【摘要】 苏北东部海域辐射沙洲以往仅侧重于外动力方面的研究 ,这里提出开展内动力与外动力同步研究的新思路 ,指出两者的结合点是旋扭运动 ,要在以往外动力研究的基础上 ,加强地震震中研究、地形变监测、地应力实测等方面内容 ,以确定该区不同层圈、不同介质条件下是否存在同一的旋扭运动。上述思路的实施 ,有利于地理学与地质学研究的沟通和溶合 ,同时提出地震往往伴随旋扭现象的事实 ,丰富了地震学的研究内容 ,其研究成果将为多方面的开发幅射沙洲提供基础资料更多还原

【Abstract】 More emphases were put on outer dynamics of the radial sand ridges in the past studies.This paper points out a new idea of simultaneous study on both inner and outer dynamics.The rotation between crust and ocean is considered as their connection point.Further study is needed for epicenters,crustal deformation and crustal stress,so that we can determine the existence of the same rotation in different layers and in different medium conditions of the area.Results of the proposed study will help us a lot understand the connection between geographic and geologic studies.At the same time,the fact that rotation situation generally occurs following an earthquake will expand the content of seismological research,and will also provide some basic data for comprehensive exploration of the radial sand ridges in north Jiangsu.更多还原
