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．
