全球扰动场源的研究及其大地构造意义

作为大地重力学反问题研究的实际应用，本文计算了全球扰动场源．在参数选择、赋值模式上，首先考虑到地球的成层结构与密度异常分布．研究表明，地球内部物质分布的不均一性主要体现在岩石层块体内部，并一直延深到幔核边界；地壳中的构造活动与地球内部物质分布状态相关．从大地构造学的角度，分析对比讨论了扰动场源所揭示的地球深部地质作用机理．

STUDY ON THE RESOURCE OF ANOMALOUS GRAVITY FIELD OF THE EARTH AND ITS TECTON IC SIGNIFICANCE

As applied the inverse gravimetric problem to practice, this paper accounted the resource of anomalous gravity field of the Earth. First, we think of the tectosphere and distrbution of the density in the earth, while electing the parameters and evaluation mode. The computating results depths rigorous reflected the distribution of the material in the inter texture of the earth. The results directed that the inhomogeneity of material distribution in the Earth mainly reflect in the inner lithosphere and extend to the boundary between mantle and core of the earth. The activity of the tectonices in the crust is related to the material distribution of the inner earth. From the view of geotectonics, this paper also discussed the dynamics of the deep geologic processe displayed by the resource of anomalous gravity field of the Earth.
