摘要
用对数径向功率谱方法计算了盆地区域重磁异常的分维值，将不同地球物理异常场的分维值作为研究盆地深层构造的参数，同时，将分维值作复合处理，得到复合后的盆地多源地球物理异常场的分维异常图。最后，分析了复合分维异常图在研究盆地深层构造中的作用和效果，探讨了这种自仿射分维值大于３的问题。
In this paper,the fractal values of regional gravity and magnetic anomalies of basin arecalculated by the method of logarithmic radiai power spectrum。The fractal values of differentgeophysical anomalous fields are used as the parameters to investigate the deep～seated structure of basin. At the same time,the fractal values are compounded,and then the compoudingfractal anomaly map of multi-source geophysical anomalous fields of basin is obtained. Final-ly,we have analysed the action and effect of compounding fractal anomaly map on the re-search about the deep-seated structure of basin and discussed the problem in which the selfaffine fractal value is greater than 3。
