摘　　要：为了减轻东汶河对云蒙湖水体的污染，在东汶河入湖口处设置前置库系统，对水质进行净化，从而达到拦截杂物，减小湖区淤积和净化水质的目的。前置库系统生态环境效益显著，全年对水体氮磷均具有较好的净化作用，净化率平均为20％-40％。另外，前置库生产的芦苇和香蒲及水产品等，取得了巨大的经济效益。In order to reduce Yunmeng Lake water pollution from Dongwen River, a pre-reservoir was built at the lake inlet of Dongwen River to purify water. The pre-reservoir can intercept sundries, reduce deposition and purify water. The pre-reservoir system has significant ecologi- cal benefit and high purification ratio to nitrogen and phosphorus, and the average purification ratio is 20% -40%. Typha orientalis, Phragmites australis and aquatic products in the pre-reservoir have great economic benefit.
