摘　　要：本文在简要介绍分形技术及分形模型的基础上,应用分形模型研究了化探数据的元素含量与对应面积,发现数据存在分形结构,并确定了化探数据的异常下限,经和传统方法处理后所得到的结果进行比较,发现分形处理结果较传统方法的效果更好。The fractal method of data processing and fractal models are briefly introduced and applied to study the relationship between elemental contents of the stream sediments and their corresponding distribution areas in this paper. It is discovered that there is fractal dimension character in geochamical data. Then the low content limits of elemental anomalies were set up for reprocessing the geochemical survey data. It is believed that the anomaly image obtained through the application of fractal method of data processing is better than that obtained through the application of traditional data processing method.
