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.
