%X 应用QUAL2K模型，采用试错法对沙溪沙县段进行水环境容量的计算，并根据排污现状，得出需要削减排污量的河段. 研究表明，从整个河段看，沙溪沙县段的剩余水环境容量仍有盈余，CODCr剩余环境容量为14 668.380 t·a-1，氨氮剩余环境容量为1 051.011 t·a-1，总磷剩余环境容量为131.163 t·a-1，但某些河段的允许排放污染物量需要削减.<br>In this study，the QUAL2K water quality model was applied to calculate the water environmental capacity(WEC) with the trial and error method in Shaxi River (reaches in Shaxian County). According to the current pollutant discharge and WEC research results，the reaches which needed reducing discharge pollutants were identified. The main conclusions were as follows: The WEC was surplus for the whole reach，the surplus WEC of CODCr was 14 668.380 t·a-1，the ammonia nitrogen was 1 051.011 t·a-1，and the total phosphorus was 131.163 t·a-1. The discharged pollutants in some reaches needed to be cut down
