山区雨水利用技术及分析计算

Stromwater utilization technique in mountainous area

邢台市西部山区年降水量集中,水资源利用率低。结合该区特点,利用天然山场集蓄雨水,作为农业灌溉的水源,取得良好的效果。通过对该区降雨特性及时空分布分析,对利用自然山场集雨技术进行分析计算,包括天然山场单位面积集水量计算、蓄水工程容量的设计计算等,为山区农业发展、雨水利用提供科学依据。

As the annual precipitation in the mountainous area west of Xingtai City accumulates, the water resources are usually not sufficiently utilized. There is an effective method for gathering stormwater in natural mountain fields for irrigation. On the basis of the spatial and temporal distribution of precipitation, the amount of water gathered in a unit area and the design capacity of water storage projects were calculated. This method is also helpful for agricultural development and stormwater utilization in other mountainous areas.
