摘要
将TOPMODEL模型应用到安徽水阳江流域,检验其在湿润地区的径流模拟能力,得到了较好的模拟结果。同时,利用安徽水阳江流域不同分辨率的DEM数据,进行了DEM分辨率对TOPMODEL模型的模拟结果的敏感性实验分析,结果表明,随着流域DEM数据分辨率的降低,模型的确定性系数也随之降低,模型对流域的DEM数据是敏感的。
In this paper, the TOPMODEL is applied to the Shuiyangjiang Catchment in Anhui Province to validate its simulation capacity in the humid areas and good daily model results are derived. Furthermore, using data of different DEM resolutions of the Shuiyangjiang Catchment in Anhui Province, the sensitivity analysis of the TOPMODEL＇s results to DEM Resolutions has been done. It can be seen that the determination coefficient of the model will decrease as the catchment DEM resolutions decrease. Therefore the model results are sensitive to the different DEM resolutions.
