摘　　要：基于2014年吉林省第八次森林资源连续清查数据,调查490块天然蒙古栎林样地。采用主成分分析和聚类分析方法对长白山区天然蒙古栎林立地类型进行划分。主成分分析结果表明:立地因子对立地类型划分的影响顺序为坡向>坡位>坡度>土层厚度>海拔>腐殖质厚度。当聚类系数为0.6683时,可将490块天然蒙古栎林样地划分为4类:Ⅰ类立地因子多为阴坡、中坡、陡坡、薄土;Ⅱ类立地因子多为半阴坡、上坡、斜坡、薄土;Ⅲ类立地因子多为阳坡或半阳坡、上坡、斜坡、中土;Ⅳ类立地因子多为阳坡、上坡、平缓坡、中土,最适合天然蒙古栎林生长的是Ⅲ类立地类型。Based on the data of the eighth continuous inventory of forest resources in Jilin Province in 2014,490 natural Quercus mongolicus forest plots were investigated.The site types of natural Quercus mongolicus forest in Changbai Mountain area were divided by principal component analysis and cluster analysis.The results of principal component analysis showed that the order of influence of site factors on land types was slope direction>slope location>slope gradient>soil thickness>elevation>humus thickness.When the cluster coefficient is 0.6683,490 plots of natural Quercus mongolicus forest in the study area could be divided into four types:site factors classⅠplots were mostly shady gradient,middle slope,steep slope and thin soil;Site factors classⅡplots were mostly half shady slope,up slope,slope and thin soil;Site factors classⅢplots were mostly sunny slope or half sunny slope,upper slope,slope and middle soil;Site factors classⅣplots were mostly sunny slope,upper slope,gentle slope and middle soil.The most suitable site conditions for the growth of natural Quercus mongolicus forest was site typeⅢ.
