中文摘要：
为了探讨SWAT模型在中国半湿润半干旱地区的适用性，依托GIS软件平台，将模型应用于中国伊河流域潭头以上地区，同时与新安江模型的同系列模拟结果进行了比较．结果表明，研究流域属于混合产流区，以蓄满产流为主的年份的模拟效果要好于以超渗产流为主的年份．
英文摘要：
In order to discuss its applicability in the semi-arid and semi-humid regions in China, the SWAT model was applied in the daily runoff process in the Yihe River basin upstream Tantou by use of GIS software. The simulated results were compared with those of the Xin＇ anjiang model. The results show that the study basin belongs to the mixed nmoff generation area, and the simulated precision of runoffs under the saturated storage is higher than that under the excess seepage.
