摘要
The lake eutrophication is one of the most important problems in water environment of our country,which has been paid more and more attentions.Because of the special surroundings and the pollution of around the area recent years,Baiyangdian has on the serious eutrophication status.This paper use the methods such as grading method,trophic state index,genetic algorithms,grey cluster set to assess eutrophication in Baiyangdian.The result showed that,trophic state index and genetic algorithms reflect the various sections of the eutrophication level,but grading method and gray cluster set can improve on level division and weight choosing.
