黄土高原丘陵沟壑区沟道水资源利用模式初探

黄土高原丘陵沟壑区干旱缺水 ,要让有限的水资源支撑当地的生态农业建设 ,就要高效利用有限水资源 ,提高单位水的利用效率。通过在延安市燕儿沟的生产实践证明 ,在沟道中兴建截潜流工程 ,引水上山 ,发展坡地果园和保护地蔬菜微灌 ,是高效利用当地有限水资源的一种重要模式 ,很有推广价值

Drought and water lack are the most serious problems in hilly region of Loess Plateau. In order to support local eco agriculture construction, the limited water resources should be used efficiently and water use efficiency must be improved. Practice at Yan er gully in Yan an shows that establishing undercurrent interception engineering, leading water to hill and developing slope land orchard and vegetable micro irrigation at protected land is an important model to effective water resources use, and whi...
