【摘要】 本文对传统统计方法、85%累频、概率格纸法等常规统计方法和非线性统计分析方法—分形含量面积法对谢通门地区水系沉积物中的Au元素数据进行对比分析,发现传统统计方法和85%累频法不能很准确的将靶区圈定出来,而其他两种方法能将靶区很好的凸显出来。但概率格纸法在圈定异常时会漏掉一些弱异常,非线性统计方法分形含量面积法将概率格纸法漏掉的弱异常圈定出来。与常规方法相比,非线性统计方法分形含量面积法所取得的效果更好。更多还原

【Abstract】 The auther made statisc calculation of stream sedment data on Au using general statistical analysis methods,such as, Traditional statistical methods、cumulative percen tage of 85% and probability grid paper method, and nonlinear statistical analysis methods – fractal in Xietongmen area. Traditional statistical methods and cumulative percen tage of 85% can not find the prospecting target accurately, but other methods can find the prospecting target accurately. The probability grid paper method may ignore some weak anomaly area, but the fractal can find it. Compared with the conventional method, nonlinear statistical methods of fractal method can do better.更多还原
