Abstract：The samples of six moss plants include B.argenteum,B.unguiculata,E.julaceum,E.leptothollum,R japonicum and T vermicularia were collected from the karst rock desertification area in Puding of Guizhou,as the objects of this study.The carbonic anhydrase (CA) activity of the epilithic plants and the matrix of soil was studied,from which the analyses of bio-karst mechanism and governance of ecological environments in karst rocky desertification areas can be performed.The results show that there are some differ ences in carbonic anhydrase activity of six epilithic plants.The E.leptothollum is highest,reaching 272.99 U · g 1 (FW),while the minimum is 33.45 U · g-1 (FW) in R.japonicum.The B.argenteum base soil CA activity(101.81 U · g 1(dry soil) is the highest.The E.leptothollum is 15.95 U · g-1(dry soils) as the lowest.It could be concluded that CA activity has positive correlations with plant and soil carbonic anhydrase content of total phosphorus,kalium,gravel and soil moisture,respectively.
