摘　　要：为研究团粒喷播技术构建的人工植被对风积沙地的防风固沙效果,以位于雅鲁藏布江沿岸的风积沙地和采用团粒喷播技术进行植被恢复的试验区为研究对象,本文分别采集2块区域的风速和风沙通量数据并进行对比分析。结果表明,在风沙天气过程中,植被恢复试验区相对于风积沙地的风速削减率平均达到26.19%,最高可达27.59%。另外,植被恢复试验区的风沙量整体被削减了83%,其中地表20 cm以下的风沙削减比例最高,达到93%,表明通过团粒喷播技术构建的人工植被具有较强的沙源阻截作用,极大程度上削减了风沙输送量。In order to research the sand-fixd effect of artificial vegetation constructed by FSA spraying-seeding technology on the wind-accumulated sand land,the wind-accumulated sand located along the Brahmaputra river and the experimental area using the technology of FSA spraying-seeding vegetation restoration were taken as the research objects,the data of wind speed and sand flux in two areas were collected and compared for analysis in this paper.The results show that the reduction rate of wind speed in the vegetation restoration test area is 26.19%on average and 27.59%at the highest.In addition,the whole amount of sand collected in vegetation restoration test area was reduced more than 83%,the highest cut proportion reach 93%,which below 20 cm of the sandy surface.Research suggests that artificial vegetation constructed by FSA spraying-seeding technology has strong sand source interception effect,the amount of sand has been reduced to a great extent.
