摘　　要：以多宝山地区1∶5万水系沉积物资料处理为例,探讨了利用水系沉积物资料进行地球化学分区的R型因子分析方法。该方法通过充分提取样品中所蕴含的地球化学背景信息,进行地球化学分区研究,绘制了能够反映研究区整体地质特征的地球化学分区图,明确了各类子区特定的地质地球化学意义及其相互关联。According to an example of treatment with 1∶50,000 stream sediment data in the Duobaoshan area, R mode factor analysis method which is used to apart geochemical area by stream sediment data is discussed. The method studies the geochemical partition by distilling the geochemical information contained in the samples. Geochemical partition maps reflecting the holistic geological characteristics of the studying area are plotted and the special geochemical meaning of any kind of subregion and the relationship among them are clarified.
