摘　　要：为支撑博斯腾湖未来保护工作,需认知博斯腾湖近20年的生态健康状况,在对博斯腾湖大湖湖区水质状况调查基础上,适当选取系统评价指标,以1991年水质指标为本底值,运用熵权法建立湖泊生态健康评价模型,计算生态系统健康综合指数,并对博斯腾湖大湖湖区近20年来的健康状况进行评价.结果表明,1997、1998及2005年的水体综合状况略好于其他年份,属较好水平;而1992、1993、2003及2008年的水体综合状况则低于其他年份,属较差水平.In order to provide basic insistence for the protection of Bostenhu Lake, it is necessary to know the status of ecological health of this lake. From the investigation of water quality in the Open Water Region of Bostenhu Lake, several different indices of ecological health were selected and a synthetic assessment model based on entropy weight was established. Water quality data of Bosten Lake in 1991 was selected as background values. The health of the Open Water Region of Bostenhu Lake during recent 20 years was assessed by the model and the ecological health comprehensive index （EHCI）. The results showed that the water health states in 1997, 1998 and 2005 were better than the other years. In contrast, the states in 1992, 1993, 2003 and 2008 were worse.
