| 摘 要： | 对2005年北京市平谷区农田耕层土壤养分分析结果表明，全区耕层土壤有机质、全氮、速效磷和速效钾的平均含量分别为14．51g／kg，0．89g／kg，32．80mg／kg和136．79mg／kg，有机质和全氮含量总体处于中等水平，速效磷和速效钾含量总体处于高水平。在集中分布区，土壤有机质含量的次数分布曲线近似于呈偏正态分布，全氮近似于呈正态分布，速效磷和速效钾近似于呈偏正态分布。各养分的变异程度由小到大依次为土壤有机质、全氮、速效钾、速效磷。

| Abstract: | The results of the deteriminations of avable soil nutrients in Pinggu District of Beijing showed that the average contents of organic matter,total nitrogen,available phosphorus and available potassium were 14.51 g/kg,0.89 g/kg,32.80 mg/kg and 136.79 mg/kg,respectively.Frequency distribution of soil organic matter appeared in deviated normal distribution,and total nitrogen appeared an approximate normal distribution,and the available phosphorus and available potassium appeared an approximate deviated distribution.The order of coefficient of variation(CV%) was organic matter
