The concept of sustainable islands: cleaner production, industrial ecology and the network paradigm as preconditions for regional sustainable development

This paper introduces a bottom-up approach towards sustainability which is called the Island approach. The basic assumption of ‘Islands of Sustainability’ is that development towards sustainability can be introduced starting from small sustainable regions. An Island is an area where sustainability is reached locally. Key points to create a sustainable region are communication activities, such as exchange of matter, energy, information, culture, capital and persons within the regional network and with the environment. One of the main theses is that sustainability is linked to the complexity of the regional network. The intensity, the speed and the comprehensive of internal and external interactions, as well as the connectedness of the regional network, have to be changed in order to reach local sustainability.Relations between different approaches such as the Cleaner Production approach, the Industrial Ecology approach and the Island approach are investigated. It is assumed that a combination of these approaches will lead to sustainability, which might not be the case with one approach in isolation. All concepts are based on the new Network Paradigm, which is a reduction of the holistic world view. Cooperation on different hierarchical levels, from the interfirm level up to the interregional level, becomes an important part of behaviour. Networks, such as information networks or matter-flow networks, are introduced and become most important with regard to sustainability.     

区域农业持续性与持续发展研究

景观生态学属于宏观尺度生态空间研究范畴，它的理论核心集中表现为空间异质性和生态整体性两方面。持续性，包括农业景观持续性的最终目标在于人类与其环境的整体协调，即广义的人类生态整体性。持续性研究涉及广阔的地域空间，其目标的实现则有赖于空间途径。这一认识是将景观生态学应用于持续农业发展的理论出发点。     

工业生态学的演化与原理

在总结当前工业生态学（IE）主要研究成果的基础上，分析了IE的演化进程，阐述了IE的原理，并展望了研究方向。指出：IE是一门以提高工业过程中原料使用效率、降低废物排放弃为目的，研究工业系统及其与环境之间相互关系的应用生态学；其化过程经历了孕育、萌芽的提出第三个阶段；其主要研究对象是工业生态系统，而工业生态系统的主体是工业生产部门；工业生态系统的功能主要表现在工业生产过程中的物流、能流和信息流三个方面。     

从生态学观点看湖泊藻类控制的技术体系

富营养化水域中,引起湖泊水华和海洋赤潮的藻类疯长被称为“生态癌”。从生态学的观点分析了湖泊退化的原因,提出生态系统内物质循环的规模是否在自然环境条件所能支持的限度内是分析湖泊治理成效的判据,而将参与物质循环的过量物质从湖泊中移出则是湖泊治理技术的根本着眼点。文章还从生态学的视角架构了湖泊藻类控制的技术体系,并对每种技术在体系中的作用做了分析,由此提出了湖泊治理的技术路线。     

张家港市生态环境评价研究

从生态环境状况和生态安全2个方面对张家港市生态环境进行评价和研究,计算了生物丰度指数、植被覆盖指数、水网密度指数、土地退化指数、污染负荷指数等5个指标,计权确定该市生态环境质量指数为48.7,评价等级为一般;同时选择了资源安全评价、环境安全评价、生物安全评价和灾害安全评价等4个要素,确定该市生态系统安全指数为0.44。     

Marine shrimp aquaculture and natural resource degradation in Thailand

Rising demand for shrimp in the developed nations has helped to foster a dramatic growth in marine shrimp aquaculture, particularly in South America and South Asia. In Thailand, Marine shrimp aquaculture is now an important earmer of foreign exchange. The growth in Production has been achieved through the expansion of the culture area and the adoption of intensive production methods. The conversion of near-shore areas to shrimp culture, however, is proving to have many consequences that impinge on the environmental integrity of coastal areas. This paper reviews the development of Thailand's marine shrimp culture industry and examines the nature of the environmental impacts that are emerging. It then discusses the implications these have for rural poor and the long-term viability of the culture industry.
