摘要
石林是一种巨型石牙类型。在赤道热带巴布亚新几内亚和沙捞越等地的类似形态，称“针（剑）状喀斯特”。纬度较低的路南石林是处在低海拔时古热带环境下形成的。在热带强烈的“双重剥蚀作用”，尤其在土下溶蚀作用下，本区同时发生夷平作用，形成广大的准平原。在上新世，特别中更新世以后，该区急剧抬升，形成高原，石林过程终止，向剥露与瓦解过程发展。高原上石林及其原野是气候变化、新构造运动和云南高原演化的证据。
The stone forest is a type of huge karren forms.It is widely distributed in Lunan County,China.The similar forms occur in equatorial zone such as Papua New Guinea,Sarawak, etc.,termed “pinnacle karst”.Obviously,the Lunan stone forest was developed in tropical paleoclimate,when the region of lower latitude was at a lower altitude.Under the tropical environment,where “dual denudation”and,especially subsoil solution were in progress,planation took place,forming a vast peneplain.After Late Neogene,particularly in Middle Pleistocene,the area rapidly uplifted and Yunnan Plateau was formed.The environment was changed and the stone forest ended. Serving as an evidence of climatic change,neotectonic movement and plateau evolution,such huge karren and vast karren field on the plateau are,consequently,rare in the world.
