| 摘 要： | 在遥感和GIS技术支持下,应用SWAT(Soil and Water Assessment Tool)分布式模型对开都河流域1988-2009年逐月径流进行模拟。结果表明:模拟结果与实测径流较吻合,校准期(1990-2000年)效率系数为0.58,平均相对误差为-5.7%,线性拟合度为0.8,验证期(2000-2009年)的结果与校准期接近,均达到了模型的评价标准,结果具有一定的可信度,SWAT模型适用于开都河流域的径流模拟;季节性融雪是研究区径流形成的重要组成,结合研究区的特性,确定了研究区的各项积雪/融雪参数,提高了冬春季节径流模拟的准确性。

| Abstract: | With the help of RS and GIS,monthly runoff in the Kaidu river basin from 1988 to 2009 was simulated by using SWAT hydrological model.The result showed that the simulation result was credible and consistent with the measured runoff.During the calibration period(1990-2000) the Nash-suttcliffes coefficient was 0.58,and the average relative error and linear fit were-5.7% and 0.8,while the result of validation period(2000-2009) was close to calibration period,and SWAT model was appropriate to simulate the runoff in the Kaidu River Basin.Seasonal snowmelt was an important component of the study area runoff.Based on the characteristics of the study area,this article had identified the snow/snowmelt parameters,aid to improve the accuracy of the winter and spring runoff simulation. |
