摘要

通过卫星测高重力数据与船载重力测量结果进行空间分辨率对比、海陆重力异常接图, 以及我国南黄海海域卫星测高重力对沉积盆地与隐伏构造解释的应用试验, 对现代国内外卫星测高重力数据获取与重力异常分辨能力进行了分析, 指出了现代卫星测高重力异常的精度达到4×10^-5m/s²左右, 可以满足1∶100万比例尺的海洋重力调查与辅助前期资源勘查的需要, 并对卫星测高重力技术的应用提出了建议。

Abstract：

Modern satellite altimetric gravity (SAG) is studied in this paper on the basis of a comparison with measured data on spatial resolution, on-shore and off-shore joint mapping, and interpretation work in the South Yellow Sea. It is pointed out that resolution of high resolution satellite altimetric gravity data can now achieve 4×10^-5m/s²l or so and thus can be used in 1∶1 million regional marine gravity survey. Suggestions on marine gravity work for marine oil and gas resources and geological survey in China are also put forward in this paper.

Key words： Qiangtang Plateau Duobuza copper ore district and its periphery regional overall geochemical survey test survey prospecting prediction
