摘　　要：浙江九龙山分布有珍稀濒危落叶树种为主要树种的亚热带常绿落叶阔叶混交林。为探明这些落叶树种在常绿落叶阔叶混交林进展演替过程中生态位变化规律,选择该地区多脉青冈—鹅掌楸林演替过程中4个不同阶段的代表性群落,进展演替过程中,在群落垂直空间上常绿阔叶树不断挤压落叶阔叶树的生存空间,该地区常绿阔叶林顶极群落对珍稀濒危落叶树种是致危生境,不利于生物多样性保护。In the Jiulong shan Mountain of Zhejiang Province, in certain areas were rich in Liriodendron chinense and other rare and endangered deciduous broadleaf trees, form Cyclobalanopsis multinervis—L. chinense forests. To verify these deciduous broadleaf trees niche change law during evergreen broadleaf and deciduous broadleaf mixed community succession, four represent ative communities plots at different succession stages in C. multinervis — L. chinense forests were chos en to investigate, during progressive succession, evergreen broadleaf trees are squeezing L. chinense and other deciduous broadleaf trees living space continuously, It is suggested that, in the area, the evergreen broadleaf climax community is dangerous habitat to L. chinense and other deciduous broadleaf trees, is not in favor of biodiversity conservation.
