摘　　要：应用分形理论和方法对个旧锡矿遥感信息进行了定量化研究。结果显示，在格子边长为1．4～4．5km的标度范围内，其遥感蚀变和断裂构造进入的总格子数的对数与格子边长的对数均具有很好的线性相关性，表明在研究标度范围内，各子区遥感线性与蚀变信息具有良好的统计自相似性和分形特征。在此基础上，以19号区和26号区为例，分析并进一步探讨了遥感信息分形特征的成矿意义。Based on the theory and methodology of fractal, the authors have quantitatively studied remote sensing information. The results showed apparent linear correlation of logarithm for the grid number into which the remotely sensed alterations and fractures entered to that of side length from 1.4-4.5 km indicating that the statistical self-similarity and fractal characteristics of the remote sensing information are well developed in each subdivision. Based on the results areal9,26 are taken as the examples to discuss the metallogenic significance of fractal characteristics of the remote sensing data.
