松辽盆地西部斜坡区坳陷期的低位体系域是半干热气候下构造沉降速率较大时的产物；湖进体系域是构造沉降率较大、气候温湿及海侵补给的共同作用结果，其中海侵补给是主要因素，构造沉降和气候条件是基本因素；高位体系域是湿热气候下构造沉降与沉积物供给持平时的产物；湖退体系域是气候由湿热渐变干热时，沉积物供给速率及其与构造沉降速率的比值均较大时的产物
The lower system tract of the depression area in the western slope of the Songliao Basin is the product of a large tectonic subsidence rate in the semi-dry climate. The lacustrine system tract is a synergistic result of a large tectonic sedimentation rate, warm and humid climate, and transgressive recharge , Of which the transgression recharge is the main factor, and the structural subsidence and climatic conditions are the basic factors. The high-level system tract is the product of the structural subsidence and the sediment supply in the wet and hot climate. The retreat system tract is characterized by dry- The rate of material supply and its ratio to the rate of tectonic subsidence are both large
