| Abstract | 敦煌莫高窟的部分壁畫受到起甲、酥堿、皰疹等多種病害的破壞,病害的產生與崖體中鹽分的運移有關,深入研究莫高窟崖體砂礫巖中鹽分分布特征,對科學防治莫高窟壁畫病害具有重要意義。通過對莫高窟第108窟西壁崖體砂礫巖中鹽分和莫高窟崖體頂部以下20m深度范圍內鹽分調查,發現莫高窟崖體砂礫巖中鹽分種類主要為硫酸鹽和氯鹽。整個崖體砂礫巖中鹽分在大范圍內分布較均勻,但在臨空面出現了鹽分集聚現象,在洞窟西壁和崖體頂部以下0.5m深度范圍內鹽分含量很高,平均為2.0%,最高為3.5%。本文首次從較深范圍內對莫高窟崖體砂礫巖中鹽分的分布特征進行了研究,這為以后莫高窟壁畫鹽害分析研究提供重要的數據支持。
The Dunhuang Mogao Grottoes site is famous for its exquisite wall paintings and statues.Some of these wall paintings have been damaged by flaking,efflorescence,blisters,and other types of deterioration.Many scholars believe the deterioration is related to salt migration from underlying cliffs into the wall paintings,which makes it very important to study the salt distribution characteristics in the Mogao Grotto cliffs in order to control further damage.An investigation of the salt in the west wall of cave 108 and at the top of the cliff at a depth of 20 meters shows that the main salt types are sulfate and chlorine conglomerated within the Mogao cliff.The salt distribution is even over a large scope,but a high concentration can be found toward the surface of the cliff face:salt content is very high on the surface of the west wall of the caves and in the cliff in a depth of 0.5 meters,with a highest value of 3.5% and an average value of 2.0%.This is the first study of the salt distribution characteristics of the Mogao Grotto cliffs,the researchers aim here to provide important supportive information for future data analysis of salt deterioration in Mogao murals. |
