达玛沟遗址的壁画由于长期处于高湿和可溶盐含量较高的埋藏环境,加上出土后存放条件所限,壁画的颜料层和地仗层已产生了多种病害。为了长期保存这批珍贵遗产,选择有典型病害的三块壁画进行修复试验并重新制作轻质可移动的支撑体,为后续保护修复提供了指导和借鉴。经修复后的壁画安全稳定,便于陈列展览。 The frescoes at Dammacao site have been subject to various diseases due to long-term burial conditions with high humidity and soluble salt content, coupled with the limited storage conditions after the excavation. For long-term preservation of these precious heritages, three murals with typical diseases were chosen to be repaired and reworked to make lightweight movable supports, which provided guidance and reference for subsequent protection and restoration. After the restoration of the murals safe and stable, easy to display the exhibition.
