壁画保护修复是萨迦寺保护维修工程的重要组成部分。依据《中国文物古迹保护准则》,在前期壁画保护现状调查评估、室内实验的基础上,有针对性地开展了萨迦寺壁画保护修复现场试验研究。现场试验选取块石墙和夯土墙体上的地仗空鼓、开裂错位、颜料层起甲、地仗酥碱等几种典型壁画病害,根据“最大兼容和最小干涉”的保护修复原则,进行了保护修复材料和现场修复技术的筛选研究,取得了满意的效果,为大面积开展修复工作奠定了基础。

The conservation and restoration of wall-painting is one of the important part of the conservation project of Sajia Temple. According to the Principles for the conservation of Heritage Sites in China ,we have laid emphasis upon a careful investigation of the site condition and then combining with the laboratory study, the field testing study of conservation and restoration of wall-painting in sajia Temple had been completed. The topical deteriorations distributed in the stone wall and rammed wall were chosen. These deterioration facts include detachment and crack of the plaster, flaking of color layer, decay by salts of the plaster. Based on the basic conservation principles of wall-painting which are maximum compatible of the conservation material and minimum intervention, the chosen tests of the conservation materials and techniques were successfully carried out.
