摘　　要：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。On the basis of the geological and geophysical analysis; the authors of this paper concluded that LST is the output of half-dry-hot climate when the rate of the subsidence was rather higher; TST is the mutual consequence of both the warm-wet climate and transgressive supply of the sea with rather higer rate of the tectonic subsidence, among them the transgressive supply is the major factor; HST developed in wet-hot climate when the tectonic subsidence maintain eqilibrium with the sediments acommodation; RST developed when the rate of sediments acommodation and the ratio of which and the rate of the tectonic subsidence are rather higer with the climate which turn into dry-hot from wet-hot. This conclusion provide the options for the developed regulation of the sequence stratigraphy in this area.
