摘　　要：采用2000国家大地坐标系(CGCS2000)构建独立坐标系是我国新时期城市规划扩建、城乡统筹发展的新需求。本文结合项目实例,通过对投影变形计算及独立坐标系常用建立方法的深入分析与研究,论述了基于CGCS2000独立坐标系构建方法,充分利用地心坐标系高精度的优点实现独立坐标系构建及成果转换,编制了“投影变形图形化分析程序”,使变形分析更加直观、准确、快捷。The construction of an independent coordinate system based on CGCS2000(2000 National Geodetic Coordinate System)is a new requirement for urban planning and expansion,as well as urban-rural coordinated development in China′s new era.Combining project examples,this study conducts in-depth analysis and research on projection deformation calculation and commonly used methods for establishing independent coordinate systems.It demonstrates a method for constructing independent coordinate systems based on CGCS2000,leveraging the high-precision advantages of the geocentric coordinate system to enable independent coordinate system creation and result conversion.Furthermore,this study develops a graphical analysis program for projection deformation to make deformation analysis more intuitive,accurate,and fast.
