基于数据库的地球化学异常特征参数计算方法
|
摘要
介绍了在地球化学普查中,一种单元素异常特征参数的计算方法。在确定了单元素异常下限,建立了取样点位数据图层,完成了单元素异常图制作的基础上,将单元素异常区图层与点位数据图层做点对区的相交分析,把单元素异常区中异常编号、异常面积字段的空间信息相交分析到异常区内点位数据图层中,将该点图层属性转换成DBF文件,应用FORXPRO软件编写了程序,从而计算单元素异常特征参数。
This paper introduces a kind of calculation method for characteristic parameters of single element anomaly in the geochemical reconnaissance. After the determination of lower limit of single element anomaly,the data layer of sampling point position is established,the single element anomaly map is prepared,area-to-point spatial analysis is conducted between the area layer of single element anomaly and the data layer of point position,and the spatial information on anomaly number,anomaly area and perimeter field in the area of single element anomaly is superimposed on the data layer of point position. The application software is programmed to calculate the characteristic parameter of single element anomaly.
