摘　　要：汉中天坑群由断崖、峡谷、石芽、石林、岩溶湖泊、峰丛、洼地、竖井、天坑等地表岩溶与溶洞、地下河、岩溶泉等地下岩溶组成,数量多、分布广泛、类型齐全。基于多年野外调查研究基础上,通过对陕西省汉中天坑群岩溶地质遗迹的分布、类型、组合等特征以及形成进行系统梳理和总结,结果表明:汉中天坑群是典型的岩溶台原区,在大地构造背景、地层岩石、水文地质及气候等条件的共同作用下,发育了完整的各种地表、地下岩溶组合,具有较高的科学价值和景观价值。Hanzhong Tiankeng cluster consists of such surface karst as cliffs,canyons,clint,stone forest,lakes,karst peak cluster,depressions,shaft and hole and such underground karst as karst cave,karst springs and underground river.The cluster is characterized by large quantities,wide distribution and the complete types.The paper,based on years of field trips and research,has systematically reviewed and summarized the distribution,types,combination and other typical characteristics of the geologic relics.The results show that Hanzhong Tiankeng cluster is typical of the original area,and that it has evolved into a complete composite with various surface and underground karst characteristics under the communal influence of the tectonic background,formation rock,hydrology and climate conditions.It proves to be of high scientific value and landscape value.
