| 摘 要： | 通过对黄土高原水资源现状分析,提出了采用消能淤泥坑,通过直接、间接将路面雨水引入农田"土壤水库"或时空可调节的自压式集流水窖等贮水设备中,并采用一定的耕作农艺措施将路面雨水利用到农田中的方法和技术.多年的甘肃定西试验和实践表明,使用这种技术不仅提高了天然降水的利用效率,而且简单易行,是黄土高原地区农业雨水资源利用的一个有效途径,同时该技术具有防止水土流失和改善旱区农业生态环境的效应.

| Abstract: | Basing on analysis of the situation of water resources in Loess plateau areas,this paper propounded the engineering and agricultural technology and the method with direct and indirect,which draw rainwater on road surface into "soil reservoir" of farmland or water cellar with free atmospheric pressure using silt delve of eliminate energy.Experiment and practice in Dingxi areas of Gansu province show that this method and technology could not only enhance precipitation utilize efficiency but be simple and easy to carry out,thus is an efficient way of agriculture rainwater use in Loess Plateau areas,meanwhile this technology has effect on preventing soil and water erosion and improving agricultural ecology in the area. |
