敦煌莫高窟的风沙危害与防治研究

A Study On The Blown Sand Disasters And It'sControl At Mogao Grottoes In Dunhuang

本文根据对莫高窟地区风沙活动规律和风沙危害方式的分析讨论 ,对截止目前已经实施的各种防沙治沙试验工程进行了评述 ,阐述了治理流沙的必要性和紧迫性 ,提出了莫高窟崖顶风沙危害防治的途径与对策。建议尽快建立一个由工程、生物、化学措施组成的多层次、多功能的综合防护体系 ,方可达到控制流沙、确保石窟文物免受风沙危害的目的。

Mogao grottoes have suffered from serious blown sand disasters.In the past half a century,many protective engineering projects were set up early or late on the top of the Mogao grottoes. Yet they were not fully effective one by one bec ause the ways and locations adopted to control sand were unreasonable.Based on t he regularities in motion of the blown sands and the threat way of the blown san ds,the paper is to review and assess the protective engineering in the past. At last the authors propose that a multi-functions,multi-measures protective system should be established in the view of long term’s sand controlling and blown sa nd environment feature.
