摘要
为掌握浊漳河流域水环境状况,进一步探索浊漳河流域水污染治理的对策,依据2016-2018年浊漳河流域15个样点的实测数据,采用聚类分析法对浊漳河流域总磷、总氮变化特征进行分析.结果显示浊漳河流域总磷、总氮的变化规律为:在时间尺度上有明显的季节性差异,TP浓度体现在枯水期>丰水期>平水期,TN浓度总体上枯水期>平水期>丰水期;年际间均呈直线下降式变化.从空间聚类结果看,流域水质状况与流域内污染源具有明显相吻合的空间分布特征,浊漳南源高于干流及其他两个支流.
In order to master the water environment condition of Zhuozhang River basin and further explore the countermeasures to deal with water pollution of Zhuozhang River,According to the actual measurement data of 15 sites along Zhuozhang River basin from 2016 to 2018,the paper analyzes the features of the changing of the total phosphorus and total nitrogen of Zhuozhang River by cluster analysis. The results show that there are obvious seasonal differences,the concentration of total phosphorus (TP)in Zhuozhang River is drought season>flood season >normal season. the concentration of total nitrogen (TN)in Zhuozhang River is drought season>normal season>flood season;and the data decreases linearly year by year. From the result of space cluster analysis,the water condition of the river basin is obviously in accordance with the pollutant resources,and the southern source of Zhuozhang River is higher than the master stream and other two tributaries.
