| 摘 要： | 计算巴彦浩特盆地航磁异常的分维数, 对计算出的分维数绘制等值线图, 并根据分形特征对该地区的火成岩进行划分, 得到了以往直接对航磁异常图进行推断解释所不能得到的良好地质效果。最后讨论如何选取最佳窗口和最佳网格来计算分维数, 并对此提出了2个经验。

| Abstract: | On the basis of calculating the fractal dimension of the aeromagnetic data from Bayan Hot basin, a fractal contour map was drawn and the distribution of igneous rocks was deduced according to the fractal characteristics. From the map, the relatively good geological result which cannot be obtained from the aeromagnetic contour map has been attained. In the end of this paper, the selection of the optimal window and the optimal grid for calculating fractal dimension is discussed, and some experience is advanced. |
