中国海陆及邻域布格重力异常编图研究

Bouguer anomaly compilation study of China and the adjacent regions

收集、整理了中国海陆及周边22个国家陆地实测重力资料和海域卫星测高重力资料,建立了覆盖2672万平方千米的重力异常数据集.研究解决了高精度海洋卫星测高重力数据与陆地实测重力数据的海陆异常联编、不同来源和背景重力数据之间的调平以及大区域重力异常编图表达等技术问题.采用当代规范、先进的数据拼接与编图技术编制了中国海陆及邻域1500万布格重力异常图,并进一步结合区域地质构造认识,划分了38个重力异常区.

The compilation techniques of the 1 ： 5 million Bouguer anomaly map of China and 22 adjacent countries and regions covering some 26. 27 million square kilometers are introduced in the paper, including standard data coordination, data and anomaly combination of offshore satellite altimetry gravity data with onshore observed gravity grids, and modern techniques for gravity anomaly mapping illustration. And 38 anomaly feature regions are delineated which is helpful to regional geological structure study.
