云南黎明丹霞地貌景观特征及成因研究

Study on the Features and Formation of Danxia Geomorphologic Landscape in Liming Yunnan

分析了云南黎明地区丹霞地貌发育地区的景观特征,从地质学的角度出发,分析典型丹霞地貌景观的成景地质条件,探讨景观的地因,总结景观的成景过程.研究认为:黎明丹霞地貌具有自身独特的特征,岩性和构造是独特丹霞地貌景观形成的根本原因;峰林景观受岩层厚度、节理发育程度、交错层理控制;丹霞峰林或赤壁上的"变色瀑布"是裂面或层面之间岩层水渗出沿壁下淌的结果;龟裂纹景观形成严格受岩性和节理构造控制,其发育经过了成景初期、成景中期、成景晚期三个阶段.

The geomorphologic landscapes are discriminated in Liming Yunnan. Based on geology, the geologic conditions, geologic formation and formation stages of Danxia landform landscape are studied. Conclusions are achieved :Danxia geomorphologic landscape in Liming area has peculiar features under the control of structures and lithologicl; Danxia mesas vary with the conditions of thickness of rock formation, jointing development and cross-stratification;'Color waterfall'on cliff is the result of water exuding from crevices;Scenic view of tortoises hell cracks is thorollghly controlled by lithological characters and jointing structures, and its formation is divided into three stages:primary stage,ent stage and final stage.
