采用试验分析与地统计学方法对陕西省澄城县91个样区小麦土壤全氮含量进行了空间结构分析.结果表明:样点原始全氮值不符合正态分布,经Cox-box变换后符合正态分布;普通克里格插值法半变异函数符合圆型模型,函数块金值为3.79×10-3,偏基台值为4.15×10-3,变程为4856 m;澄城县调查样区96.7%的小麦地土壤全氮含量处于不同的缺乏状态.

To explore the distribution of soil total nitrogen in the spatial of Chengcheng County and to devise reasonable fertilization scheme,the author investigated total nitrogen structure of wheat soil in space for 9 1 sample region chose in Chengcheng County of Shanxi Province,with applying the experimental anal-ysis and statistical methods.The results showed that the distribution to original total nitrogen value was not the normal distribution in the sample area,but it was norma by Cox-box transform;Half variant func-tion was fit for the circular model,the Nugget was 3.79×10-3,the Partial Sill was 4.15×10-3,and the range was 4 856 m;96.7% wheat soil among the county-wide surveyed sample region were of lack in total nitrogen content.
