根据东风西沙水库取水口水域枯水期、平水期以及北支河道丰水期、枯水期的水质监测资料,采用水质监测分析与模型计算相结合的方法,系统分析北支咸潮倒灌对崇明岛东风西沙水库取水口水质的影响.结果表明:徐六泾取水口水域的水质明显好于北支,即使在特枯年的枯水期,北支咸潮倒灌进入取水口水域产生的污染物质量浓度最大增量不高于0畅22 mg/L. DO、COD、BOD5、NH3-N、TP、TN、FN、油类、Hg 9个项目中,除 TP 由Ⅲ类降低为Ⅳ类外,其他指标类别基本不变,均优于Ⅲ类.

Based on water quality monitoring data from water intake areas of the Dongfengxisha Reservoir in dry and normal seasons and the north branch in wet and dry seasons , the water quality monitoring analysis method and model calculation were combined to systematically analyze the effects of salinity intrusion of the north branch on the water quality of the water intake areas of the Dongfengxisha Reservoir on Chongming Island .The results show that the water quality of the Xuliujing water intake area was significantly better than that of the north branch .Even in the dry periods of extremely dry years , the largest increment with pollutant concentration caused by salinity intrusion was not higher than 0.22mg/L.The indices DO, COD, BOD5 , NH3-N, TP, TN, FN, oil, and Hg remained superior to class III, although TP deteriorated from class III to class IV .
