鸣沙山、月牙泉是敦煌风景名胜区的主要景点。在浩瀚的沙漠之中一弯清泉碧波澄澈、清明如镜,泉与沙山构成了奇特的自然景观。 明、清之际,在月牙泉南岸的台地上曾建有玉皇阁、三清观等建筑,后因年久失修濒于倒塌,于1968年拆除。20多年来南沙山坡脚的流沙侵入遗界25米之多。 今天建设的月牙泉建筑群既是风景旅游建筑又是生态建筑,要做到利于治沙维系沙山与清泉的平衡。从已建成的部份建筑来看,建筑物南墙与山体落沙坡脚保持的一定距离,形成利于聚风的通道,起到人为增大气流上升力的作用,促进了下滑沙体向山顶运动。目前南山坡脚已明显回升,达到了预期的效果。 Mingsha Mountain and Crescent Moon Spring are the main attractions of the Dunhuang Scenic Area. In the vast expanse of the desert, the blue waters are clear, clear and bright like mirrors, and springs and sand mountains form a unique natural landscape. During the Ming and Qing dynasties, buildings such as Yuhuangge and Sanqingguan were built on the terraces of the south bank of the Crescent Lake. They were later demolished due to the disrepair and collapse. For more than 20 years, sand flowing from the foot of the Nansha Mountain has invaded as many as 25 meters. Today’s Crescent Moon Spring Building Complex is both a scenic tourism building and an ecological building. It is necessary to make it easier for the sand to maintain the balance between Shashan and Qingquan. From the perspective of some of the existing buildings, the south wall of the building is at a certain distance from the foot of the mountain, forming a path conducive to gathering winds. This has the effect of artificially increasing the air flow rising force and promoting the downward sliding sand body to the top of the mountain. movement. At present, the foothills of Nanshan have rebounded significantly and have achieved the expected results.
