摘要/Abstract

摘要： 乌兰布和沙漠是我国八大沙漠之一,处于我国北方半干旱与干旱区的转折位置上,进一步沙质荒漠化的潜在危险性。就乌兰布和沙漠东缘固沙植被恢复重建以及资源利用过程中发现的一些问题进行分析探讨,主要包括人工固沙植物种的选择与配置问题、绿洲外围天然植被破坏问题以及绿洲开发规模选择对未来固沙植被的潜在影响等问题。

Abstract: Ulanbuhe desert is one of the eight largest deserts in China. It is located on the transitional zone between semi-drought and drought area,and could be easily desertified further. The paper analyzed the problems existed in the process of sand fixing vegetation restoration and resource utilization, which mainly included species selection and stabilization, natural vegetation being destroyed around oasis,and the possible effect of oasis scale.
