摘　　要：贵阳是典型的岩溶城市之一,苔藓植物在该市石灰岩壁广泛分布。本文通过对该岩溶地区19个样方的野外调查,报道该地石灰岩面上苔藓植物11科15属23种。根据溶蚀形态的大小及形态特征,可将苔藓植物在贵阳市岩溶区石灰岩的生物溶蚀状态可以分为四种类型,即:溶丝、溶斑、溶带、溶块,且这四种溶蚀形态之间存在着一定的相关性。此初步探究为进一步了解该地苔藓植物的生物多样性及其在城市生态中的功能积累了基本的数据。Guiyang is one of the typical karst cities,where bryophytes are growing widly on limestone.Based on 19 samples of bryophytes on limestone from the karst area of Guyiang city,we reported 23 bryophyte taxa in 15 genera and 11 familes.According to the characteristics of sizes and forms of bryological erosions on limestone,the forms of biological erosions can be devided into four types：erosional fuse,erosional plaques,erosional bands and erosional blocks.In addition,there are some relationship among the four types.Therefor,this primary study accumulates general baisic datas of bryophyte biodiversity and their functions in urban ecosystem in this area.
