| 摘 要： | 笔者将分形几何学的原理和方法，应用于湘中地区断裂体系的二维平面分布特征研究，发现在研究的标度范围内（ｒ约２～８０ｋｍ）不仅具有统计自相似性，并且同一地区，不同分区具有不同的分维值Ｄ，分维值分布特征为东南区分维值高于西北区分维值，将本区断裂体系的这种分维值分布特征与锑矿床分布特征对比，可发现锑矿床（点）产出较多，矿床规模较大的地区，其分维值较大。

| Abstract: | The principles and methods of fractal geometry are applied to the study of fractal characteristics of two-dimensional fault systems in central Hunan. The authors find that these fault systems not only possess statistical self-similar characteristics in the scale extent studied (r=0. 1~4 cm, about 2-80 km) but also have different D values of fractal dimension in different subranges of the same area. The distribution of D values of fractal dimension in sub-ranges shows that the D value in the southeast sub-range is slightly higher than that in the northwest subrange. Comparison of the distribution characteristics of D values with those of antimony deposits in central Hunan reveals that the more and larger the antimony deposits are the higher the D value will be, given the same spacial location. |
