基于生态—社会服务功能协调发展度的湖泊健康评价方法

摘要:
本文首先运用频度分析法构建湖泊生态系统健康评价指标体系;其次,应用变异系数法与信息熵权法相结合的组合赋权法计算指标权重;在此基础上提出了基于生态-社会服务功能协调发展度的湖泊生态系统健康评价方法,并给出从湖泊综合发展水平和湖泊协调发展度两方面度量湖泊生态系统健康水平的等级划分标准.应用此评价方法,以白洋淀生态系统为研究对象,开展其健康状况及协调发展状况的模型实证研究.结果显示:白洋淀生态系统综合发展水平处于不健康病态萎缩状态,湖泊协调发展度属于临界协调发展.该方法综合考虑了生态完整性和社会服务功能两个方面的协调性和发展性进行湖泊健康评价,从协调、发展的角度为湖泊管理建设提供建议.同时研究表明协调发展度湖泊健康评价法具有计算简单、适用性强的特点,同样适用于其他湖泊健康评价.

Abstract:
In this paper, the lake ecosystem health evaluation index system was established using the frequency analysis method. Then, the weights of the index were calculated by the Combination Assigning Method combined Variation Coefficient Method with the Information Entropy Weight Method. Finally, the evaluation method of the lake ecosystem health was proposed based on the coordinated development degree of ecological-social service function. In addition, the classification standard of the lake ecosystem health level was given out from the aspects of lake comprehensive development level and lake coordinated development degree. Based on this evaluation method, Lake Baiyangdian ecosystem was used as the research object to carry out the empirical study on the health status and the coordinated development degree. The results show that the comprehensive development level of Lake Baiyangdian ecosystem is in the state of unhealthy morbid state, and the coordinated development degree belongs to the critical coordinated development. This method takes the coordination and development of ecological integrity and social service function into consideration while evaluating lake health, and provides suggestions for lake management construction from the point view of coordination and development.
