| 摘 要： | 以辽宁省章古台地区不同林龄樟子松人工林为研究对象,通过测定土壤理化性质,对樟子松林地养分状况进行研究。结果表明:1林龄对樟子松林地土壤理化性质影响显著。随着林龄的增加,土壤含水量降低,土壤密度先降低后增加;有机质以及N、P、K质量分数先增加后减少;全Ca质量分数先减少后增加,交换性Ca质量分数逐渐减少。2采用主成分分析法对不同林龄樟子松人工林土壤肥力状况进行了评价,土壤肥力由高到低为:中龄林、近熟林、幼龄林。

| Abstract: | We studied the soil physico-chemical properties in different ages of Pinus sylvestris var.mongolica plantations in Zhanggutai, Liaoning Province.The stand age had significant effect on soil physico-chemical properties.With the increase of stand ages, soil water contents of P.sylvestris plantation decreased, whereas, the soil bulk density firstly decreased and then increased.The soil organic matter, N, P, and K contents firstly increased and then decreased.Total Ca content firstly decreased and then increased, and exchangeable Ca content decreased.The soil fertility of Pinus sylvestris var.mongolica plantation was assessed by principal component analysis, and the soil fertility from high to low was middle-age forest, young forest and nearly mature forest. |
