广西西江干流治理工程对水源地水质的影响分析

Analysis of impact of Guangxi Xijiang River main stream harnessing project on water quality in water source area

以广西西江干流治理工程为例,采用二维稳态混合衰减水质预测模型计算主要污染物浓度分布,并利用ArcGIS软件中的克里金模型绘制污染物等值线图,将污染物浓度预测结果可视化,得出主要污染物影响范围,分析了工程施工和运行对饮用水水源地水质的影响,为相关涉水工程建设和水源地保护提供技术依据。

Taking Guangxi Xijiang River main stream harnessing project as example,two dimensional steady-state mixed attenuation water quality prediction model was used to calculate the concentration distribution of main pollutants,and pollutant contour map was drawn with the Kriging model of ArcGIS software,so as to visualized the pollutants concentration prediction results and identify the affected scope of main pollutants.The author also analyzed the impact of project construction and operation on the water quality in drinking water source area,which provide technical basis for construction of related water projects and water source area protection.
