摘要
为研究对比传统统计法和趋势面法数据处理前后的变化特征、异常区圈定的分布特征,以大华山1∶5 000水系沉积物数据为例,选取具代表性的Au和As为研究对象,得出两种方法优劣,圈出局部异常,确定重点勘查区域。结果显示趋势面法有效弥补了传统平均法采用同一异常下限值圈定异常区的不足及异常下限系数的不稳定性。
To compared variation characteristics of the data before/after treatment and distribution characteristics of abnormal delineation of traditional statistical methods, cumulative frequency france and trend-surface method. In this paper, taking DaHua- shan 1：5000 stream sediment data as an example, selected the representative Au and As as the research object, obtained the advantages and disadvantages of＂ the three methods, circle the local anomalies, identified the key exploration area.
