摘要: 本文根据在管涔山北部海拔1800—2600m阴坡半阴坡6,5寒温性针叶林内调查的37块标准地材料,对寒温性常绿针叶林(云杉林)生产力和土壤理化因子及地貌条件进行了单相关分析和多元逐步回归分析。结果表明:土壤的机械组成,pH值和CaCo3含量是主要影响因子;接近中性,没有石块,并且有上粗下粘结构的土壤,有利于寒温性常绿针叶林生长,还说明了土壤持水能力对云杉林的影响。通过分析和逐步筛选主要影响因子,建立了预报云杉林生产力的方程。

Abstract: In this paper,correlation and regression analysis arc used to deal with the correlations between produetion of Spruce and soil charaeteristicS and geomorphology according to findings of 37 plots in the forest which distribute 0n the north side and seminorth Side of hill with all altitute of 1800-2600m above sea-level in north Guanqin mountain.The result indicates that the main factors are texture,pH and CaCO3 content of soil~the favour able conditions are the lower pH,no stone and the sandy soil Structure on upper layer and clayey soil on.lower layer.The latter indicates indirectely that the water-holding capacity of soil has effects upon growth for spruce.In order to predict the productivity of spruce,an equation in re spect to the main influence factors is set up.Following analysis of characteristics of the main factors,the paper explains the special characteristics of.burozem in its physical and Chemical nature.Interhal relations between the main factors and the conifers.In this area,and the habitat suitable its growth.
