Abstract：Soil fertility,tree growth of main stands,and their relationship are studied.The results show that with the succession of progress,tree height,breast high diameter of <i>Pinus korariensis</i>,spruce,fir increased sustainablely,volume of birch and other broad-leaved species decreased;Soil permeability,capillary porosity,non-capillary porosity increased,pH of surface layer(0-10 cm) decreased gradually,organic matter,N,NO3-N,NH4-N increased.For broad-leaved <i>Pinus korariensis</i> forest of different successional stages,the correlation between the average tree height,average breast high diameter and the soil bulk density,soil pH was negative.Capillary porosity and N have little relevance with the average tree height and the average breast high diameter of trees.Using the principal components analysis,we found that the water saturated capacity of soil,capillary porosity,content of organic matter and NO3-N are the mostly factors affecting on the growth of tree and soil fertility at the different growth period.The descending order of soil fertility of different growth periods is: top community,stabilization phase,development stage,and formation stage.The fertility of soil is going on the track of sound progress.
