基于Airy-Hesikannen均衡模型的莫霍面反演

Inverse of the mohorovicic's surface based on airy-hesikannen's isostatic model

本文主要针对利用Airy -Hesikannen均衡假说构制不同地形区域包括平原、丘陵、和小、中、大、特大山区以及高原地区的重力异常时 ,其均衡模型参数 -地壳正常厚度在任何地区均不变而导致的均衡归算精度不高的缺陷 ,推导了基于Airy -Hesikannen均衡模型反演莫霍面的公式 ,并进行了相应的数值检验 ,根据此公式可统计出不同地形区域的均衡模型参数 。

Consistent parameter of Airy-Hesikannen isostatic model of all kinds of terrains (including plains,hills,mountains with different heights and plateaus) leads to low accuracy of isostatic reduction in the calculation of gravity anomaly. Formalae of inverse of the (Mohorovicic's) surface were derived and numerical tests were made. According to the formalae,the parameter of isostatic model could be determined so as to improve the accuracy of calculating isostatic anomaly.
