摘　　要：古建筑外墙表面生长的生物结皮可能导致墙面表层材料的生物退化,进而破坏其结构,但目前这方面的研究较少。选取明显陵建筑外墙表面的生物结皮,研究其微生物群落和理化性质变化对周围环境因素的响应。结果表明:生物退化墙面材料具有内部多孔性和渗透性,积累了一定含量的石膏和一水草酸钙等建筑材料的典型退化产物;墙体材料嵌着生长含蓝藻、苔藓、细菌和真菌的生物结皮;建筑外墙表面的生物结皮的生长,改变了外墙表面材料的结构,促进了建筑表面的生物退化。该研究可为明显陵墓区古建筑的保护提供参考。The growth of biological soil crusts(BSCs)on the exterior wall surface of ancient buildings may lead to the degradation of the wall surface material and damage to the wall structure.However,little information is available.In this study,the BSCs on the exterior walls of ancient buildings in the Xianling Mausoleum area of Ming Dynasty is selected to study the response of its microbial communities and physicochemical properties to the surrounding environmental factors.The results show that:the surface of biodegraded wall materials have internal porosity and permeability,thus there are a certain amount of gypsum,calcium oxalate monohydrate and other typical degraded products of building materials on the surface of the wall;the wall material is embedded with BSCs that grow cyanobacteria,moss,bacteria and fungi;it is found that the growth of BSCs on the exterior wall of the building changes the structure of the surface material of the exterior wall and promotes the biological degradation of the building surface.The study aims to provide reference for the protection of ancient buildings in the Xianling Mausoleum area of Ming Dynasty.
