广东罗浮山生物资源和旅游资源永续利用的探讨

罗浮山是广东四大名山之一,是驰名中外风景秀丽的旅游胜地,也是广东省南亚热带常绿阔叶林及珍稀动植物的综合性自然保护区,有维管植物201科676属1168种,分别占广东维管植物的718%、411%、166%。罗浮山生物资源很丰富,有药用植物和油脂植物等,也有不少国家保护植物和保护动物,而且自秦汉以来就是我国著名的风景区。论文对罗浮山生物资源和旅游资源的永续利用提出了5点建议。     

西部地区经济发展与水环境质量的相关分析

认识经济发展与水环境污染的关系,以求西部地区经济与环境的协调发展。文章运用环境库兹涅茨理论和自回归分析模型,对1995～2004年我国西部地区人均GDP与废水排放量的分析,可知西部地区的人均GDP增加1%,则污水排放量增加0.582%,经济发展伴随着水环境质量的持续恶化,说明西部地区目前处于环境库兹涅茨曲线的左半部分。因此有必要加强对水环境的规制和治理,改善经济发展和水环境质量之间的这种两难关系。还表明自回归模型对于西部地区水环境质量的预测也是有效的。     

新型伞形罩烟气洗涤器的性能研究

针对中小型燃煤锅炉的粉尘和二氧化硫等有害气体的污染问题,开发出一种新型伞形罩烟气洗涤器。以粉煤灰、空气和水为物系,测试了伞形罩烟气洗涤器的压降(ΔP)、除尘效率和动力消耗。实验的入口气速为10～18m/s,含尘浓度为2～22g/m3,液气比(L/G)0～0.8L/m3。结果表明:伞形罩洗涤器的ΔP较小,在250～750Pa范围内;当L/G为0.2L/m3时,除尘效率达98.8%以上,动力消耗约0.06×10-3kW.h/m3(气体约216Pa),实现节能高效的目的。     

从生态环境角度论鄱阳湖区农业可持续发展

鄱阳湖区农业资源十分丰富，具有发展大农业的优越条件。本文通过对湖区农业生态环境的脆弱性分析，指出湖区农业的非良性循环特性，提出防洪、抗旱、治涝、血吸虫病治理等对策措施，为湖区农业可持续发展提供决策参考。     

宜宾市水资源保护与可持续发展问题的探讨

本文从近几年来宜宾市工业及生活废水等排放情况及水环境质量的监测资料，阐述了我市流域水污染状况与可持续发展面临的主要问题，提出了水资源保护对策，以促进社会经济可持续发展。     

四川水资源可持续利用与水质保护研究

四川水资源以河川径流为主，可利用率不高；水资源时空分布不均，径流的地区差异大；水能丰富，开发条件优越。水质污染日趋严重。在分析水质现状的基础上，针对水资源利用中存在的主要问题，提出了水资源可持续利用与水质保护的相应措施：以大型骨干水利工程建设为重点，改善水资源的时空分布；把建设全国能源基地与实现地方电气化相结合，因地制宜开发水能资源；以生态环境工程建设推动水质保护和水土保持；开源与节流并重，加强水资源的综合利用。

Ethics of Sustainable Development – a Study of Swedish Regulations for Genetically Modified Organisms

In spite of stricter provisions inthe new EU directive on deliberate release ofgenetically modified organisms (GMOs), criticsstill advocate a moratorium on permits forcultivation of GMOs. However, in an attempt tomeet concerns raised by the public, thedirective explicitly gives Member States thepossibility to take into consideration ethicalaspects of GMOs in the decision-making. Thisarticle investigates the potential effects ofsuch formulation by means of an empiricalanalysis of experiences gained the last yearsfrom similar Swedish regulations for GMOs,aiming at promoting sustainable development.The faulty implementation shown in the Swedishcase indicates that legal stipulations forethics as such have limited importance. It issuggested that public participation is animportant factor for successful implementationof the ethics of sustainable development.     

INTEGRATING HUMANS IN ECOSYSTEM MANAGEMENT USING MULTI‐CRITERIA DECISION MAKING1

ABSTRACT: The Ecosystem Management (EM) process belongs to the category of Multi‐Criteria Decision Making (MCDM) problems. It requires appropriate decision support systems (DSS) where “all interested people” would be involved in the decision making process. Environmental values critical to EM, such as the biological diversity, health, productivity and sustainability, have to be studied, and play an important role in modeling the ecosystem functions; human values and preferences also influence decision making. Public participation in decision and policy making is one of the elements that differentiate EM from the traditional methods of management. Here, a methodology is presented on how to quantify human preferences in EM decision making. The case study of the National Park of River Nestos Delta and Lakes Vistonida and Ismarida in Greece, presented as an application of this methodology, shows that the direct involvement of the public, the quantification of its preferences and the decision maker's attitude provide a strong tool to the EM decision making process. Public preferences have been given certain weights and three MCDM methods, namely, the Expected Utility Method, Compromise Programming and the Analytic Hierarchy Process, have been used to select alternative management solutions that lead to the best configuration of the ecosystem and are also socially acceptable.     

灾害旅游资源探讨

灾害经济学中的害利互变原理表明，灾害也有“利”的一面。它在给人类造成巨大损失的同时，也塑造了奇异独特的灾害旅游资源，其开发利用效用是其他旅游资源无法代替的。本文系统阐述了灾害旅游资源的基本属性、特性、类型及可持续开发利用的设想，以便使灾害旅游资源可以发挥更大的社会和经济效益。
