| 中文摘要: |
| 汉中天坑群的发现对于分析南北过渡带喀斯特地质环境具有重要意义。本文以骆家坝天坑群喀斯特为例，通过资料梳理和实地调查，总结喀斯特形态组合特征，深入分析喀斯特形成原因，揭示南北过渡带局部构造特征。结果表明:研究区天坑群主要发育于喀斯特台原面上，发育有最具特色的崩塌型天坑群。受新构造运动间歇式隆升影响，喀斯特的发育具有层状特征，天坑、竖井、溶洞和峰丛洼地的分布均呈现分层性。受构造作用的影响，研究区溶洞中干洞较多，退化作用明显。因此，未来要加强区域生态环境保护，防止溶洞地质灾害的频发。 |
| 英文摘要: |
| The discovery of Tiankeng group in Hanzhong is of great significance to the analysis of karst geological environment in the North-South transitional zone. In this paper, karst Tiankeng group in Luojiaba is taken as an example. Through .eld investigation and data sorting, the characteristics of karst morphological combination are summarized, and the causes of karst formation are deeply analyzed to reveal the characteristics of locally tectonic structure in the North-South transition zone.The results have shown: The Tiankeng group is mainly developed on the original surface of karst platform and has the most characteristic of collapse. In.uenced by the intermittent uplift of neotectonic movement, the development of karst has layered characteristics, and the distribution of Tiankeng, shaft, karst cave and peak cluster depression is strati.ed. Due to the in.uence of tectonism, there are many dry caves in the study area which are obvious degradation. Therefore, it is necessary to strengthen the regional ecological environment protection in the future to prevent the frequent occurrence of geological disasters in karst cave. |
