在对杞麓湖近20年来的水生态状况进行调查研究的基础上，以20世纪80年代初杞麓湖的水质和水生态系统数据为本底值，运用评估模型对杞麓湖1994—2013年湖泊水生态系统健康状况进行了评估。结果表明：杞麓湖水生态系统健康多年总体处于不稳定状态，20世纪70年代末至80年代初，水生态系统健康状况为“很好”；1994—2000年，水生态系统健康综合指数显著下降，处于较差和中等之间，水环境在该时期已受到明显污染；2001—2010年，水生态系统健康综合指数有所提高，处于中等和好之间，水环境状态平稳；2010年以后，由于多年持续干旱等原因，水生态系统健康综合指数明显下降，变为较差水平。

Based on the data of aquatic ecosystem of Qilu Lake in recent 20 years,an evaluation model was adopt-ed to assess the health changes of the lake during 1994 to 2013 using the data of water quality and aquatic ecosys-tem of Qilu Lake in the 1980s as the background value.The evaluation results showed that the aquatic ecosystem health of the lake was,as a whole,in a state of flux.The aquatic ecosystem was very healthy in the late 1970s and the early 1980s.However the composite index,which was between inferior and medium,dropped greatly during 1994-2000 when the water environment had been seriously polluted.The health of aquatic ecosystem became be-tween medium and good as the composite index increased during 2001 -2010 when the water environment kept steady.But a marked drop of the composite index in the inferior occurred due to a prolonged drought after 2010.
