摘要
甘肃省是我国石窟分布的重要地区之一,砂岩石窟表面风化一直是保护难题,通过现场调查发现,甘肃砂岩石窟浅表层风化有着明显的地域分布特征。甘肃砂岩石窟分布可分为三个区域:陇东地区、陇中地区、河西地区。浅表层风化受自然和人为环境影响,烟熏病害普遍存在;陇东地区主要病害为粉状风化、泛盐和植物病害;陇中地区黄河干流砂岩石窟以植物病害、粉状风化为主,支流高阶地砂岩石窟病害发育较弱;河西地区以植物病害、表面孔洞状风化为主。
Gansu Province is one of the most important areas for the distribution of grottoes in China.The surface weathering of sandstone grottoes has led to various problems in terms of preservation.According to field investigations,the surface weathering of sandstone grottoes in Gansu Province has obvious regional distribution characteristics,which could be divided into three main areas:Longdong ereas,Longzhong areas and Hexi-Corridor areas.Both natural and artificial factors contribute to the surface weathering of sandstone grottoes,and sootiness are widespread.The main problems in Longdong area include powdery weathering,salt damage,and plant-induced disease.In the stream of the Yellow River of Central Gansu Province,some critical issues are plant-induced disease and powdery weathering.Fortunately,the grottoes near the tributaries of the Yellow River exhibit relatively little damages.Finally,the major problems in the Hexi-Corridor area include plant-induced disease and surface cave-shaped weathering.
