摘　　要：讨论了目前常用的几种国家坐标与地方坐标的转换方法,并对它们的效果进行了比较分析,得出了一些有益结论。To satisfy the need of project construction, we always want to build local independent coordinate system, to make the using of surveying and mapping products conveniently, we hope that the production of local coordinate system ~ and that of national coordinate system could convert to each other, Several conversion methods in common use has been discussed in the test, their effects have been compared and analyzed too. Some useful conclusions have been given.

关 键 词：抵偿投影面 地方椭球 坐标转换
