摘　　要：依据拾桥河流域的多年平均生活和工业污染负荷量(以高锰酸盐指数作为代表)及多年水文条件,采用一维水质模型对南水北调引江济汉工程穿越前后的长湖最大支流——拾桥河的水质进行模拟。结果表明,由于输水渠的阻隔,拾桥河河口以上水位抬高1.3 m,水体流动性降低,高锰酸盐浓度值增幅达0.2～0.5 mg/L,水质出现不同程度的恶化。对此须予以重视。According to the yearly average life and industrial pollution burthen（with permanganate index as representative） of Shiqiao River drainage area,the single dimension water quality model was adopted to simulate the water quality of the biggest anabranch of the water diversion project from Changjiang River to Han River——Shiqiao River.The results showed that in virtue of the obstruct by water laying,as the bayou of Shiqiao River run up 1.3 meter,the water fluidity reduced and permanganate concentration amplitude was up to 0.2-0.5 mg/L and the water quality turned bad in some degree.Consequently attention should be paid.
