江汉—洞庭盆地岩石圈构造特征及地壳稳定性浅析

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。

The Charaeteristics of Lithospheric Structure beneath the Jianghan Dongting Basin and a Simple Analysis about Crustal Stability

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.
