| 中文摘要: |
| 平塘塘边—罗甸董架天坑群位于处于规模宏大的小井地下河系统的临近排泄基准面的马鞍寨至小井一带集中分布，具有较大的旅游及科研潜力。地段内厚度巨大的可溶碳酸盐地层及复杂的地质构造为天坑群的发育提供了基础，地壳的不断间歇式提升和暗河系统不断的向上游溯源侵蚀使小井地下河暗河的埋深逐渐加大，由此使地下水不断汇聚、较大的水力坡度、地下水动态的巨幅变化，使岩溶发育具有向深性、迭加性和多阶段性特征，新构造运动是本区天坑形成较为重要的因素，依据岩溶发育的多期性特征，总结出天坑的形成模式。 |

| Dongjia Tiankeng group located in Maanzhai and Xiaojing area which is drainage datum plane of big Xiaojing groundwater system，has abundant tourism and scientific potential.Thick soluble carbonate layer and complex geologic structure supported the development of Tiankeng group，the ceaseless batch uplift of crust and upcurrent corrosion of groundwater system make the depth of Xiaojing groundwater system bigger and bigger，the groundwater collected continuously，big hvdraulic slope and change of groundwater dynamic make the karst development has the features of deep，superposition and multistage.Neotectonics is an important factor for the Tiankeng formation，the formation pattern of Tiankeng is summarized according to the multistage of karst development. |
