西南岩溶地区水资源预测评价中流域水文模型应用的特点及展望

Characteristic and expectation of application of watershed hydrological models in karst area Southwest China

在对西南岩溶地区水文地质条件分析的基础上,指出了三类流域水文模型在西南岩溶地区实际应用的可能性及困难;通过三个成功实例:桂林“丫吉模型”、洛塔干河猪场表层岩溶泉BP人工神经网络模型、刁江SW AT模型,分析了目前在西南岩溶地区应用流域水文模型的若干特点;提出了在下垫面条件复杂、流域含水介质结构空间差异性大的岩溶地区,特别是无监测资料地区,发展分布式水文模型是未来的研究方向。

Based on the analysis of hydrogeological conditions in karst area Southwest China, points out the possibility and difficulty to apply three kinds of watershed hydrological models to karst area in Southwest China, Through three successful examples such as Yaji model in Guilin, BP model of the epikarst spring in Ganhezhuchang, and SWAT model in Diaojiang, analyzes the present characteristic of application of watershed hydrological model in karst area Southwest China; presents that the distributed hydrological model will be the study direction in future in the karst area with complex underlying surface conditions, especially in Ungaged watershed.
