摘　　要：对我国当前常用坐标系统进行介绍,并对不同坐标系统之间坐标转换原理进行介绍。通过MATLAB编写基于最小二乘法的布尔沙七参数转换模型,并对1980西安坐标系统和2000国家大地坐标系(China Geodetic Coordinate System 2000,CGCS2000)坐标进行转换实验,结果表明:该方法转换的点位误差均小于5cm,可满足一般工程使用。The current common coordinate system in our county and the transformation methods of these two coordinate systems were introduced.The order of bursa model was compiled by MATLA B and the parameter calculation based on the least square method.The experiment of coordinate transformation between 1980 Xi'an coordinate system and China Geodetic Coordinate System 2000(CGCS2000)shows that the point position errors are less than 5cm and can be used in general engineering.
