Abstract: On the basis of investigation in the forest of Larix gmelinii in Mohe forest area, we realized that the distribution of the forest types is selected correctly. The sample plots are ordinated by means of principal component analysis (PCA). According to Fisher test analysis, the classification were recognized as justified. The research result shows that distribution of forest types is influenced by the situation of slope which is the most important factor. Secondly, aspest, gradient, soil moisture and depth of soil layer are also important factors. The interaction between topographic factor and soil condition affects the distribution pattern of forest types.
