VIC陆面水文模型在白莲河流域径流模拟中的应用

Application of VIC Land Surface Hydrological Model in Flow Simulation of Bailian River Basin

本文从气象与水文水资源学科交叉的角度引进VIC陆面水文模型,将其应用于湖北省白莲河流域,探讨模型在中小流域降雨径流模拟中的适用性。本研究利用白莲河流域DEM、植被、土壤等数字化资料,经过模型预处理,建立了白莲河流域VIC模型框架。并进行了模型参数敏感性分析。模拟结果表明,模型基本能够反映该流域的日径流水文过程,具有一定适用性。

This paper introduced Variable Infiltration Capacity Land Surface Hydrological Model from the interdisciplinary aspect of hydrology and meteorology. The model was applied into Bailian River Basin of Hubei Province to discuss its adaptability in flow simulation of the medium or small basin. Combined with DEM, vegetation and soil data, through model pre-processing, the framework of VIC model for the Bailian River Basin was.established. The sensitivity of model parameters was made at last. The results showed that the model can reflect the daily flow hydrological process of the basin on the whole and can be adaptable for the basin.
