Abstract: Determinant factors influencing growth of Larix olgensis were screenced and interrelationships among topography soil and growth of L. olgensis were studied employing pathway analysis (PA), principal component analysis(PCA) and canonical analysis(CA). The research indicates that determinant factors are exposure soil texture, soil depth, and exposure is closely related to organic matter, soil texture, soil depth. Site classification was made by using a method of ecological forest site classification. 3 groups of site type and 14 main site types were devided for L. olgensis in the East part of Liaoning. Group of site type on shaded slope included 5 site types: thick, moderate silt loam and thick, moderate loam and thick clay loam. Group of site type on half-shaded and half-sunny slope included 6 site types: thick, moderate silt loam and thick, moderate loam and moderate sandy loam soil and thin soil. Group of site type on sunny slope included 3 site types: thick, moderate and thin soil.

Key words: Forest site, Classification, Larix olgensis, Liaoning Province
