中文摘要：
阐述了采用Stokes方法或Molodensky方法难以确定全球cm级大地水准面的理由。提出了一种实现具有分辨率1°×1°的全球cm级大地水准面的理论方案，并给出了实施步骤，其基本前提是给定全球具有分辨率为1°×1°的mGal的引力位模型以及精度较高的地表浅层密度分布。
英文摘要：
It is declared that the global geoid with one centimeter level accuracy is difficult to be realized using Stokes or Molodensky approach. Under the assumption that the density distribution of the shallow mass layer bounded by 偏dΩ and a closed reference surface 偏dГ that lies under the geoid 偏dG as well as the the global 1°× 1° gravitational potential field model is given ; an approach for determining the global 1°× 1° geoid with centimeter-level accuracy is proposed; and its actual realization procedure is provided.
