摘　　要：研究分析了晋南自然降水的规律和特点,为旱地集雨提供了重要的理论依据。指出可以通过蓄集径流雨水来调节降水的时空分布,以丰补欠,以余补缺,充分利用天然降雨,提高旱地农作物产量,增加旱区农民收入。This study analysed the rules and characteristics of rainfall in south of Shanxi, which supply an important theory basis for rainfall harvesting.It is recommended to regulate the distribution of rainfall in space-time through gathering the rainwater run-off. Therefore to make the best of the rainwater to compensate the shortage in dry land.It also increases the crop yield and income of the farmer in this region.
