| 摘 要： | 对京津唐地区浅层地下水240个样本点的氨氮和硝酸盐氮含量进行了测定,应用地统计学方法对数据进行了分析,结果表明地下水中氨氮和硝酸盐氮含量符合对数正态分布。采用简单协克里格方法对未观察点进行了估值,并绘制了氨氮和硝酸盐氮含量空间分布图。将氨氮和硝酸盐氮含量分成8个等级,利用GIS空间分析方法分别统计了各个等级的面积。结果... |

| Abstract: | The nitrogen content of ammonia nitrogen and nitrate of 240 sample points from shallow groundwater of Beijing-Tianjin-Tangshan region are determined.The results of determination are analyzed using Geo-statistics method and the results show that the nitrogen content of ammonia nitrogen and nitrate in groundwater is consistent with log-normal distribution.Simple Co-Kriging method is applied to estimate the value of unobserved points and the spatial distribution of the nitrogen content is plotted.The nitrogen ... |
