关于魏晋墓砖壁画色彩保护的探索

为探索嘉峪关魏晋墓壁画色彩的保护，把魏晋墓18座已发掘墓葬中现阶段能参观的4座砖壁画墓划分为未开发组、研究性半开放组和完全性开放组进行研究。结果发现砖壁画色彩褪变的主要原因是游客参观时呼出的二氧化碳气体、水汽及人体产生的未知名气体等因素的影响，且水汽是最大的媒体介质。从而提出了进一步加强砖壁画保护措施。

Exploration on the protection of the brick fresco color of the Wei Jin ancient tombs

On the vast Gobi desert scattered are numbers of ancient tombs, among which 18 have been unearthed. At present, only 4 tombs are opend to the tourists. After a careful study of these tombs, it was found that the colour of the brick murals is declining, especially in the opened tombs (in this essay, the tombs into three classes were divided: openeed tombs, studied tombs and unopened tombs). It's due to CO 2 vapour, H 2O vapour, unknown gas and so on, that people give off when they are visiting the tombs. Of all these factors, H 2O vapour may be the most important medium. As a result, proposed are the further protection measures for the valuable brick murals.
