介绍了2008年在喀什—乌恰地区32个测点的流动地磁测量数据的处理方法。利用该数据建立了喀什—乌恰地区地磁场的曲面样条模型,绘制了区域地磁基本场分布图。以2005年中国地磁场球冠谐模型为参考场剥离了岩石圈磁场,绘制了喀什—乌恰地区岩石圈磁场局部异常分布图。表明岩石圈磁场局部异常与测区内地震在空间上有一定的对应关系。
The method of processing geomagnetic survey data of 32 measuring points in Kashgar - Wuqia area in 2008 was introduced. Using this data, a surface spline model of geomagnetic field in Kashgar-Wuqia area was established, and the basic geomagnetic field distribution map of the region was drawn. Taking lithospheric harmonic model of China’s geomagnetic field in 2005 as reference field, the lithospheric magnetic field was peeled off and the local anomaly distribution of lithospheric magnetic field in Kashi-Wuqia area was plotted. It shows that the lithospheric magnetic field has a certain spatial correspondence with the local earthquake in the survey area.
