Abstract: On the basis of investigation of sample plots, statistical analysis demonstrate the relationship between site factors and natural Larix gemlini growth.The dominant factors are found by three multiple statistical analysis (quantizedmodel-1, general variance analysis and principal component analysis). Theorder according to their importance is: copographical position, soil layer depth, slope aspect, slope gradient and soil moisture. Site type groups and sitetypes are divided according to the dominant factors. This investigation mayprovide the bases for predicting forest land productive forces and working outreasonable afforestation plan.

Key words: Forest site, Natural Larix gemlini forest, Site type, Multiple statistical analysis
