Yang Gao, Yong Cao, Zhen Zhao, Cong Jun Sun

Abstract

Basing on water quality and aquatic ecological data of 142 lakes in eastern region of China, the article selected causal variable (TN, TP, CODMn) and response variable (Chl-a, SD), used Comprehensive Trophic Level Indexes (TLI) classification method and got the eutrophication control standards of five factors. The result showed that the eutrophication control standards were in excess of values of III water standard in GB3838-2002. The result could provide scientific conference for lake eutrophication control standard.
