  1. In the paper, the main results are brought forth in five aspects as follows : ( 1 ). the analysis of statistics the characteristic indicated that the variation coefficient of the soil nitrogen density of 0 ~ 30cm depth is lower, the variation coefficient is only 3. 6 %, the variation coefficient of the nitrogen density of 0 ~ 100cm depth is much bigger than that the 0 ~ 30cm depth, it is 100 %. based on the second national soil general survey material, the average soil profile depth is 101cm, this is in corresponding with skew normal distribution, its standard deviation is 0. 0192

    通過研究,得到以下認識與結果: ( 1 )統計特徵分析表明, 0 30cm厚度土壤氮密度的變異系數較低,為3 . 6 , 0 100cm厚度的氮密度的變異系數相對于來說就很大,為100 ;全國土壤剖面深度平均為101cm ,符合偏正態分佈,標準方差為0 . 0192 ; 0 30cm厚度土壤氮密度服從對數正態分佈,而0 100cm厚度土壤氮密度基本服從偏正態分佈。
