摘　　要：浊积岩综合体、浊积岩系、浊积岩阶、浊积岩亚阶、浊积岩层的浊流沉积体系概念框架的建立,使不同地区海相浊流沉积之间可以进行精确的时空对比。当把该概念框架引入到陆相箕状断陷湖盆的缓坡一侧的浊流沉积中时,发现其与海相浊流沉积之间在沉积演化的控制因素方面存在较大的不一致性,其中浊积岩系、浊积岩阶的形成在海相浊流沉积中主要受控于相对海平面变化,而在陆相断陷湖盆中则分别受控于构造沉降、碎屑物质的供应速率的变化。The conceptual framework establishment of turbidite depositional system, which includes turbidite complex, turbidite system, turbidite stage and sub-stage as well as turbidite beds, facilitates temporal and physical correlation exactly among marine turbidite deposits in different areas. When the framework is introduced into the halfgraben-like fault lacustrine basin, the continental turbidite deposit of its side of ramp is found to be more different than the marine turbidite deposit in terms of control factors of sedimentary evolution. The turbidite system and turbidite stage of the marine deposit are mainly controlled by relative change of sea level, while those of the continental fault lacustrine basin controlled by the tectonic subsidence and the change of debris flux, respectively.
