摘　　要：本文运用分形理论对下庄地区铀矿床(矿点)的空间分布进行了研究。结果表明,铀矿床(矿点)的空间分布具有统计自相似性的分形特征,分数维可以用来定量描述铀矿床(矿点)的分布规律;应用盒计维数的统计方法计算了铀矿床(矿点)空间分布的分数维D值,并对西、中、东成矿活动区的分数维D值进行了比较,探讨了分数维D值的地质意义。实际资料计算结果显示网格数与标度之间具很好的相关性,其相关系数均达0.98以上。Fractal theory is utilized to study spatial distribution features of uranium deposits in Xiazhuang region. The results show that the spatial distribution of uranium deposits has self-similarity statistically and the distributional regularity of uranium diposits can be quantitatively described with fractal dimension. The fractal demension value of spatial distribution of uranium deposits are calculated with counting box method. The dimention value of different metallogenic regions are carnpared. The result shows that the number of box correlates well to the scale with a correlation coeffient of more than 0. 98.
