摘  要：
通过对海拔1 050~1 950 m处土壤样点中有机质、全氮和碱解氮的测定,发现河北省雾灵山地区土壤中有机质、碱解氮和全氮含量垂直变化明显。在1 050~1 200 m处,各项含量均随高度的增加而减少,于1 200 m处达到最低值,在1 200~1 950 m处各项含量又随高度的增加而增加。在同一土壤剖面中,有机质、全氮和碱解氮含量又随着发生层的降低逐渐减少,表层明显高于其他各层。利用回归分析方法将三者的关系一一建立了回归模型,结果表明各回归方程均达到了极显著水平,用该方程描述该地区三者含量之间的关系,具有较高的可信度,模拟效果较好。

摘  要：
By measuring the content of organic matter(OM),total nitrogen(TN) and alkaline nitrogen(AN) in the soil at the height of 1 050 m to 1 950 m in Wuling Mountain,we found that the vertical changes of the content of OM,TN and AN were obvious.At the height of 1 050 m to 1 200 m,the contents of OM,TN and AN decreased with the height increasing.The content of OM,AN and TN was lowest at the height of 1 200 m,but the content of OM,AN and TN increased with the height increasing.In the same soil section,the content of OM,AN and TN gradually decreased with the soil depth,and the content of OM,AN and TN in the surface layer was obviously higher than that in the other layers.The regression model equations among OM,TN and AN were constructed.These equations were very significant and could describe the relationship among OM,TN and AN accurately,with the error less than 0.01 and the good simulation effect.
