摘　　要：黄土高原水土流失严重,区内可用于生态环境治理和畜牧业生产的植物种类相当缺乏。在黄土高原沟壑区进行的美国白蜡引种及复合造林试验表明:美国白蜡在黄土高原沟壑区引种栽培后适应性强,生长速度快;各种复合类型由于植物之间的有益共生,特别是中国沙棘、多年生香豌豆的固氮作用,可以很好地促进美国白蜡的生长。美国白蜡适宜在黄土高原及其周边地区生长,应采取间作、混交等复合栽植方式。The soil and water loss is severe in the Loess Plateau and the plant species that can be used for ecological environmental management and stock raising production is greatly short. The introduce of White Ash and tests of complex afforestation conducted in the gullied rolling loess area show that after introduce and cultivation, adaptability of White Ash is strong and growing speed fast in that area and; due to beneficial co-growing among plants, especially the function of nitrogen fixation of the Chinese Seabuckthorn and Everlasting Pea, various complex species can fairly promote the growth of White Ash. White Ash is suitable to grow in the Loess Plateau and its surrounding regions and should adopt the complex way of interplant and mixed trees.
