| 摘 要： | 作者建立了适合绘制背景图的计算机程序包PPTI,并用之绘制了北京平原地区土壤铜元素背景值的趋势面图和等含量线图.用划分方块作x~2检验的方法检查采样点分布的均匀性,对样点进行了增删.绘出的背景图较好地反映了该元素区域分布的规律,从图中还可以得到元素分布的相关信息.

| Abstract: | A computer plot package (PPTI) for metal background content map plotting was developed and employed to plot the trend charts and isograms for copper background content in soils from Beijing plain region. The uniform distribution of sampling sites was checked by grid dividing and x2 test. The plotted results matched the original data considerably and certain correlative informations can be derived from them. |
