新构造运动的间歇性上升和气候的冷暖干湿波动是雷波地区金沙江河谷演化的主要影响因素,且两者间具有明显的耦合性,与河谷区的滑坡、岩溶洞穴发育关系密切相关。暖湿期发育滑坡和岩溶洞穴,干冷期河谷下切,形成陡坎及洞穴内的地下河流相堆积。频繁的间歇性新构造上升运动及气候冷暖波动导致多期滑坡和多层洞穴发育,但制约了洞穴规模的发展。
The intermittent increase of neotectonic movement and climate warming, cold and dry fluctuation are the main influencing factors of the evolution of the Jinsha River valley in Leibo, and have obvious coupling between them. They are closely related to the development of landslides and karst caves in the valley. Landslides and karst caves are developed during the warm and wet periods, and the river valleys are cut under dry and cold conditions, resulting in the formation of scarps and accumulation of underground river facies within caves. Frequent intermittent neotectonic uplift and climatic fluctuations in climate lead to the development of multi-stage landslides and multi-layered caves, but this has restricted the development of caves.
