摘  要：
甘肃河西沙区经过60年左右的防沙治沙,绿洲边缘上风向形成了一条积沙带。对积沙带的研究表明,积沙带的形成有利于绿洲边缘的防风阻沙,且防御风的作用随风速的增大而增强。今后应将绿洲边缘防沙治沙的重点放在积沙带上,尤其是积沙带的沙脊线上,而对荒漠—绿洲过渡带实行封育。这样就可以大面积压缩实施农业生态工程措施的范围,提高防沙治沙的投资效益。

摘  要：
A accumulated sand-belt was formed in upper wind direction of oasis edge in Hexi desert area of Gansu province through prevening and controling desertification for 60 years or so. Study on accumulated sand-belt indicated that the formation of accumulated sand-belt was beneficial to wind and sand resistance of oasis edge. And its fuction of preventing wind strengthened with the increases of wind speed. The emphasis of prevening and controling desertification for oasis edge should be placed on accumulated sand-belt in the future. Especially the emphasis was sand ridges lind of accumulated sand-belt. Afforestation was implemented in desert oasis transitional zone. This could large area compress range of implementing agricultural ecological engineering measures and improve investment benefit of prevening and controling desertification.
