Abstract
The current situation of the early spring eutrophication of Guanyin lake in Suining was researched based on the investigation data in 2016,the cause of the early spring eutrophication was analyzed through the change tendency for the past few years.The results showed that Guanyin lake water quality in spring was lightly eutrophicated,and the eutrophication of the right bank was lighter than the left bank,Peridiniopsis sp.was the absolute dominant species of phytoplankton.The trend of the early spring eutrophication of Guanyin lake has been becoming worse,the polluted water containing abundant nutritive salt flows into Guanyin lake and suitable climate in every early spring were the internal and external factors.The survival characteristics of phytoplankton and the rapid development of town speed up the lake eutrophication.Finally,four measures were proposed according to the current situation and tendency of the early spring eutrophication of Guanyin lake,in order to provide the reference for the management of Guanyin lake.关键词
