武陵山地区红色岩溶景观形成地质条件与演化模式研究

武陵山地区出露着层层叠叠，形似宫殿、堡垒，且与沟壑相嵌、具有较强观赏和开发利用价值的一类红色岩溶地貌景观。通过野外调查和资料分析，掌握此红色岩溶景观的分布范围，分析其发育的区域地质背景、地层岩性、地质构造及溶蚀作用等主要影响因素，以进一步解析其形成过程。结果表明：武陵山地区红色岩溶景观的形成经历了沉积成岩、抬升剥蚀、土下溶蚀成景三个主要演化阶段。

Geological conditions and evolution model of red karst landscape in the Wulingshan area, China

The Wulingshan area hosts a kind of red karst landscape with layers of fortresses and gullies embedded in a shape of palaces， which is of great value for viewing， development utilization and scientific research. Currently， there are few surveys and research reports on this type of landscape. To fill this gap， through field investigations and data analysis， this work delineated the distribution of the landscape， and analyzed the main influencing factors of its development， such as the regional geological background， stratum lithology， geological structure and dissolution， as well as its formation process. The results show that the generation of red karst landscape experienced three stages， sedimentary diagenesis， uplift and erosion， and under-soil dissolution into the landscape.
