| 摘 要： | 高精度地磁模型能详尽地反映地磁场在地面上的分布,具有较高的模型分辨率。在资源勘探、地质结构、地震火山预警、地磁导航等应用领域有重要意义。简要介绍了部分近年来国际高精度地壳磁场模型,通过分析发现NGDC-720模型较以往低阶模型精度有明显改善,并据此模型绘制了东海以及毗邻海域三分量磁异常分布,发现该模型能与地质结构相吻合,能给相关应用领域提供更多的信息和保障。

| Abstract: | In allusion to lithospheric magnetic field,a high-resolution geomagnetic model always exhaustively reflects the distribution of the geomagnetic field at geoid altitude,and it has a high resolution.This field is essential to resource exploration,geological structure,earlywarning of earthquake and volcano,geomagnetic navigation.In this paper,some high-resolution geomagnetic models are briefly introduced.The NGDC-720 model is analyzed and compared with the low-order ones.The result shows that the NGDC-720 model has a higher precision.The author draws the three-weight anomaly maps in east-sea of China and adjacent areas with the above data.The results from the maps have more common with geological structure.Consequently,the more guarantee and communication are provided in correlative application scopes. |
