| 摘 要： | 高精度局部大地水准面将为测绘学、地球物理、地球动力学及海洋学等相关学科的发展和应用提供重要的基础地球空间信息。GPS技术结合高精度大地水准面模型可应用于取代传统的高程测量(如三角高程测量和低等级水准测量)，这是当前精化我国省市级大地水准面在测绘领域的主要目的之一。在总结和分析我国目前省市级大地水准面精化的现状、技术模式及特点的基础上，提出了今后精化我国省市级大地水准面的若干建议。

| Abstract: | The precise local geoid model will provide the important fundamental geo information not only for surveying and mapping but also for studying some related problems of geophysics, oceanography and geodynamics. GPS technique, along with the high precision local geoid, can be employed to substitute the traditional (height survey), such as trigonometric heighting and low precision leveling. This is one of the principal objective of refining the local provincial (municipal) geoid for geodesy and geomatics in China. The present situations, technical modes and characteristics are first analyzed for the precise determination of the local provincial (municipal) geoid in China, and then some suggestions are presented for refining the local provincial (municipal) geoid in future. |
