断裂分布空间结构的信息维Ｄ１避免了容量维Ｄ０的缺陷，考虑了每条断裂对信息维所作的贡献，从新的角度反映了断裂分布的空间结构特征。计算结果表明湘中盆地北部信息维为１．７９２，南部信息维为１．６８５。南北两部分分属于信息维不同的两个自相似系统。结合区内锑矿床的分布特征，可发现信息维的大小对成矿流体的运移和矿床定位有一定的指示作用，锑矿（点）产出较多、矿床储量较大的地区，其信息维值较大。
The information dimension D1 of the fracture distribution space structure avoids the defect of capacity dimension D0, considers the contribution of each fracture to the information dimension, and reflects the spatial structure of the fracture distribution from a new perspective. The calculation results show that the information dimension in the northern part of the Central Hunan Basin is 1.792 and the information dimension in the south is 1.685. The two parts belong to two self-similar systems with different information dimensions. Combining with the distribution characteristics of antimony deposits in the area, it can be found that the size of the information dimension has some indication to the migration of ore-forming fluids and ore deposits, the areas with more antimony ore (ore spots) and larger deposits of ore deposits The value of the larger dimension.
