中文摘要：

采用由武汉大学李兰教授开发的LL-Ⅲ全分布式水文模型来研究流域水资源．在模型中，利用了大量的GIS和RS数据及信息研究流域水资源的时空变化，分析气候变化和人类活动带来的影响．模拟结果表明，LL-Ⅲ分布式水文模型适用于干旱半干旱地区的水资源模拟研究．

英文摘要：

The LL-Ⅲ （Developed by Prof. Lilan, Wuhan University） full distributed hydrologic model is adopted to make research of watershed water resources. In this model, GIS and RS data and information are used to simulate spatial and temporal variation rules of water resources and influence generated by climate change and human interferences. It is shown that the LL-Ⅲ distributed hydrological model can be applied to water resources research in arid and semiarid areas.
