太湖不同湖区生态系统健康评价方法研究

Abstract

Abstract: An attempt to apply exergy（Ex）,structural exergy(Ex_st),ecological buffer capacity（（|β|））and trophic state index(I_ts)to the assessment of lake ecosystem health was presented.It was obvious that there were different ecosystem health conditions in different areas of the Taihu Lake.A standard and a comprehensive health index(I_Ex)for evaluating ecosystem health of a shallow eutrophic lake were given.This method were tested in the Taihu Lake from 2002 to 2003.The results indicate that the comprehensive health index and criteria were applicable to evaluating ecosystem health in different areas of the Taihu Lake.

Key words: ecosystem health, assessment, indicator, Taihu Lake
