摘　　要：常用的坐标转换模型,讨论了大地高的不确定性对应用Bursa模型进行坐标转换的影响。结合工程应用的实际情况,选择平面坐标转换模型对北京地方坐标与西安80坐标进行转换,转换精度满足实际需求。The common used coordinate transformation models are introduced and the ellipsoidal height errors influence in applying Bursa coordinates transformation model is discussed. Considering the engineering application and detail analysis,the two dimension transformation model in coordinate transformation between Beijing coordinate system and Xi an80 coordinate system is applied, and the results meet the engineering requirements.
