神农架重点保护植物及其园林应用

Key-Protected Plants and Its Garden Application in Shennongjia

为弄清神农架重点保护植物基本状况及栽植应用特点,对保护植物名录进行综合统计,分析保护植物的分布、生长环境和当地栽培生长情况,对观赏应用类型进行描述.重点保护植物有139种,其中兰科植物76种.乔木有38种,占木本类的80．8％.在海拔1000～1500 m 间种类最多,峰值在1200 m.观赏类型以观花类为主,占56．0％.当地迁地栽培的结果是,72．4％的重点保护植物生长较好.高海拔植物引种到低海拔较易,而低海拔引种到高海拔较难.阴生和半阴生植物居多数,也有不少植物能适应于阳生环境,反映神农架北亚热带季风气候的植被特征.
