摘　　要：贵州中部石灰岩地区约有８７种气生藻，在岩石表面的约有４４种。旱生种类的生长和空气湿度有关，潮湿环境中主要以兰藻为主；在树干表面生长的藻类约１４种，针叶树上出现的频度最高，分布多在距地面ｌｍ以下的树干上；在人工建筑物表面生活的气生藻约１６种，８１％上的种类在混凝土墙上可以找到；在土壤表面生活的藻类约４６种，其生长和土壤条件有关。在各类气生藻中，兰藻是石面环境中的优势种群；树干表面和人工建筑物表面以绿藻为优势种群；硅藻和黄藻主要生长于土壤表面。taxa of aerial algae exist in karst region of middle Guizhou Province. Of all.44 taxa grow on the limestone surface. 14 taxa grow on the tree bark and most of them grow on the bark of tree below 1 meter height. 16 taxa grow on the surface of building and 81% taxa can be found on concrete. 46 taxa live on the surface of soil and their growth are associated with the condition of soil. Among aerophtische,cyanophta are dominant population on rock ,Chlorophyto are dominant population on the surface of tree and building. But Diatom and Xanthophyceae are dominant population on the surface of soil.
