摘　　要：以沱江流域资阳段为研究对象,在进行水功能区划的基础上,确定4个容量计算单元及7个容量计算子单元,运用一维水质模型计算水环境容量,以便为资阳市工业规划制定和水污染治理提供依据。经计算分析,沱江流域资阳段COD环境容量为28 270.17 t/a,NH3-N环境容量为1225.67 t/a;COD和NH3-N环境容量均主要分配在沱江干流,而沱江干流上游COD及NH3-N环境容量又明显高于干流下游环境容量。Based on the Ziyang Section of Tuojiang River Basin in the water function zoning four units and seven sub-units have been determined. Applying one-dimensional water quality model to calculate the water environmental capacity can provide evidence for making industrial planning and water pollution control. The results showed that the COD and NH3-N environmental capacities of the Ziyang section in Tuojiang River Basin were 28 270. 17 t/a and 1 225.67 t/a respectively. The environmental capacity of COD and NH3-N were mainly assigned in the main stream, and the environmental capacity of upstream was higher than that of the down stream.
