中文摘要	受全球气候变化和人类活动影响,青藏高原上的土地沙漠化正呈现加速发展态势。沙漠化产生的风沙堆积势必改变地表辐射和能量平衡状况,对较为敏感和脆弱的多年冻土环境造成影响,并可能影响青藏铁路路基的稳定性。因此,研究积沙对多年冻土的影响对于高原沙害防治、多年冻土保护和道路工程建设都具有重要的理论及现实意义。目前,前人已在青藏高原地表能量平衡研究方面取得了一些成果,并开始关注积沙对冻土温度影响问题。然而,由于已有观测资料的连续性、同步性和可比性等局限,对积沙地表辐射和能量平衡方面的研究还比较薄弱,积沙对冻土温度过程影响的研究结果尚不一致,而积沙对路基影响的问题也亟待开展研究。为此,本文提出了加强定位观测、开展室内低温实验以及数值模拟等建议,以期对今后的深入研究起到抛砖引玉作用。
英文摘要	Under the influences of climate change and human activities,the desertification in the Tibetan Plateau is taking on an increasing trend.The sand accumulation resulted from desertification could alter the radiation balance of ground surface,destroy the stable equilibrium state of permafrost,and could even affect the roadbed stability of Qinghai-Tibet Railway.Therefore,to study the influence of desertification on permafrost is significant to combat desertification,protect permafrost and construct road in the Tibetan Plateau. At present,some progresses in radiation balance of the Tibetan Plateau have been achieved by previous scholars and more attentions have been paid to the influences of sand accumulation on permafrost temperature. However,due to the shortage of observational data with continuity,synchronism and comparability, the study on radiation balance in sand surface ground is still weak,and the research findings about the influences of sand accumulation on permafrost temperature are not agree with each other.In addition,it is urgent to conduct the study on the influences of sand accumulation on roadbed.In order to carry out further research on this problem in future,some suggestions were put forward in this paper such as enhancing in-situ observation,conducting indoor experiments and carrying out numerical simulation.
