Present resource situation and suggestion for conservation of Heptacodium miconioides in Zhejiang Province, East China(浙江省七子花资源现状及保护建议)
七子花是我国特有的单种属珍稀濒危植物,为国家二级重点保护野生植物,主要分布于浙江、安徽和湖北,而浙江是其分布中心.作者在野外调查的基础上,分析了浙江省七子花的地理分布特点、种群数量和群落类型.结果显示:浙江有七子花分布的群落总面积为54.28公顷,保存有七子花约近3万株(丛),并集中分布在临安等5个县市.七子花分布的群落类型较多,但未见于常绿阔叶林中,反映了七子花是在人类长期干扰下勉强生存.但是,七子花对非生物环境的适应幅度较宽,其种群的生存和发展还是有希望的.最后,根据七子花的资源现状,提出了加强保护和持续利用的建议....
