摘　　要：岩溶地区发达的地下水系统,地下水与地表水之间,通过漏斗、裂隙等方式进行直接的水量交换,需要有一套地下水模型来描述其复杂的地下水汇流过程。模型在新安江模型基础上,模拟流域岩溶面积上进行地下水、地表水转换,又通过多个串并联的地下水库经行地下水汇流模拟。模型在平湖流域对其水循环过程进行了模拟,采用多目标粒子群优化算法MOPSO优化模型参数,用多年逐日实测数据对模型进行率定。结果表明模型率定期确定性系数平均能达到0.8以上,验证期确定性系数也能保证在0.78以上;采用数字滤波法和基流指数法分割得到的基流对地下水径流进行对比校验,表明基流与地下水径流间存在很高的关联度。The Karst region has a complicated groundwater system ,and water transfers directly between groundwater and surface water through funnels or cracks .A groundwater model needs to be developed to describe the complex process of groundwater runoff process .The model used in this paper is based on Xinanjiang Hydrological Model to simulate the transformation between surface wa‐ter and groundwater in karst areas ,and a multiple series-parallel underground reservoir group model is introduced into groundwater flow simulation .The model is applied successfully at Pinghu Basin .Multi-objective particle swarm optimization algorithm （MOPSO） is used to optimize model parameters ,and the years of measured daily data are used for model calibration and verification .The re‐sults show that the model rate is the average deterministic coefficient which can reach more than 0 .8 in calibration ,and it can guaran‐tee above 0 .78 in verification .With the help of digital filter method and the base flow index division method ,the base flow is com‐pared with the groundwater runoff ,which proves the connection between surface water and groundwater .
