摘　　要：针对浑善达克沙地固定沙丘活化形成的风蚀坑问题,采取工程固沙和植物治沙技术,重建风蚀坑植被。结果表明:采用不同材料、不同规格沙障,当年风蚀坑风蚀得到控制,植被盖度平均达到14.7%;3年后风蚀坑内植被覆盖率平均为35%～65%,并且植物种组成和物种丰富度随治理年限的延长而增加,促进风蚀坑植物种趋于正向演替过程,巩固了治沙成果。In view of blowout formed by activation of fixed dune in Hunshandake Sandy Land, the vegetation in blowout have been reconstructed by use of the technology of sand fixation and controlling sand with vegetation. The results show that wind erosion can be controlled in same year by use of different materials and sand barriers in different sizes, the average vegetation coverage is 14.7%, and after three years the average coverage in blowout is 35%-65%. With the extension of controlling year, the plant species composition and species richness have been increased, which promote plant species in blowout to tend to the positive succession and consolidate the achievement of controlling sand.
