摘要
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 elevation of neotectonic movement and climatic viberation are the main influencing factors of the evolution of Jinshajiang valley in the,Leibo Region;these two factors are clearly coupled,and are also correlated to the development of Karst caves and landslides in this area. The karst caves and landslides developed in the warm wet periods. In the cold dry periods,cliff and undergroud river deposition formed when the river made vertical erosion. Frequent intermittent elevation of neotectonic movement and climate viberation caused the development of multiperiod landslides and multistoried karst caves,but in another hand,it limited the size of the karst caves.
