摘　　要：以牡丹江市城区现有365块红松次生混交林小班2017年调查数据为研究对象,选取小班树种种类、数量、胸高断面积等数据,通过聚类分析方法,将红松次生混交林划分为四大类型,并通过计算相对多度、相对频度、相对优势度和重要值,分析了不同类型红松次生混交林的树种组成特征。结果表明:红松次生混交林可划分椴树红松阔叶次生混交林、云冷杉红松针阔叶次生混交林、杨桦红松阔叶次生混交林、蒙古栎红松阔叶次生混交林等四大类型。The existing survey data of 365 subcompartments of secondary mixed forest of Pinus koraiensis in Mudanjiang City in 2017 were taken as the research objects,the varieties,quantity and section area of breast height of subcompartments tree species were selected.Through cluster analysis,the secondary mixed forest of Pinus koraiensis was divided into four types.By calculating the relative abundance,relative frequency,relative dominance and importance value,the tree species composition characteristics of different types of secondary mixed forest of Pinus koraiensis were analyzed.The results showed that the Pinus koraiensis secondary mixed forest could be divided into four types,including broad-leaved secondary mixed forest of Tilia and Pinus koraiensis,coniferous and broad-leaved secondary mixed forest of spruce-fir and Pinus koraiensis,broad-leaved secondary mixed forest of poplar-birch and Pinus koraiensis,broad-leaved secondary mixed forest of Quercus mongolica and Pinus koraiensis.
