4) mixed forest
针阔混交林
1.
forest and mixed forest of Picea wilsonii Pinus armandi Betula albo-sinensis, on south-facing slope of the Qinling Mountains were probed into in the paper.
结果表明：针阔混交林林地土壤酸性淋溶过程及物质迁移过程比青林地土壤弱；混交林明显地增加了土壤有机质及N素含量而降低了土壤有效P及有效K的含量；阳离子交换量及水解性总酸度青林地土壤比针阔混交林地高而盐基饱和度比针阔混交林地低，说明了在青林地土壤阳离子交换量中置换性酸所占比例较大而盐基离子所占比例较小；脲酶活性是针阔混交林地比青林地高而磷酸酶活性比青林地低，这与两种林地土壤中水解N及有效P含量高低是一致的。
