摘要

本研究以小流域实验观测为基础,利用GIS平台和遥感数据作为分布式水文模型SWAT。利用实测数据对子母河小流域的降雨径流过程进行了模拟。结果表明:确定参数后,径流一致性较好,模型效率系数为0.59。该模型能较好地模拟研究区降雨径流过程。通过确定的敏感性参数,确定了研究区雨季径流敏感性参数,为西溪河情水文模拟提供参考。

The Research Based on SWAT Model of Rainfall-Runoff Process Simulation in Zimu River in Nanxi River Basin
This study, based on the experimental observation of small watershed, uses the GIS platform and the remote sensing data as the distributed hydrological model SWAT. It uses the measured data to simulate the rainfall runoff process in the small watershed of Zi Mu river. The results show that the runoff is more consistent and the model efficiency coefficient is 0.59 after the parameters are determined. The model can better simulate the rainfall runoff process in the study area. Through the determined sensitivity parameters, the sensitivity parameters of the rain season runoff in the study area were identified which will provide reference for the hydrological modeling of the N anxi river state.
