Abstract: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.
