2010—2018年甘肃、贵州、湖北及河南四省的199个县的面板数据进行实证检验。实证研究表明:在样本期内,生态转移支付促进了地方生态环境质量的提升,中介效应和调节效应模型的结果表明,中国地方生态转移支付资金对辖区环境保护效果中,环境保护支出起到部分中介效应,农林水支出不仅调节了生态转移支付的地方环境保护支出效果,而且调节了环境保护支出对地方环境质量的影响。因此,由于地方政府具有环境治理信息优势,省以下制度目标更能体现辖区生态需求,省对县生态转移支付制度会有效促进地方生态环境质量的改善,环保激励效应较为明显。同时,县级地方政府应该逐步摆脱"先污染后治理"的路径依赖,逐步转向经济与环境"双目标协同发展"模式。为了协同生态转移支付的双目标,"自下而上参与式决策"可以作为环境治理的有益补充,通过地方政府多元化实践改善环境质量。
