干旱缺水与水土流失并存是制约干旱半干旱地区经济社会可持续发展的主要限制因子,坡面降雨径流既是产生水土流失的动力,又是缓解干旱缺水的重要水源。通过地表径流调控手段,消除水土流失动力,同步实现水土流失治理与水土资源高效利用一直是近年来人们研究的热点课题。近年
The coexistence of arid scarcity and soil erosion is the main limiting factor restricting the sustainable development of economy and society in arid and semi-arid areas. Slope rainfall runoff is not only the driving force behind water and soil loss, but also the important source of water to alleviate drought and water shortage. It has been a hot topic that people research in recent years through the means of surface runoff regulation and control to eliminate the motivation of soil and water loss and to realize the simultaneous control of soil and water loss and the efficient utilization of water and soil resources. in recent years
