摘　　要：水文模型对于分析水文活动具有重要的参考意义。TOPMODEL模型是水文模型中应用最广泛的模型之一,本文对TOPMODEL模型的基本理论、基本方程、模型参数以及应用步骤进行阐述,并基于TOPMODEL模型对伊犁河流域进行径流模拟、洪水预报及水文计算模拟研究,模拟结果显示:TOPMODEL模型能够很好的再现伊犁河流域的洪水径流过程,有8个场的测定系数达到丙级以上精度,洪峰相对误差小于20%,合格率为88.9%,研究结果能够为伊犁河流域及相似流域水文活动的预报预警提供一定的理论和技术参考。Hydrological models have important reference significance for analyzing hydrological activities.TOPMODEL is one of the most widely used hydrological models.This paper describes the basic theory,basic equations,model parameters and application steps of TOPMODEL.Based on TOPMODEL,runoff simulation,flood prediction and hydrological calculation simulation of the Yili River Basin are carried out.The TOPMODEL model can well reproduce the flood runoff process in the Yili River Basin.The measured coefficients of 8 fields reach the accuracy of Class C,the relative error of flood peak is less than 20%,and the qualified rate is 88.9%.The research results can provide certain theoretical and technical reference for the forecast and early warning of hydrological activities in the Yili River Basin and similar basins.
