摘　　要：利用地球物理场的各种成果资料，与地质、地震资料相结合，对江汉—洞庭盆地的地壳及岩石圈中下层构造特征进行分析，得到了一些有意义的结果，例如，根据ＷＤＭ—８９地球重力场模型位系数所计算的高阶窗卫星重力异常，不仅能较好地反映研究区岩石圈的构造特征，且与该地区中强地震的分布有一定的对应关系。Using various geophysical results and combining them with geological and seismic informations,this paper has analyzed the characteristics of the structure of middle lower parts of crust and lithosphere be-neath the Jianghan Dongting basin and obtained some useful results.For example,the high-order satellite gravitg anomalies computed by Potential coefficient of earth gravity field model WDM 89 not only well reflect the features of lithospheric strucure in this area,but also have a corresponding relation with the earthquakes of medium intensities.
