摘　　要：以沱江支流阳化河为例,采用纵向一维水质模型计算流域水环境容量,分析得到COD、NH_(3)-N、TP的水环境容量分别为-1204.9、148.1、-134.6t/a,并进一步分解至流域内各县(市、区),确定乐至县COD、NH_(3)-N、TP环境容量均为负,雁江TP环境容量为负,金堂、中江、简阳COD和TP环境容量为负。研究成果可为区域水污染防治、水体达标提供技术支撑。Taking the Yanghua River, a tributary of the Tuojiang River, as an example, a longitudinal one-dimensional water quality model is used to calculate the water environmental capacity of the basin. The analysis shows that the water environmental capacities of COD, NH_(3)-N, and TP are-1204.9 t/a, 148.1 t/a, and-134.6 t/a, respectively, and further decompose to the counties(cities, districts) in the basin, and confirm that the environmental capacity of COD, NH_(3)-N, and TP in Lezhi County are all negative, the environmental capacity of Yanjiang TP is negative, and the COD and TP of Jintang, Zhongjiang and Jianyang is negative. The research results can provide technical support for regional water pollution prevention and control and water body compliance.
