郁江干流百色市辖区河段水质状况分析

Analysis of water quality for the main stream of Yujiang River in the area of Baise City

通过对百色辖区内郁江干流7个监测断面的水体质量状况进行变化趋势分析,并对部分超标断面进行原因调查,结果显示,郁江干流水质状况总体良好,但部分河段受上游水利工程的影响溶解氧浓度时有超标,部分河段受水产养殖影响出现总磷、五日生化需氧量超标的情况。

Analysis was made on the water quality change trend of seven monitoring sections for the main stream of Yujiang River in the area of Baise City.The causes were investigated for some sections exceeding standard.The re⁃sults demonstrate the water quality of the main stream of Yujiang River is generally good;the concentration of dis⁃solved oxygen in some river sections exceeded the standard sometimes due to the influence of the upstream hydrau⁃lic project;the total phosphorus and BODS in some river sections exceeded the standard due to the impact of aqua⁃culture.
