The road towards sustainable rural development: issues of theory,policy and research practice

Developing a more widespread diffusion of sustainable agricultural practices as part of progressing rural sustainable development is being hampered by different modes of environmental social thought. This introduction to this special issue on ‘Reconstituting of nature through rural development practices’ argues for a realignment of social theory and empirical practice in considering the real potentiality of alternative and emergent rural development cases. The social science of agro-ecology is introduced as an initial framework within which to assess such alternatives and emerging tendencies. Copyright © 2001 John Wiley & Sons, Ltd.     

Post-Fordist transformation,the sustainability concept and social relations with nature: a case study of the Hamburg region

Following the United Nations Conference on Environment and Development, the concept of sustainability in general and of urban sustainability in particular has become increasingly significant in the course of the 1990s. Even if the environmental problems of cities are far from being solved, one can interpret this development as a change in the relationship between society and nature on both a discursive and a material level. At the same time the transition from Fordism to post-Fordism has given rise to new forms of urban entrepreneurialism, with an absolute priority to economic competitiveness on the one hand and sharpened social conflicts on the other. Looking at the case of the Hamburg region, the article discusses the interaction of these processes. Contrary to the understanding of sustainability as a broadly accepted policy goal it conceptualizes sustainability as a terrain of conflict. As such, we will argue, the sustainability concept and the underlying change in social relations with nature contribute to containing the contradictions of capitalist societalization, which in the transition to post-Fordism have become more visible again.

离子膜烧碱工程环境风险评价与防范措施

近年来,全国各地有毒气体泄漏、火灾爆炸等事故时有发生。人们逐渐认识并越来越关心重大的突发性事故造成的环境问题,同时也加快了人们对化工建设项目环境风险评价的步伐,使我国防治环境风险的工作进入高潮。本文以滨州一离子膜烧碱项目为例,从风险识别、风险源项分析、风险计算、风险预测等方面对项目存在的风险进行环境影响评价,并提出相应的防治措施,以降低其对人类健康和环境的危害。     

Implicit beliefs about self and nature: Evidence from an IAT game

Recent psychological research has examined the beliefs that individuals hold about their relationship with the natural world. This article builds on the previous literature on connectedness with nature and we introduce a new game version of the Implicit Association Test (IAT), known as FlexiTwins. The game is intended to facilitate research using the IAT and provides a flexible platform for measuring implicit associations. In this paper, we report three studies in which we use the game to measure self-nature associations. Study 1 reports the development and validation of FlexiTwins with a college sample. Study 2 further validates the game using a known-groups sample of environmental activists. Finally, Study 3 examines the implicit connectedness of a sample of 30 grade school children. Across all three studies, we find good evidence for reliability, as well as theoretically meaningful results.     

Measuring love and care for nature

This study aimed to develop a psychometrically sound measure of the construct of love and deep caring for nature as an expression of people’s personal and explicitly emotional relationship with nature. Expert opinion and pre-pilot surveys were employed for refinement of the item pool, and a sample of 307 university students was used in a major pilot study aiming to further purify scale items. A field trial was conducted using a sample of 261 tourists at leisure with nature. The final 15-item Love and Care for Nature (LCN) scale is differentiated from established measures of similar constructs, and demonstrates high internal consistency and sound validity. This research extends the psychological frameworks of environmental altruism, and has also taken the philosophical concept of biophilia, as love for nature, into the operational realm by making it perceptible and measurable.     

塔里木河下游工程输水后的生态效益分析

以塔里木河下游为研究区域,分析了生态输水工程实施以来该区地下水埋深、水质、植被生长状况的不同响应程度。研究表明:生态输水工程使得原本较低的地下水位在一段时间内得到抬升,局部生态环境得到改善,尤其在输水中期(2003-2005年),植被物种组成发生变化,物种多样性增加,植被盖度提高,地下水水质有所好转;但2007年以后,尤其是2008年,随着输水的间断,下游地下水位开始回落,草本植物物种数量又开始减少,因此,生态输水工程必须持续进行才能真正挽救塔里木河下游生态环境。     

关于建设项目对自然保护区生态影响专题评价的思考

建立自然保护区对保护生物圈及生物多样性具有十分重要的作用。我国已建立各种类型、不同级别的自然保护区2000多处。随着我国社会经济的发展,全国各地各类开发建设项目涌现,一些开发建设项目与自然保护区的保护要求发生矛盾。使开发建设项目避免或最大程度地减少对自然保护区的不利影响,做到保护与建设的双赢,是编写开发建设项目环境影响评价文件的一个重要内容。涉及自然保护区的开发建设项目一般要求编制对自然保护区影响的专题报告,本文根据工作实践,提出编制该类专题报告的主要内容及应注意的问题。     

我国应急预案体系现状及展望——以上海为例

应急预案在自然灾害等突发事件发生时可以起到迅速反应的作用,因此成为突发事件应急管理中重要的一环。我国的应急预案体系已经基本建成,但还存在着预案格式雷同、脱离部门实际、分级体系科学性和可操作性不强、不同预案间接洽性不够、预案建设数量质量不够、缺乏后续管理等种种问题。分析了国内应急预案体系的现状,并探讨了对应急预案体系的改进方法。     

风险矩阵法在危险有害因素分级中的应用

为减少风险分级时产生的风险结,采用Borda序值法改进原有的风险矩阵法。改进后的风险矩阵法通过计算Borda数,依据Borda数的大小对风险进行排序,使得风险等级数量大量增加,从而减少风险矩阵中风险结的数量。将该方法应用于某烧碱装置危险有害因素分级管理,对生产过程中的9种主要危险有害因素进行排序,得出它们可以分为6级,而应用原始的风险矩阵法得到的分级数为3级。然后,依据分级结果提出针对性的安全对策措施。
