摘　　要：讨论了参心系下的地形图转换到2000国家大地坐标系(CGCS2000)下的方法。用全国大致有代表性的区域进行实验,证明所采用的方法完全能满足国家基本比例尺地形图的精度要求。China Geodetic Coordinate System 2000（CGCS2000） was formally released to be used in China on July 1 in 2008.So all products related to reference ellipsoid should be transferred to CGCS2000.We main discuss how to transfer maps from reference coordinate system to CGCS2000 with 3D four parameter coordinate transformation model.In order to test the proposed method,the experimental areas which could stand for characters of whole country were chosen.Computation and analysis show that the recommended method can fully meet the accuracy of basic scale map transformation in China,and is better than the existed methods while it is simple and convenient.

关 键 词：2000国家大地坐标系 三维4参数转换模型 地图转换
