研究了不同林龄马尾松人工林养分特征。结果表明：除了土壤pH值之外，不同林龄土壤理化指标均有显著差异，其中成熟林土壤容重最低为1.16 g/cm3，成熟林土壤含水量、碱解氮和有机质含量最高，分别为167 mg/cm3，20.17％和19.38 g/kg；近熟林土壤速效磷、速效钾、全氮、全磷、全钾含量最高，分别为18.01 mg/cm3，67.86 mg/cm3，1.33 g/kg，0.67 g/kg和28.18 g/kg；不同肥力指标之间存在显著相关关系；根据研究结果计算，不同林龄马尾松人工林土壤肥力由高到低为近熟林"成熟林"中龄林"幼龄林。
研究瞭不同林齡馬尾鬆人工林養分特徵。結果錶明：除瞭土壤pH值之外，不同林齡土壤理化指標均有顯著差異，其中成熟林土壤容重最低為1.16 g/cm3，成熟林土壤含水量、堿解氮和有機質含量最高，分彆為167 mg/cm3，20.17％和19.38 g/kg；近熟林土壤速效燐、速效鉀、全氮、全燐、全鉀含量最高，分彆為18.01 mg/cm3，67.86 mg/cm3，1.33 g/kg，0.67 g/kg和28.18 g/kg；不同肥力指標之間存在顯著相關關繫；根據研究結果計算，不同林齡馬尾鬆人工林土壤肥力由高到低為近熟林"成熟林"中齡林"幼齡林。

The nutrient characteristics were studied in view of different aged Pinus massoniana planta-tions.The results showed that the physicochemical indexes were significantly different at different ages in addition to the pH value of soil.The soil bulk density is the lowest for 1.16 g/cm3 in the mature forest soil,but the water content,available nitrogen and organic matter content of the mature forest soil are the highest,respectively 167 mg/cm3 and 20.17% and 19.38 g/kg;The soil available phosphorus,available potassium,total nitrogen,total phosphorus,total potassium content of near mature forest are the highest,re-spectively 18.01 mg/cm3,67.86 mg/cm3,1.33 g/kg,0.67 g/kg and 28.18 g/kg;There is a significant relationship between different fertility indexes;According to the calculation results,soil fertility of different aged Pinus massoniana plantations is in such an order from high to low as near mature forest>mature for-est>middle age forest>the young forest.
