摘要
The paper defines the resource system of Leye geological relics as 7 landscape types, 10 landscape fields, 19 landscape segments, 32 landscape cells and numerous typical landscape entities. On the basis of analysis and investigation about the background of the formation of scenic spots, the formation of scenery in Leye is categorized into four epochs in terms of different geological stages and the typical karst landform formed during the specific geological stage, namely, the epoch of Fengcong, the epoch of underground river and cave, the epoch of Tiankeng and the epoch of modern karst. During the four epochs, as the formation of scenery in Leye is macro-controlled and affected by the cyclical evolution of tectonic movement which involves multiple cycles from tremendously strong to relatively strong, to feeble, finally to stable, and specifically by climatic factors, formation lithology and the process of karst, different “Tectonic-Surface-Climate” responses.
