摘要
我国“三北”地区由于自然条件的限制,森林资源极为贫乏,而灌丛植被却有着广泛地分布。在复杂的生境类型中,存在着相应多种多样的天然灌丛,从高寒落叶阔叶灌丛到温性落叶阔叶灌丛,象半干旱地区草原沙地的锦鸡儿灌丛、柳灌丛以及干旱地区河岸冲积平原盐渍化草甸土上的柽柳灌丛等都是长期与当地自然条件相适应的近于原生植被。
It is important to protect, transform and make proper use of the natural shrubs for maintaining ecological balance and improving the production of animal husbandry and sidelines in the 'three north' region. Taking an example of the shrubs in Wulanaodu area which is located in the east of the 'three north' region, this paper summarized the five years experiment (1981—1985) on three kinds of transformation measures:round enclosing, aboveground cutting and seeding. The tnatural shrubs in this region are devided into three types and each given a corresponding model for the rationaI utilization of the natural shrub resources.
