摘要: 则岔石林地质公园位于甘肃省碌曲县,该处地貌完整地保存了高寒喀斯特的特征,具有典型性与稀有性。为了揭示其自然科学价值,促进自然资源开发与景观保护,基于前人工作基础,通过野外地质调查,以碌曲县区域地学为背景,介绍了则岔石林地质公园的喀斯特地貌类型,即以高原石林为主,一线天为亮点,小型溶洞为辅。继而从地质构造、岩性、水文气候、生物因素四方面分析了园内喀斯特地貌的形成机制。对完善我国高海拔地区岩溶系列地质遗迹的科学研究具有一定意义。同时,高寒喀斯特的生态化对南方喀斯特沙漠化的治理具有良好的示范作用。

Abstract: Zecha Stone Forest Geopark is located in Luqu County,Gansu Province,China.The landform in this area keeps the intact features of alpine-arctic karst,with typicality and rarity.In order to reveal its natural and scientific value,and to promote the natural resource development and landscape protection,the regional geological and geographic backgrounds of Luqu are briefed based on previous work and field investigation.The types of karst landform in Zecha Stone Forest Geopark have been introduced,which include the highland stone forest as the majority,the thin strip of sky as lightspot and the small karst caves as complementarities.The formation mechanism of the karst landform has been further analyzed from four aspects:tectonics,lithology,climate and biology.The results show that the tectonic movement,the development of joint fissures,and the difference of rocks cementation degrees laid a foundation for the formation of karst landscape.Moreover,under the alpine-arctic and dank climate condition with great changes,water corrosion,frost denudation,and weathering formed the unique alpine-arctic karst landscape in this area,which was characterized by many bedrocks and steep walls,tall stone forest and pillars,a few karst caves with poor connectivity and small size.The research provided some academic information of the karst landform in Zecha Stone Forest Geopark,which has certain significance in the scientific research on karst geological relics in high altitude areas of China.The ecologicalization of alpine-arctic karst provided a good reference for the governance of karst desertification in the south part of China.

Key words: Karst landform, formation mechanism, stone forest, Eastern Qinghai-Tibet Plateau, Luqu
