- 摘要:
- 湖泊生态系统健康评价是湖泊生态系统科学管理和生态恢复的前提和基础。熵权综合健康指数法评价湖泊生态系统健康状况的主要步骤有：建立评价指标体系；计算各指标的归一化值；确定各指标的熵权；计算湖泊生态系统熵权综合健康指数。并以滇池为例验证该方法的可靠性和实用性。该方法可用于湖泊不同时空健康状况的对比，得出湖泊生态系统的演替趋势，为湖泊生态系统的管理、保护和生态恢复提供依据，从而促进湖泊水资源的可持续利用，最终实现湖泊生态系统的健康发展。
- Abstract:
- Assessment of ecosystem health is the premise and base of scientific management and ecological restoration for lake.The primary steps of entropy weight comprehensive health index method contains establishing assessment index system, calculating unitary value of each index, determining entropy weight of each index and calculating entropy weight comprehensive health index of lake ecosystem.The application of this method in Lake Dianchi is given as an example, which validates the method is reliable and applied.This method can be used to compare health status of different time and space and to get the succession trend for lake ecosystem in order to provide basis for management, protection and ecological restoration.Accordingly, water resources of lake can be sustainably used and healthy development of lake ecosystem can be realized.
