摘要
位于内蒙古西部的阿拉善高原分布着中国面积第二、第四大的巴丹吉林沙漠、腾格里沙漠,是中国北方粉尘的重要源区,也是西北路风沙进京的重要通道.这两大沙漠目前已被纳入新"三北"工程河西走廊-塔克拉玛干沙漠边缘阻击战的重点治理区域,斩断两大沙漠"握手"、锁边固沙是本区的治理难点.为了给"三北"工程风沙口治理和相关基础研究提供全面深入的参考,回顾了对两大沙漠物源和围绕雅布赖山形成的"握手"输沙带的重要研究进展,并提出了未来应围绕风沙源区和传输机制、锁边林草建设和防护林退化机制以及发挥风能资源优势等方面开展科研创新,以科技攻关带动"三北"工程攻坚,为打赢"三北"工程三大战役提供支撑.
Abstract
Located in the west of Inner Mongolia,the Alxa Plateau distributed the Badain Jaran Desert,the sec-ond largest in China,and the Tengger Desert,the fourth largest in China.This area is one of the most important sources of dust in the north China,and provide channels for the northwest road of dust storms to Beijing.These two deserts have been included in the Hexi Corridor battle of the new Great Green Wall(GGW).One of the es-sential tasks in this area is the construction of dune-preventing vegetation belts.This paper reviews the important research progress on two major desert provenances and the sand transport belts formed around the Yabrai Moun-tains,in order to provide reference for the GGW.In the future,basic research should be strengthened in studies of source areas and transport mechanism of aeolian sand,the construction of forest and grass on the edge and the degradation mechanism of shelter-forest,and how to take the advantages of wind energy resources in sand belt area,so as to provide scientific and technological support for winning the three battles of the GGW.
