摘要
详细地介绍了雨水集蓄利用系统，系统地分析了集流效率与降雨等级、下垫面材料及坡度的关系，指出雨水利用是黄土高原农业可持续发展的有效途径，并对当前存在的问题进行了讨论。
The rainwater catchment system was introduced,the relationships among efficiency of runoff catchment and rainfall grade,material of surface and slope gradient were analysed systematically.The results revealed rainwater utilization is the available way to agricultural sustainable development in loess plateau.The current problems of rainwater utilization were also disussed.
