摘　　要：以横山水库为例,采用SWAT模型模拟分析了低影响开发模式对雨水利用的实际效果,并与传统开发模式的模拟结果进行了比较。结果表明,两种开发模式均使入库水量增加,但低影响开发模式下入库水量的增幅小于传统开发模式,二者最大相差19.66%;两种开发模式均使入库污染物减少,但低影响开发模式下入库污染量的降幅高于传统开发模式,二者最大相差5.46%(NH3-N)、4.63%(TN)、5.18%(TP)。Taking Hengshan Reservoir for an example, SWAT model is used to analyze the practical effect of low im pact development （LID） mode on rainwater utilization. Compared with the traditional development mode, the simulation results show that the two kinds of development modes cause the increase of reservoir inflow; low impact development is lower than the traditional development, and the largest difference of effect reaches 19.66~0; two developments cause the reduce of the pollutants into reservoir, but low impact development is higher than the traditional development; the largest 46%, and the total nitrogen pollutants is 4.63%, and phos
