摘　　要：利用分形理论分析了德兴地区断裂构造的特点。结果表明,不仅研究区内的断裂带有自相似性,子区域也有相似现象。矿产区的分维值略高于整个研究区,铜矿区分维值高于金矿区,NW、NWW走向断裂带的分维值远高于SE走向的。说明分维值越大,越有利于矿床的形成;分维值越大的断裂走向,对矿床的产出位置控制作用越明显;地质构造复杂程度越高,分维值也越大,线性展布也越复杂。In this study, fractal dimension value was retrieved using Advanced Land Observing Satellite （ALOS） data for Dexing, Jiangxi Province. Then fractal dimension method was used for the whole study area and subregions with different attribute. Results indicate that the whole study area and the subregions with different attribute have self-similarity. The fractal dimension number of mineral area is slightly higher than that of the entire study area. The fractal dimension value of copper mine field is larger than that of gold mine field. The value of ruptured zone with NW, NWW strike is much higher than that with SE strike. It indicates that the larger the value, the more complex the geological structure.
