中文摘要	风沙危害是敦煌莫高窟保护面临的主要环境问题之一,建立一个完整的防护体系是解决这一问题的有效途径.在对20世纪80年代以来建立的防沙治沙试验工程防护效应分析研究的基础上,对敦煌莫高窟风沙危害综合防护体系设计进行了讨论.根据因地制宜,因害设防;以固为主,固、阻、输、导相结合;以工程和生物措施为主,兼顾化学固沙;高新技术与常规治理技术相结合;重点治理,分阶段实施与长远目标相结合的设计原则,认为根据不同地貌特征及地表组成物质,依次建立鸣沙山前缘流动沙丘和平坦沙地阻固区、窟顶戈壁防护区、洞体崖面固结区、石窟对面流动沙丘固定区、窟区防护林带建设区及天然植被封育保护区,可使危害莫高窟的风沙灾害得到有效控制,并达到莫高窟作为世界文化遗产和全国重点文物保护单位对环境质量的要求.
英文摘要	Mogao Grottoes is located in the southeastern marginal zone of the Dunhuang Basin, Gansu Province, and there are 492 grottoes with marvelous color murals and sculptures. In the region of Mogao Grottoes, it belongs the typical arid desert climate, the annual precipitation is only 23.2 mm but the annual evaporation is as high as 4347.9 mm, the annual, maximum and minimum temperatures are 10.6°C, 40.6°C and -21.5°C respectively, the average relative humidity is 32.2%, and the annual average and maximum wind speeds are 3.5 m/s and 21.2/s respectively. Spring water from Dangquan Spring is one of the main water sources in this region, and its annual runoff volume is 4.1xl06m3. Sand drift disasters occur frequently and are one of the main environmental problems at Mogao Grottoes, so it is an effective way to build a comprehensive sand drift control system. Based on analyzing and researching the sand drift control projects built since the 1980s, in this paper the design of the synthetic sand drift control system for protecting Mogao Grottoes is discussed. According to the designing principles to take measure to local conditions, combine sand-fixing with sand-obstructing, sand-transporting and sand-guiding, take engineering and biological measures with chemical sand-fixing measures, combine advanced techniques with traditional sand control ways, and consider both short-term and long-term effects of controlling sand drift, it is considered that 6 sub-regions should be divided in constructing the sand drift control system for protecting Mogao Grottoes with color murals and sculptures.
