认识溶洞

溶洞形态万千、色彩纷呈，展现了大自然的鬼斧神工，但你知道溶洞是如何形成的吗？ 

    连州地下河是典型的喀斯特地貌地下暗河溶洞。

喀斯特是前南斯拉夫西北部的石灰岩高原地名，19世纪末，南斯拉夫学者司威杰用喀斯特一词作为石灰岩地区一系列作用过程现象的总称，后来我国建议把“喀斯特”一词改为“岩溶”。所以喀斯特地貌也称岩溶地貌。中国是世界上对喀斯特地貌研究最早的国家，早在晋代就有记载，以明朝时期的《徐霞客游记》记载得最为详尽。

    Caves come in a myriad of shapes and colors, showcasing the wonders of nature. But do you know how caves are formed?

    The Lianzhou Underground River is a typical karst landform underground river and cave.

    Karst is the name of a limestone plateau in the northwest of the former Yugoslavia. At the end of the 19th century, the Yugoslav scholar J.Cvijic used the term "karst" as a general term for a series of processes and phenomena in the limestone area. Later,China suggested changing the term "karst" to "karst". So karst landform is also called karst landform. China is the earliest country in the world to study karst landforms. As early as the Jin Dynasty, there were records of it, and the "Xu Xiake's Travel Diaries" of the Ming Dynasty provided the most detailed information.
