摘　　要：为建立地震反射特征和沉积环境的响应关系，应用综合评判方法，以松辽盆地乌裕尔地区的相位、振幅、层速度等地震反射特征和岩性指标作为沉积环境的判别指标，介绍了判别沉积环境的计算方法。依据计算结果，绘制了研究区沉积环境判别图，通过与该区沉积环境分区图的对比分析，探讨了各种评判指标对沉积环境的贡献大小以及沉积环境判别的误判率，从而探讨了地震反射特征与沉积环境之间的对应关系，验证了此判别方法的可行性。The purpose is to discuss the corresponding relation between seismic relfectiion fea ture and sedimentary environment. By means of comprehensive identifying method,the phase,amplitude,interval velocity,and lithology of Wuyuer region in Songliao Basin are regarded as the identifying parameters of sedimentary environment. A calculating method is also introduced. According to the result , the figure of sedimentary environ ment identification is drawn. By analysis on the figure of sedimentary area,the contri bution of every parameter to sedimentary environment and the error percentage are dis cussed.The corresponding relation between seismic reflection feature and sedimentary environment is also discussed, the feasibility of this method is proved.
