流域生态学与太湖流域防洪、治污及可持续发展

Watershed Ecology, Flood Disaster Control, Water Pollution Control and Sustainable Development in Taihu Basin

在评述流域生态学中的水文、湖沼、生态系统、景观、生态经济和生态管理等主要研究内容和复合生态系统、河流连续统、生态交错带、等级系统、格局 -尺度 -过程、信息系统等概念理论以及流域自然过程、生物功能、系统结构、生态环境、流域生态管理等流域生态学热点问题的基础上 ,总结分析了太湖流域防洪、治污及可持续发展与流域生态学的关系 ,指出流域生态学在太湖流域的流域开发、环境治理、区域可持续发展等实践方面起着越来越重要的指导作用 ,有必要开展深入研究 .

Watershed ecology is an intersect discipline of hydrology, limnology, ecosystem ecology, landscape ecology, eco economics and eco management. Because of the watershed ecology's significance to watershed sustainable development, people attach importance to it increasingly. About watershed ecology, we should pay more attention to these theories and concepts as follows: society economy nature muti ecosystem, river continuum concept, ecotone theory, hierarchy theory, pattern process scale, and watershed information system. Now, the trends of watershed ecology concentrates on five points which are watershed physical process, bio service, structure and function of watershed ecosystem, watershed environment and watershed management. In East China, there is an important region, which is Taihu Lake basin. 10 percent of Chinese GNP comes from this 0.4 percent of Chinese territory. But frequent flood disaster and increasing water pollution confront regional sustainable development. Based on the deliberation watershed ecology, the significance of watershed ecology to flood disaster control, water pollution control and sustainable development in Taihu basin are discussed in this paper. It is suggested that the study and application of watershed ecology should be an effective approach to solve those problems, and that it is necessary to deepen the research.
