2010.0年代蒙古地区地磁场曲面样条
|
摘要
蒙古为我国的北方重要邻国,其境内的西蒙古构造块体为我国主要地震带——南北地震带的主要北端构造.应用曲面样条(SP)方法,对蒙古地区119个野外地磁测点的观测数据进行了计算,获得2010.0年代蒙古地区地磁场空间分布,并与EMM2010.0模型给出蒙古地区地磁场空间分布进行比较.结果表明:曲面样条方法建立的蒙古地区地磁场模型与EMM给出的地磁场描述的蒙古地区各地磁要素的空间分布基本类似,但在局部地区存在一定差异,该差异在局部地区能达到±30′(I),±60′(D),±500nT(H、F、X、Y、Z).
Mongolia is an important neighbor of northern China.Western Mongolia ancient tectonic is a major structure in north of north-south tectonic earthquake zone,one important earthquake zone in China.In this paper,surfaces spline(SP)method is used to calculate the geomagnetic data on 119 sites in Mongolia on 2010.0epoch,and the geomagnetic spatial structure in Mongolia is obtained.The results show that the geomagnetic spatial distribution of magnetic components given by SP model and EMM is similar,but there are some differences in part.These differences can reach±30′for I,±60′for Dand±500nT for H,F,X,Y,Z.
