摘　　要：在分析人工湖降雨量与蒸发量差额、计算人工湖仅设垂直防渗墙时的渗漏量、测算周边地区雨水汇入量的基础上,利用水量平衡方程,对梦泽湖进行水位变化幅度核算。结果表明,梦泽湖在湖周边0.55 km2地区雨水径流补给湖水的基础上,水平方向上可用夯实的粘土防渗墙进行防渗处理,正常年份水位变化量在梦泽湖水位的设计波动范围内,即不需要强制补水其水量就能满足设计要求。若取湖水作为地区浇洒用水,则需采用自来水进行等量补偿。According to the water quantity balance equation, the rainfall and evaporation from the surface of the lake is analyzed, seepage quantity from vertical and horizontal sides of the lake is calculated with Darcy＇s Law, and the rain runoff discharging into Mengze Lake from the surrounding area is calculated also. The result indicates that if the seepage from the horizontal side of the lake is controlled with rammed wall together with the rain runoff from 0.55 km2 surrounding area of the lake feeding, the fluctuation of the lake can meet control requirement without any enforced water in normal years. If the water of Mengze Lake is used for road sprinkling and field plantation, it＇s necessary to be compensated with the same quantity from municipal water net.
