摘　　要：利用不同的解算软件,采用三维七参坐标转换模型和二维四参坐标转换模型,把1980西安坐标系成果转换成2000坐标系成果,利用大量检核点进行坐标转换成果精度检查,并对检查点点位精度做了详细的统计、分析;不仅阐述坐标转换方法和要求,而且得出在2种坐标转换模型应用的条件与要求。By using different computing softwares, using three--dimensional seven--parameter coordinate transformation model and two--dimensional coordinate transformation model, the results gained by the 1980 Xi＇an coordinate system can be transformed to the results of the 2000 coordinate system. Accuracy of checking points have been statisticed and analyzed. Not only the coordinate transformation methods and re- quirements have been introduced, hut also the conditions and requirements of the application of two models have been gained as weill.
