The largest total P content in the different layers is larix principis-rupprechtii community,the smallest is broadleaved mixed forest of poplar-birch-oak. The average content of soil available phosphorus is 19.8mg/kg, for most species it can satisfy the need.
土壤碱解N含量最大的为华北落叶松群落；华北落叶松群落全P含量在不同的土层中均表现为最大,全P含量最小的均为杨树、桦树、栎树阔叶混交林,研究地土壤速效磷平均含量为19.8mg/kg,对于大多数树种来说已能满足需要；研究地土壤全K平均含量为2.83%,属于含K量较丰富的地区。
