| 摘 要： | 选用中国21个地磁基准台站2011年的绝对子夜均值数据,分析D、H、Z分量年变化量空间分布特征。结果显示,各分量年变化量等值线分布比较均匀,其中:D分量年变化量等值线大致沿南北向分布,零经线附近台站年变化量较小;H分量年变化量等值线大致呈U型分布,且中心点位于甘肃省;Z分量年变化量等值线沿纬线方向,随纬度减小而增大。

| Abstract: | This paper selected the absolute geomagnetic midnight average of D, H, Z component in 2011, Z components, and analysed spatial distribution of annual variations of each component absolute geomagnetic midnight average. The results showed that the spatial distribution of the annual variation contour of each component is more uniform, D component annual variation contour roughly along the north-south direction, and is smaller variation near zero longitude; H component annual variation contour is roughly U distribution,and center U in Gansu Province; Z component annual variation contour along the latitude direction, and increases with decreasing latitude. |
