沙棘主要分布于我国华北和西北地区,垂直分布在海拔1000—4000米之间的山地、丘陵、阳坡、阴坡、陡坡、阶地和河岸、河谷以及弱度盐碱化地段。沙棘根系发达,株丛繁茂,种植沙棘防止水土流失效果极为显著。沙棘与杨、柳、榆、油松、刺槐等乔木树种组成混交林,不但能促进乔木生长,其根系还能改良土壤,形成防止水土流失的理想林型。 Seabuckthorn is mainly distributed in North China and Northwest China, and is vertically distributed in mountains, hills, sunny slopes, shady slopes, steep slopes, terraces and riparians, valleys, and weakly salinized areas between 1000 and 4000 meters above sea level. Seabuckthorn developed root system, bush lush, planting seabuckthorn soil and water loss prevention effect is extremely significant. Seabuckthorn and poplar, willow, elm, pine, acacia and other tree species constitute mixed forest, not only can promote the growth of trees, but also improve the root system of soil, forming the ideal forest to prevent soil erosion.
