针对海拔较高的城市建立或改造独立坐标系，存在着如何选择模型及各模型对长度变形的影响等问题，通过算例对常见椭球变换和比例缩放模型进行较为全面系统的分析，归纳出常见模型在不同投影带区域、不同投影面高度对长度变形的影响差异，并得出有益的结论。

To establish or convert the independent coordinate system for cities at high altitudes, there is an issue of model selection based on its impact on length deformation.In this article, numerical experiments are carried out to comprehensively analyze common ellipsoid transformation and proportional scaling models.The discrepancies of deformation impact of the common models in different projection planes and different projection surfaces of height are summarized, and instructive conclusions are drawn.
