利用窟野河王道恒塔站以上流域２０多次径流含沙量大于３００ｋｇ／ｍ３的降雨径流泥沙资料，初步分析了流域降雨空间分布及前期影响雨量对流域产沙的影响，并建立了流域降雨侵蚀产沙过程的水沙传递关系。研究结果表明：降雨空间分布及前期影响雨量对水沙传递关系的影响是显著的，此项研究对提高流域降雨侵蚀产沙预测预报精度和可靠性具有重要的意义。
Using the runoff and sediment data of more than 20 times of runoff sediment concentration more than 20 times over the Wangda Hengtai station in the Kuye River, the spatial distribution of precipitation in the watershed and the impact of the earlier rainfall on the sediment yield in the watershed were analyzed. Relationship between water and sediment transfer during rainfall erosion and sediment production. The results show that the spatial distribution of rainfall and the impact of rainfall on the transmission of water and sediment are significant. This study is of great significance to improve the accuracy and reliability of rainfall erosion and sediment yield.
