摘要
黄土高原地区年降雨量大多在350～450mm，干旱是限制山坡地农业生产的主要因子之一，该区群众在多年实践中总结出一套行之有效的雨水利用与节水灌溉技术措施，有效地保护了山坡地土壤资源，提高了水资源利用率，总结分析这些措施的技术特点、条件、效益及应用前景，对黄土高原地区山坡地水资源利用和生态农业建设具有十分重要的意义。
Yearly average rainfall is 35O~ 45Omm in Loess Plateau. Drought is a importantfactor to limit crop production in slope land. The local farmer already summarized a set of culturalmethods of rain use and saving water irrigation, which protected land resources effectively andincreased water resource use rate. The summarization on technologic characters, conditions,benefits, and utilizing foreground might accelerate water resources use and construction ofecological agriculture.
