高州水库2016-2020年水质评价分析

Analysis of Water Quality Changes of Gaozhou Reservoir from 2016 to 2020

运用主成分分析、卡尔森营养状态指数(TSl m)、营养状态指数(EI)等方法对高州水库的良德库区、石骨库区重要监测断面近5年水质进行评价。结果显示:高州水库长期处于中营养、轻度富营养级别,存在水华突发风险。

The Liangde area and Shigu area of Gaozhou Reservoir were analyzed and evaluated.The principal component analysis,Carlson trophic state index(TSl m),trophic state index(EI)and other methods were used to analyze and evaluate the water quality changes of the two important monitoring sections of Gaozhou Reservoir in recent five years.The results show that Liangde area and Shigu area have been in the middle and light eutrophication level for a long time,and there is a risk of water bloom.
