摘    要:在流域生态系统管理研究综述的基础上,对湖泊一流域生态系统管理的概念进行了界定,对水环境管理、综合流域管理与流域生态系统管理之间的差异进行了对比分析。确定了生态系统生态学、流域生态学、生态系统健康和流域方法为湖泊.流域生态系统管理的理论基础,生态系统方法和流域分析为其方法学基础。在上述分析的基础上,提出了湖泊.流域生态系统管理的6个主要步骤:研究范围界定、基础信息收集与基本生态学问题的分析和评价、管理目标设定、系统综合、生态系统综合评价、适应性管理;识别出湖泊-流域生态系统管理中的3个关键问题:①生态系统管理中的不确定性和障碍分析;②流域土地利用变化对湖泊水质和生态系统的影响;③流域生态子系统与社会子系统的关联。

关 键 词:生态系统管理  湖泊  流域  生态系统方法  生态系统综合评价

Abstract:Lakes and their watersheds provide important habitat for human beings.In recent years,with the growing problem of lake eutrophication in China and other countries,the importance of integrated management of ecosystems,environmental resources,and social systems within the watershed have been highlighted.Studies have shown that lakes and their watersheds should be viewed as a holistic system from a management perspective.Based on surveys about watershed ecosystem management,management definitions and principles are presented in this paper.Further,the differences between traditional water environmental protection,integrated watershed management and watershed ecosystem management are analyzed.Ecosystem ecology,watershed ecology,ecosystem health and the watershed approach are considered to be the fundamental theories for lake-watershed ecosystem management(LWEM).Ecosystem approach and watershed analysis are taken as the methodological basis for LWEM.In light of previous studies on ecosystem management,a practical process for LWEM is given in this paper.It consists of six steps.The first is scoping of object,area and stakeholders.Second,fundamental data collection and analysis and primary judgment of ecological issues are performed.The third step is goal setting,including operational goals.Fourth,systems in the lake-watershed ecosystem are synthesized,including ecosystem dynamics modeling of lake and the watershed(EDMLW)and scenario analysis and assessment.Next,integrated assessment of the lake-watershed ecosystem,in which ecosystem health and integrity are taken as indictors for assessing ecosystem structure,is performed;ecosystem service is valued to reflect ecosystem function and ecological capacity is measured as a token of supporting capacity of the ecosystems.Adaptive management is the last step in the process,including the formulation of collaborative action and rules,optimal selection of actions and preferential sites,implementation and enforcement,and monitoring,evaluation and feedback.Three core issues are identified for LWEM;uncertainties and obstacles in the process,the effects of land use/cover change to the aquatic ecosystems,and the linkage between social and ecological systems.
Keywords:ecosystem management  lake  watershed  ecosystem approach  integrated ecosystem assessment
