基于SWIM模型的洱海流域产流模拟研究

Simulation on Erhai Basin Runoff Based on SWIM Model

利用DEM、土地利用图、气象水文观测数据,使用SWIM模型对洱海流域产流进行了模拟,比较模拟值和观测值得到效率系数为0.49,总流量相对误差为-18%。

By using DEM,land use map,meteorological and hydrological observation data,Erhai basin runoff was simulated based on SWIM model.The efficiency coefficient was 0.49 by comparing simulation value with observation value,the relative error of total flow was-18%.
