| 摘 要： | 以河北省张家口龙关地区1∶20万水系沉积物数据为例,采用趋势面分析方法,用不同次数的多项式拟合地球化学元素的整体分布趋势,识别出局部异常,圈定元素异常分布图。在与传统平均方法对比研究后,界定Pb、Zn、Ag、Au、Cu的趋势面法应用效果,为相似区域提供参考。 |

| Abstract: | With 1∶200 000 stream sediment survey data of Longguan area in Hebei Province as an example and by using trend surface analysis,the authors employed different orders of polynomial to fit the overall distribution trend of geochemical elements,recognized local anomalies and drew the anomaly distribution map.Based on a comparison with the traditional average method,this paper evaluated the application results of the trend surface method for Pb,Zn,Ag,Au and Cu,thus providing reference for geochemical work in similar areas. |
| Keywords: | trend surface analysis method traditional average method lead zinc and silver polymetallic ore Longguan area application evaluation |
