摘　　要：利用地理信息系统技术对中田舍流域数字高程模型(DEM)进行提取,获得地貌单位线中所需的地貌参数及其他流域信息,建立该流域的地貌单位线汇流模型,并利用实测资料验证其精度。结果表明:中田舍流域2016年3场洪水的模型模拟确定性系数均达到了0.9以上,模拟的洪峰与径流深的数值也较为相近,峰现时间的误差均在1 h之内。Technology of geographical information system was used to extract the digital elevation model （DEM） in Zhongtianshe River Basin, which obtained the geomorphic parameters and other watershed information acquired in the geomorphologic unit hydrograph, established the concentration model of geomorphologic unit hydrograph, and verified its accuracy by measured data. The results showed that the simulation coefficients of the 3 floods in the Zhongtianshe River Basin in 2016 had reached more than 0.9. The simulated flood peak and the runoff depth were also close, and the error of peak time was within 1h.
