岩溶地区的地表形态特征有溶沟、溶槽、石芽和石林;漏斗、落水洞和竖井;溶蚀洼地和坡立谷等。岩溶地区的地下形态特征有溶蚀裂隙及溶洞、暗河、石钟乳和石笋等。我国石灰岩地层形成的岩溶地区分布很广。这种地区在广西、贵州、云南、四川等地最多,其余湖南、广东、浙江、江苏、山东、山西等省均有规模大小不同的岩溶地区。此外,我国的西部和西北部在夹有石膏、岩盐的地层中,也有局部的岩溶分布。
Karst area of the surface morphological characteristics of dissolved ditch, solution tank, stone buds and stone forest; funnels, sinkholes and shafts; erosion depression and slope valleys. Underground forms of karst area are characterized by dissolution fractures and caves, underground rivers, stalactites and stalagmites. Karst areas formed by limestone formations in China are widely distributed. Such areas in Guangxi, Guizhou, Yunnan, Sichuan and other places up to the rest of Hunan, Guangdong, Zhejiang, Jiangsu, Shandong, Shanxi and other provinces have different sizes of karst areas. In addition, there are also local karst distributions in the western and northwestern parts of the strata that contain gypsum and rock salt.
