摘要
目前我国的河流富营养化是水污染主要的问题之一,为了进一步研究河流富营养化水质生态恢复前后营养盐的动态变化,本文以樟江为例,分析了2018~2020年期间4个监测点的水质数据。数据的结果表明樟江水体营养盐具有明显的年际和季节性的变化特征。为了恢复樟江水质的清水的状态,需要对流域内的农业污染源进行相应的管控措施。
At present,river eutrophication in China is one of the main problems of water pollution.In order to further study the dynamic changes of nutrients before and after ecological restoration of river eutrophication water quality,this paper takes Zhangjiang as an example.The water quality data of four monitoring points during 2018-2020 are analyzed.The results show that the nutrient salt of Zhangjiang River has obvious interannual and seasonal characteristics.In order to restore the water quality of Zhangjiang River,it is necessary to control the agricultural pollution sources in the basin.
