利用东海地区的重力资料 ,并参考在该地区进行的地震测深结果 ,应用线性公式估算了研究区的地壳厚度 ,分析了研究区地壳结构特征 ,根据与中国东部地球物理场、地壳结构的对比 ,指出东海大陆架地区应是中国大陆的自然延伸 .对冲绳海槽的地壳性质进行了探讨 ,指出冲绳海槽应该为东海大陆架的自然终结 .
Based on the gravity data in the East China Sea and the seismic sounding results in the area, the crustal thickness of the study area is estimated by linear formula and the crustal structure characteristics of the study area are analyzed. Based on the comparison with the geophysical field and crustal structure in eastern China , Pointing out that the continental shelf area in the East China Sea should be a natural extension of the Chinese mainland and discussed the crustal nature of the Okinawa Trough, pointing out that the Okinawa Trough should be the natural end of the continental shelf of the East China Sea.
