摘要: 路南石林是多期喀斯特过程的产物。根据石林与地层的接触关系、岩性变化、古风化壳、溶蚀率、钙华样年龄，确定了路南石林发育的多期性：前玄武岩期（晚二叠世早期）、前路南古湖期（三叠纪—古新世）、路南古湖期（始新世—渐新世）、高原—巴江期（中上新世—更新世）。高原—巴江期是剑状石林的主要发育时期。各期石林空间上的分离与重叠是路南石林喀斯特景观多样性的原因。
Abstract: The Lunan Stone forest is the product of multi stage karstification In light of the contact relationships between the stone forest and strata,lithologic change,dissolution rate,paleoweathering crust and ages of the travertine samples,the stages of development of the Lunan stone forest have been determined;they are the pre basalt stage（early Late Permian）,pre Lunan Ancient Lake stage（Triassic Paleocene）,Lunan Ancient Lake stage （Eocene Oligocene） and Plateau Bajiang River stage （middle Pliocene Pleistocene） The last stage was the principal development stage of the pinnacle stone forest The separation and superimposition of various stages of stone forest were the cause for the diversification of the karst landscapes of the Lunan stone forest
