2009-2018年江苏省太湖西岸主要入湖河道水质变化趋势

Water quality tendency of main inflow rivers entering the west bankof Taihu Lake in Jiangsu Province from 2009 to 2018

为了解太湖西岸主要入湖河流的水质变化趋势,选取陈东港、殷村港、太滆运河、大浦港、漕桥河5条主要入湖河流2009—2018年水质监测资料,通过氨氮、高锰酸盐指数、总磷和总氮质量浓度年际变化分析及季节性Kendall检验,分析5条主要入湖河流的水质变化趋势。

In order to understand the water quality tendency of the main inflow rivers entering the west bank of Taihu Lake,the water quality monitoring data of five main rivers entering the lake from 2009 to 2018 was selected,including Chendong River,Yincun River,Taige Canal,Dapu River and Caoqiao River,and the tendency of water quality of 5 inflow rivers was analyzed by inter-annual variation of concentration and seasonal Kendall test of ammonia nitrogen,permanganate index,total phosphorus and total nitrogen index.
