| 摘 要： | 随着全球性干旱加剧与水资源问题的日益突出，雨水利用已成为世界范围内的一个课题。采取定位观测的方法，在山西省岚县香沟小流域研究集雨场的规划设计，地表处理技术，观测其集流量和集流效率，并对梯田作物有无补灌措施的生产效益进行对比试验研究。结果表明，集流量与降雨量和降雨强度之间是乘幂关系，降雨量越大，集流量越多；降雨强度越大，集流量也越多。水泥硬化小区的集流率较高；节水措施生产效益明显。雨水集流技术已成为解决水土流失和提高旱作农业生产力的一个结合点。

| Abstract: | With the intensification of the global shortage of water resources and drought,utilization of rain water has become a worldwide issue.In order to make a better study of the collection and utilization of rainfall so as to achieve the spatial and temporal redistribution of precipitation,the experiment adopted the method of fixed point observation and observed the outcomes by different surface processing techniques.It was found that the relation of the amount of collected rainfall to rainfall intensity was a p... |
