楠竹(Phyllostachys pubescens)的地下茎具有强大的无性繁殖能力,当楠竹蔓延至针叶林、阔叶林或针阔混交林时,即形成竹针、竹阔和竹针阔混交林。过去,本县竹林绝大部分是混交林,天然的混交林是竹针阔混交林,即楠竹与马尾松(Pinus massoniana)、枫香(Liquidambar formosana)、木荷(Schima superba)及槠栲类(Castanopsis spp.)常绿阔叶树的混交。半天然混交林是竹针混交林,
The underground stem of Phyllostachys pubescens has a strong ability of asexual reproduction. When bamboo spreads to coniferous forest, broad-leaved forest or mixed coniferous and broad-leaved forest, it forms bamboo-needle, bamboo-broad and bamboo-coniferous and broad-leaved mixed forest. In the past, most of the bamboo forests in this county were mixed forests. The natural mixed forests were mixed bamboo-coniferous and broad-leaved forests, namely Pinus massoniana, Liquidambar formosana, Schima superba, Castanopsis spp. Evergreen broad-leaved tree mixed. Semi-natural mixed forest is bamboo mixed forest,
