摘    要:在农牧交错带以小麦地为对照,研究退耕建植草地植被及天然草地植被的水土保持作用。结果表明,退耕建植草地植被可以明显减轻土壤风蚀程度,并有利于土壤在雨季对降水的蓄积;天然草地植被与农田植被相比,可以较好地减轻水蚀的发生。

关 键 词:农牧交错带  草地植被  水土保持作用  风蚀  水蚀

Abstract:The research, conducted in the agro-pastoral belt of northern China, discloses the result that when a piece of land planted with forages, it could reduce the wind erosion degree and save up the soil water reserves more than that planted with wheat.Comparing with the cropland,natural grassland vegetation could reduce the water erosion better.
Keywords:agro-pastoral transitional zone  transforming cropland into grassland  wind erosion  water erosion
