摘要:
以冀北山地华北落叶松人工林与油松天然次生林为研究对象，对不同坡位气象因子、立地因子等方面的差异进行研究。结果表明：华北落叶松人工林内测定点温湿度均高于油松林，同一林分内温度差异不显著。落叶松林内照度随着海拔增加逐渐增大，油松群落内坡底照度最高。油松、落叶松群落随着海拔的增加，各样地相同土层间土壤质量含水量、饱和含水量、相对含水量逐渐减小，相同海拔落叶松林样地各土层水分指标均高于油松林。油松各样地内土壤容重随着土层深度的增加而增加，且随着海拔的增高，各样地相同土壤层次容重值增大。落叶松林变化均不显著。油松各样地土壤孔隙随着土层深度和海拔的增加均变小。落叶松林变化均不显著,但在相同土层上落叶松林土壤孔隙多于油松林。油松林地土壤颗粒随着土层深度的增加而减小，落叶松林则增大。油松及落叶松群落坡中样地土壤颗粒均较大。2个林分土壤pH随着土壤层次的增加而增加，土壤养分含量随土层深度增加而递减；随着海拔增高，相同海拔落叶松林内有机质、全氮、全磷、碱解氮、有效钾含量均高于油松林，而速效磷则相反。
