Abstract：Kongshan Baiyun Cave developed mostly in thick oolitic limestone strata of the Middle Cambrian Zhangxia Formation.By means of the observation and analysis on cave texture,morphology and sedimentary characteristics of the Baiyun Cave，along with areal geological evolution and palaeoclimate evolution，it was indicated that（1）Baiyun Cave system comprised three layer caves.The upper layer presented large hall-like caves.The middle layer and the lower layer were narrow corridors.The distribution of the caves was controlled by NNW，NE and nearly EW faults.（2）Development of the cave shape and size not only related with lithology and structures，but also depended on tectonic stability and coupling climatic conditions in the forming periods of the caves.The layered distribution of the caves was the result of intermittent tectonic uplift.（3）The karst cave deposition landscapes are various.Therefore，reticular helictite made of the capillary water deposition and hosta to aquarius formed from collaborative deposition are very rare.(4）Baiyun Cave was damaged repeatedly by tectonic movements during its development.Nowadays，Baiyun Cave rock is fractured and the cave structural stability is not good.So researches on geomorphic features, sedimentary characteristics and their influencing factors of Baiyun Cave are important to predicting the future change and protecting cave tourism resources.
