敦煌莫高窟是全国重点文物保护单位,并列入世界文化遗产清单。长期以来,这里受风沙侵害,并已危胁到洞窟的安全。过去的半个世纪里,虽然采取了一系列的防护措施,但因防护位置不当,事倍功半。根据风沙运动规律和风沙危害方式,评估了已经建立的防沙工程的效果,强调了防止吹沙和保护莫高窟的“六带一体”防沙体系的必要性和持久性。据此方案,阻沙带应建立在窟顶大沙山前缘作为前壁,窟顶戈壁作为输沙带,窟体作为固沙带
Dunhuang Mogao Grottoes is a national key cultural relics protection unit, and included in the list of world cultural heritage. For a long time, it has been hit by sandstorms and has threatened the safety of caves. Over the past half century, although a series of protective measures have been taken, it has done more with less due to improper protection. According to the law of sand movement and the hazard of sandstorm, the effect of sand control project has been evaluated and the necessity and persistence of sand prevention system to prevent sand blow and protect Mogao Grottoes have been emphasized. According to this plan, the sand-blocking belt should be established on the front of Dasha Mountain in the top of the cave as the front wall, the top of the cave as the sand transport belt, and the cave as the sand-fixing belt
