摘　　要：探讨地球化学元素含量异常方法。根据地球化学元素含量具有非正态分布和后尾性分布的特性,利用GPD设计了地球化学异常提取模型,并对相关参数进行了讨论。将设计的模型应用于实际数据处理中,结果发现该方法能够有效提取地球化学元素异常,提取的地球化学元素异常分布与矿体吻合,表明设计的模型具有合理性。In order to study the extraction method of geochemical element content anomaly.combination the non-positive distribution and tail characteristics of geochemical element content,a new geochemical anomaly extraction model is designed by using GPD,the relevant parameters of GPD are also discussed.Lastly,the designed model is used to process the actual data,it is found that the method can effectively extract the anomaly of element,and the distribution of geochemical element anomaly region is consistent with the ore body,which indicating that the designed model is reasonable.
