本文基于分形理论和RS技术,对遥感影像上所提取出来的线性构造信息进行定量分析、空间展布特征与铀矿富集关系的研究,并且简要阐述线性构造遥感影像机理和断裂构造信息的解译与提取。通过研究表明,下庄矿田断裂构造在0.3125—5km尺度范围内具有自相似性和分形特征,相关系数均超过0.98,并且在该尺度范围内断裂构造空间展布出现两个分形关系,在0.3125—1km尺度范围内分数维D1=1.0693,在1.25—4km尺度范围内D2=1.7469。这进一步表明该区断裂构造具有多重分形分布特征。其断裂构造展布在0.3125—1km小尺度范围内较小的分维值D1表明该区还有进一步勘探前景。

Linear Structure information extracted from TM image were studied by quantitative analysis of the relation Of their spetial distribution features and uranium mine concentration based on fractal theory and RS in the paper. It explained the mechanism of linear structure on TM Image and interpreted fault structures in brief. The results show that the fault structures in Xiazhuang Ore Field have self-similarity statistically and their distributional regularity is within scale range of 0. 3125-5km and all correction coefficients exceed 0. 98. It can be regarded as two fractal relation and the fractal dimension within scale range of 0. 3125-1km is D1 = 1. 0693, within scale range 1.25-1km is D2 = 1. 7469. Farther, It shows that fault structures have multi- fractal character in the Xiazhuang Orefield. It indicates that the region has farther perspective to explore where the structures within O. 3125-1km with minor value of fractal dimension.
