摘　　要：云南革香河流域嘉河五级流域内出露大面积泥盆系~三叠系碳酸盐岩地层,主要岩性为藻灰岩、微晶灰岩、生屑灰岩及白云岩,属强岩溶层组,流域内岩溶发育强烈。地表岩溶主要发育溶丘、洼地、槽谷、溶沟、溶槽、石芽、干谷、岩溶峡谷等。地下岩溶主要发育溶隙、天窗、竖井、落水洞、天坑、溶洞、地下河等。岩溶发育的主控因素一方面受到岩性控制,另一方面受到构造控制作用明显。The large area of carbonate rock stratum is exposed in the Jiahe Five-stage Basin of Gexiang River Basin in Yunnan.The main lithology is mainly algal limestone,micritic limestone,bioclast limestone and dolomite,which belongs to strong karst layer group.The karst development is strong in the basin.The surface karst mainly develops karst hillock,depression,trough,gully,karst trough,stone sprout,dry valley,karst canyon,etc.The underground karst mainly develops karst gap,skylight,shaft,dolina,sinkhole,karst cave,underground river,etc.The main controlling factors of karst development are controlled by lithology on the one hand,and by tectonic movement on the other hand.
