摘　　要：贵州兴义拥有不可再生的独特地质遗迹资源——喀斯特地貌。其地貌景观特征及成因研究是贵州地质旅游开发与管理的重要支撑。经野外考察发现,兴义喀斯特地貌显示出锥状喀斯特、塔状喀斯特及针状喀斯特3种不同类型。此外,兴义溶洞垂向分布集中在1380~1450 m、1250~1280 m和1150~1180 m^(3)个高程区域。通过ArcGIS分析发现,溶洞三级高程范围的规律亦反映在贵州兴义地势高差规律上,且大量溶洞分布于河谷密集发育区,此外,河谷的流向与构造薄弱带相契合。在此研究背景下,分析了地貌景观的成因,包括对岩性、构造、水文,以及海拔等因素对喀斯特地貌分布的影响。Xingyi,Guizhou Province has a unique geological heritage resource-karst landform.The study of its geomorphological characteristics and causes is an important support for the development and management of geological tourism in Guizhou.According to the field investigation,karst landform of Xingyi shows different types:cone karst,tower karst and needle karst.Additionally,the vertical distribution of karst caves is concentrated in three areas:1380-1450 m,1250-1280 m,and 1150-1180 m.In this paper,aided by ArcGIS software,it was found that the law of the three-level elevation range of karst caves was also reflected in the law of terrain height difference in Xingyi,Guizhou.A large number of karst caves were distributed in the densely developed areas of the river valley,and the flow direction of the river valley was consistent with the structural weak zone.Under this research background,the causes of geomorphology and landscape were analyzed,inclu ding the influences of lithology,structure,hydrology,altitude and other factors on karst geomorphology distribution.
