  1998年国土资源部在中国广西壮族自治区百色地区乐业县进行土地资源调查时,发现一种世界罕见的地质奇观^喀斯特漏斗群,又称乐业天坑群,是我国最大的天坑群,也是世界上最大的天坑群。 该地区为典型的喀斯特地貌(即岩溶地貌),降水量大,为地下洞穴的发育提供了良好条件。 该处占地约20平方千米。初步已发现有大石围、白洞、风岩洞、穿洞等20多个天坑。“天坑”四周皆被刀削似的悬崖绝壁所围,形成一夺巨大的竖井,底部是人类从未涉足过的几十万平方米的原始森林,并有地下河相通。森林中有大量珍贵的动植物品种。其地下原始森林面积为世界第一,深度位居世界第二,容积居世界第三,具有极高的科研价值。In 1998, the Ministry of land and resources in the Guangxi Zhuang Autonomous Region area of Baise China Leye County land resources survey, found a rare geological wonders of the world ^ Karst funnel group, also known as the music industry Tiankeng group, is China's largest Tiankeng group, Tiankeng group is the world's largest. The area is a typical Karst landform (topography),precipitation, underground cave development provides a good condition. Itcovers an area of about 20 square kilometers. Preliminary has found Dashiwei,white hole, wind cave and piercings 20 tiankeng. "Tiankeng" round was cuttinglike cliff surrounded, forming a duo huge shaft, the bottom is the humanity has never visited hundreds of thousands of square metres of the primeval forest, andis communicated with the underground river. There are a large number of rarespecies of plants and animals in the forest. The underground original forest area is the first in the world, the depth of the second largest in the world, volume ranks third in the world, with high value of scientific research.
