Classification of Site Types of Natural Quercus mongolicus Forest in Changbai Mountain Area
摘要
Abstract
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 class Ⅰ plots were mostly shady gradient,middle slope,steep slope and thin soil;Site factors class Ⅱ plots were mostly half shady slope,up slope,slope and thin soil;Site factors class Ⅲ plots were mostly sunny slope or half sunny slope,upper slope,slope and middle soil;Site factors class Ⅳ plots 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 type Ⅲ.关键词
