半干旱黄土丘陵区坡地雨水资源化工程技术研究

Engineering and Technological Research on the Rainwater Resources in Semiarid Loess Hilly Region of Sloping Field

以水土资源的保育和高效利用为指导,对半干旱黄土丘陵区目前实施的"88542"水平沟、水平阶、鱼鳞坑、回字型整地等几种坡地雨水资源化工程技术措施进行了研究。对提高雨水资源化程度和利用效率、缓解危害程度,具有重要的科学价值和生产示范推广价值。

Under the guidance of water and soil resources care and highly effective use,several project technical methods of rainwater resources in sloping field,such as the ＂88542＂ horizontal ditch,horizontal step and the hollow of fish scale,were studied,which had important scientific value and production demonstration value for improving rainwater resources degree and utilization efficiency as well as alleviating harm degree.
