摘　　要：简要介绍了2000国家大地坐标系及其框架,分析了1954年北京坐标系在区域重力调查工作中存在的问题,并根据国家测绘局对于推广使用CGCS2000的政策要求,就区域重力调查工作中推广使用可能面临的问题进行了详细的论述,并探讨性地提出了在过渡期逐步实施CGCS2000坐标系的解决方案及建议。应极积采取有效方法,就有关CGCS2000坐标系在区域重力调查工作中的技术问题进行详细探讨和研究,进而开发管理系统,推进区域重力调查技术进步。This paper briefly introduces China geodetic coordinate system 2000 and frame,and also analyzes the influence of Beijing 54 coordinate system on regional gravity survey.On the basis of policy that State Bureau of Surveying and Mapping requires to promote CGCS2000,this paper discusses the new problems on regional gravity survey,and puts forward the solution and suggestion on implementation of CGCS2000.It is proposed that some active and effective approaches should be taken to apply the relevant CGCS2000 coordinates to the work of the regional gravity survey in detailed the technical aspects of exploration and research,and the management system should be developed to promote the regional gravity survey of technological progress.
