Abstract: The study shows: 1.The amount of bacteria is the highest and counted for more than 95% of the total microbes in grey-cinnamon soil of Picea schrenkiana var. tianshanican forests. 2.The soil microbes are mainly concentrated in upper layer(A₀,A₁). Their amount decreases rapidly with increasing soil depth. 3.The amount of the microorganism of physiological group sequence ranging from high to low is:ammonifiers>genus bacillus>cellulose decomposing bacteria>nitrobacteria>azotobacteria. 4.The enzyme activity in the upper layer of the soil is more active than in the bottom layer. 5. The total number of soil microbes, the number of various microbial physiological groups, the ecological distribution of microfungi dominant genus and the soil enzymes activity vary with different forest types and soil types. The forest soil fertility has a correlation with the total number of soil microbes and the numbers of various microbial physiological groups and the soil enzymes activity. The level of the forest soil fertility in leached grey-cinnamon soil is higher than in ordinary grey cinnamon soil.
