摘　　要：赣州通天岩留下了128品历代摩崖石刻,因历经风吹雨淋,大部分摩崖书法都出现粉化、开裂、脱落等情况。“同济”石刻自2006年至2020年间,风化日益严重,亟待进行抢救性保护。利用多种图像处理软件,分析了“同济”石刻剥落速率。14年间,石刻表面有效面积减少了54%,预测在自然状态下,风化速率将进一步加快。图片信息处理方法适用于通天岩其它石刻的表面风化速率分析。128 stone inscriptions of ancient cliffs have been left in Tongtianyan,Ganzhou City,Jiangxi Province.Due to the natural weathering,the stone inscriptions exhibited significantly efflorescence,cracks,and spalling.Weathering of“Tongji”stone inscription has severe damage since 2006.And an intervention is needed as soon as possible.Three image processing tools were to analyze employed the“Tongji”stone inscription weathering rate.Within 14 years,the effective area of the stone inscription surface has been reduced to 46%.It is predicted that under natural conditions,the weathering rate of“Tongji”stone inscription will further accelerate.The image information processing techniques employed to“Tongji”inscription is also suitable for the analysis of the surface weathering rate of other stone inscriptions in Tongtianyan.
