| 摘 要： | 在地球化学勘查项目的资料整理中,应用C#2.0语言编制应用程序,实现批量统计圈定地球化学异常的特征参数及综合异常参数和评序,方法简便,省时、准确。首先建立包含样点坐标和元素分析数据的文本格式文件,将MapGIS软件制作的地球化学异常图及综合异常图的异常边界线转换成"SDTF格式",利用程序读取各元素异常区内的数据,统计其异常面积、平均值、衬度、规模等异常特征参数。再根据程序计算后的综合异常面积、平均衬度、规格化面金属量三个指标对其进行评序,输出统计结果值表,该方法为进一步研究地球化学异常特征提供了数据支持。

| Abstract: | During the data processing in geochemical exploration,The realization of characteristic parameter statistics and comprehensive anomaly ranking in geochemical anomaly by using C#2.0 language is convenient,time-saving and accurate.First,after setup that a file in text format containing sample coordinate and elements analysis data and changing the format of abnormal boundary line in geochemical anomaly map and comprehensive anomaly map made by MapGIS program into "SDTF" format,we let the program to read the data in every elements anomaly area and gather statistics about its anomaly area,average,contrast,dimension.Then we make the ranking by using the following three indexes: comprehensive anomaly area,average contract after the calculation of program,export statistical results table,which provided important data support to the further study of geochemical abnormal characteristics. |
