摘　　要：以青藏直流联网工程测量坐标系统建立为例,分析了高原地区线路测量中坐标系统建立的变形因素,以及解决变形的几种方法和一些细节问题,提出了为方便高原地区线路测量中坐标系统建立的一些应用经验,以此为同行提供有益参考。Taking the establishment of Qinghai-Tibet DC interconnection project survey coordinate system as example, this article analyzed the deformation factors in the establishment of line survey coordinate system at high altitude district, some methods to reduce the deformation and some details of the issues, put forward some conclusions in the establishment of line survey coordinate system at high altitude district. We hope provide a useful reference for the peer by this article.
