兴文石海地质公园石芽形态特征及影响因素

Morphological Characteristics and Controlling Factors of the Clints in Xingwen Shihai Global Geopark

石芽是四川兴文石海世界地质公园重要的地质遗迹,地质公园也因此而成名.论文分析了兴文石海世界地质公园石芽的空间分布、形态特征以及石芽发育的影响因素和形成演化过程.兴文石海石芽主要分布于地质公园内岩溶地貌最为发育的小岩湾园区和泰安石林园区,且以群聚型连片分布,形态以圆润低矮为主,受岩性、构造节理及区域气候和水文条件的影响,发展演化经历了岩体形成、抬升破裂、溶蚀及成型四大阶段.当前兴文石海世界地质公园石芽大部分处于发育成型阶段,具有较高的观赏价值.石芽是宝贵的地质遗迹,是地貌发展的一个暂时形态,是我们了解地质历史、古地理环境的重要地质遗迹之一.加强对石芽这类地质遗迹的研究,对于更好的保护与开发这一地质遗迹,做到在保护中开发、在开发中保护以及进行地质科普宣传具有十分重要的意义.

Clints are important geoheritages in Xingwen Shihai Global Geopark in Sichuan, and the geopark is fa- mous for them. It has a great significance to deepen the research of clints for the protection and exploitation of geo- heritage. The paper analysed the spatial distribution＇ morphological characteristics, developmental influencing fac- tors, and the process of evolution of the clints in Xingwen Shihai Global Geopark. The clints in Xingwen Shihai were mainly distributed in the most karst-developed gardens, namely, Xiaoyanwan garden and Taianshilin garden, and in the type of cluster. The shapes of the most elints were fruity and low. Because of the impact of lithology, structural joints, regional climate and hydrological conditions, the process of evolution of the clints included four stages the formation of the rock, uplifting rupture, dissolution and shaping. Currently,the majority of the clints in Xingwen Geopark has been in the developed forming stage, possessing a high ornamental value. Clints are valua- ble and rare as a temporary form of the landscape. They are the important geological sites for us to explore the geo- logical history and the ancient geographical environment.
