在对湖泊生态系统健康评估的研究的基础上，选用乌梁素海物理化学指标（SD、DO、COD、NH3-N、BOD、TN、TP）数据及生物指标（浮游植物数量、浮游动物数量、底栖动物生物量、水生植物覆盖度、浮游植物叶绿素a）数据等12项指标，利用指标体系法计算乌梁素海生态健康综合指数，结果表明：乌梁素海生态系统综合健康指数总体上呈现明显递减趋势，表明其系统健康状况整体呈下降趋势。该结果客观地反映了乌梁素海近些年来的生态系统的健康状况，为乌梁素海的管理提供了科学依据，为湖泊生态安全调查奠定了基础。

On the basis of the research to the lake ecosystem health assessment , twelve indicators including physical and chemical indicators（SD, DO, COD, NH3 -N, BOD, TN, TP） and biological indicators （planktonic number of plants, zooplankton, benthic biomass, coverage of aquatic plants, phytoplankton chlorophyll a） were measured to calculate ecological health of Lake composite index of Wuliangsuhai lake . the results showed that the trend of Wuliangsuhai ecosystem bealth index was signicant decreasing generally , the health state was integally decreasing . the results, objectively reflect the recent years of Lake ecosystem health status, It is a scientific basis on the management of Lake and Investigation of Ecological Security.
