摘要: 塔里木沙漠公路位于塔里木盆地,纵贯塔克拉玛干大沙漠,集沙漠特征与温带大陆性气候于一体,不少地段曾因流沙较为严重,造成了工程施工的难度,通过对沙漠公路塔中段两侧不同下垫面进行小气候分析,比较其差异来说明自然沙面、草方格、低矮防护林带、沙石路面等的不同防沙能力。从几种防沙效果来看,沙石路面短期内有一定的压沙作用,但长期效果不好;草方格短期效果较好,但随着时间推移,防沙效果逐渐减弱;防护林带体系随着林带的逐渐长成,效果将会越来越好,属于生态型防沙,意义重大而且深远。

关键词: 下垫面, 沙漠公路, 小气候, 林带, 草方格, 沙石路面

Abstract: The Taklimakan Desert Highway longitudinally crosses the Tarim Basin that situates in the temperate continental climate zone.Sand encroaching disaster is severe along the desert highway.The defensive ability of different shelters was evaluated through microclimate analysis of various underlying surfaces on both sides of middle desert highway section.It was found that grit road has certain ephemeral effect of covering sand,but has no long-time effect.Straw checkerboard has better effect,but the ability against quicksand became weaker with time elapsing.As ecotype,forest shelter will act well more and more in the processes of growing.

Key words: underlying surface, desert highway, microclimate, forest belt, straw checkerboard, grit road
