摘　　要：基于实用思路,从坐标系建立依据、点位差异、长度变形、面积变形、经济效益及社会效益等六个方面,提出了一种城市独立坐标系实用性评估体系。以中山市独立坐标系建设为例,对其开展了实用性评估。为城市独立坐标系建设与实施提供参考。This paper introduces a practicality assessment method of city independent coodinate system,which consists of construction basis,difference between coordinates,length deformation,area deformation,economic benefits and social benefits.This method is put forward based on practical ideas.This paper use Zhongshan coordinate system as an example to assess its practicality,which provides further reference for city independent coordinate systems construction in the future.
