CGCS2000坐标系对现有地质成果的影响

Impacts of CGCS2000 on Existing Geological Results

随着空间技术的快速发展,新一代地心坐标系—2000国家大地坐标系(简称CGCS2000坐标系)于2008年7月1日正式启用,未来几年将逐步完成1954年北京坐标系和1980年西安坐标系向CGCS2000坐标系的过渡与转换。为了有效分析CGCS2000坐标系对现有地质、物化探成果的影响,本文在概述CGCS2000坐标系的定义和实现的基础上,通过采集数据进行实证分析,对CGCS2000坐标系在地质调查中的使用和现有地质成果的转换工作提出了建议。

With the fast development of technology, a new generation of geocentric coordinate system -- China Geodetic Coordinate System 2000 （CGCS2000） was officially put into use on July 1,2008, and it would transform and substitute 1954 Beijing Coordinate System and 1980 Xi＇an Coordinate System gradu- ally. To analyze the impacts of CGCS2000 on the existing geological,geophysical and geochemical results, this paper reviews the definition and implementation of CGCS2000, collects data to make an empirical analysis,and finally puts forward suggestions on the application of CGCS2000 to geologic survey and the trans- formation work of the existing geological results.
