TROPHIC STATE INDEX AND ITS CORRELATION WITH LAKE PARAMETERS
我国若干湖泊水库的营养状态指数TSI_c及其与各参数的关系

Based on various trophic state characters of 24 lakes in China, the trophic state indexes(TSIc)and its correlations with lake parameters are presented. Comparison between TSIC and TSIm of the lakes shows that in order to describe the trophic states of these lakes,TSIc is more suitable than TSIm for the linear response between biomass and trophic salt in lake water. A comprehensiv6 trophic state index weighted upon correlation relationship of various parameters is also suggested. The trophic state can then be described with a comprehensive state form.
