摘要
被誉为“墙壁上的博物馆”、“世界艺术画廊”的敦煌石窟,吸引着越来越多的旅游观光者和世界友好人士。然而,由于强烈的西南及西北风被运沙物质,常以风沙流的形式沿崖壁泄流而下,使许多洞窟前室或洞窟外露壁画受到沙割、沙打、磨蚀和掏蚀,洞窟安全受到威胁。早在六十年代,技术人员就采用草方格、碎石、挡风墙等方法进行防沙。
The paper is a report of stage positive results which have been made by the Dun huang Academy and the Getty Conservation lnstitute of the U. S. in the experiment of biological sand-fixation: the Mogaoku area. In order to select the proper sand-fixing plants to control sand movement, in the expriment we adopted the drip irrigation techniques to plant Hua Bang and the athers of four sand plants at the foot of the sand hills on the top of Mogao Grottoes, Through the observation and research,we found that it is a practical and effective measure to plant the sand-fixing plants to contral sand movemere in the Mogaoku area. The survived rate of Hua Bang and the others of four sand plants in 81.5-100％ the same year. The highest growth size of Hua band was to 135cm. They could complete the biological process of surviving, blooming and bearing seeds the same year.
