| 摘 要： | 渭北旱塬水资源贫乏,但相对而言,降水量却比较丰富,年平均550mm,是地表水的13.1倍,且有天然集流条件,可就近拦蓄利用,也可用于农业节水微灌,其增产效益可达20%～50%,水分利用率可达到0.8kg/mm,故潜力巨大,前景广阔.

| Abstract: | Water resources is shortage in Weibei dry plateau,but rainwater is rich,the precipitation is about 550 mm in average.The mean rainwater is 13.1 times of the ground water resources.And the rainwater is easy to be harvest and piped.If the water of cellar or cistern could be used in micro irrigation,it could increase crop yield by 20%～50%,the water use efficiency could be 0.8 kg/mm.So the rainwater harvesting and using is of great potential and broad prospects. |
