摘　　要：在具体的测量实践中,需要在1954北京坐标系、新1954北京坐标系、1980国家大地坐标系、WGS-84大地坐标系和2000国家大地坐标系之间进行坐标转换,以进行数据对比和精度分析。文中使用MATLAB软件对布尔莎七参数坐标转换模型和迭代的七参数坐标转换模型进行了编程实现,通过比较迭代的七参数坐标转换模型与普通布尔莎七参数坐标转换模型的坐标转换精度,得到了普通七参数坐标转换模型和迭代的七参数坐标转换模型的适用条件,为具体工程测量实践提供了参考。In concrete survey engineering work,coordinate transformations among 1954 Beijing Coordinate System,1954 New Beijing Coordinate System,1980 National Geodetic Coordinate System,1984 World GeodeticSystem(WGS-1984)and 2000 National Geodetic Coordinate System are needed for data matching and precision analysis.In this paper,the Bursa seven-parameter coordinate transformation model and an iterative seven-parameter coordinate transformation model are implemented by programming with MATLAB software.From precision checks of coordinate transformations between two models,the application condition of general Bursa seven-parameter coordinate transformation model and iterative seven-parameter coordinate transformation model is concluded,and can provide reference in survey engineering practice.
