摘　　要：盐风化是莫高窟岩体风化的重要因素之一、本文研究了莫高窟盐风化作用的性质、机制和强度,通过对比分析,说明芒硝等可溶盐是主要的风化盐类.还阐述了莫高窟岩体盐风化的环境背景条件.Salt weathering is one of the important factors to weather the rock body at Mogao Grottoes. By a preliminary research on the property, mechanism and strength of salt weathering action, the paper proves that the Na2SO4, NaCl, MgSO4, CaSO4 · 2H2O, Ca(HCO3)2. are main materials to weather rocks in this area and points out the importance of moisture action in salt weathering process and sets forth the background of salt weathering in the rock. The purpose is to provide a scientific basis for the protection of the Dunhuang frescoes and the rock body of Grottoes.
