| 摘 要： | 地球外部重力场由地球内部物质分布所决定，由于地壳与地幔、岩石圈与软流圈存在着较大的物性差异，利用重力资料可以确定莫霍面和岩石圈底面深度。基于上述结论，利用ＯＳＵ９１全球重力位模型数据进行了反演，计算结果表明，地壳和岩石圈厚度与地形相关，大陆地壳、岩石圈较厚，海洋则相反。

| Abstract: | The earth outer gravity field depends on the interior mass density distribution of the earth. Because physical character differences exist between crust and mantle, lithosphere and asthenosphere, it is possible to determine the depth of Moho and lithospheric bottoom interfaces by using gravity data. The crustal and lithospheric thickness are inversed by using the data of OSU91 gravity modle in this paper. The results show that the crustal and lithospheric thickness are relative with global surface tectonics. |
