| 摘 要： | 山区大地电磁测深资料主要受地形与浅层电性非均匀体的共同影响，各自的影响一般很难单独分开且有效地进行校正，本文成功地确定了一种将地形与浅层电性非均匀体对大地电磁测深影响同时校正的二维反演方法－带地形的ＴＥ与ＴＭ联合二维反演方法，其具体实施过程可分为ＴＥ与ＴＭ极化曲线的识别，模型的建立和反演三步。经理论模型试算与实际资料处理表明，用该方法对山区大地电磁测深资料处理是适用的，有效的。 |

| Abstract: | The magnetotelluric sounding data in mountainous district are mainly influenced by landform and shallow inhomogeneous body. These influences can hardly be separated out respectiveIy. Authors give TE and TM joint 2-D inversion method, namely an inversion method for simultaneously removing all influences resulting from landform and shallow inhomogeneous body- This method consists of three steps: recognition of TE and TM polarization curves, model construction and inversion. Theoretical and real data results show that this method is very effective on the processing of magnetotelluric data in mountainous district. |
| Keywords: | magnetotelluric sounding landform static shift correction 2-D inversion |
