神农架重点保护植物及其园林应用

Key-Protected Plants and Its Garden Application in Shennongjia

摘要:

摘要：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1 000～1 500 m间种类最多，峰值在1 200 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。

Abstract: In order to understanding the features of key protected plants, we processed the protected plant lists statistically and then analyzed their distribution, habitat, growth states, ornamental features and garden application. There were 139 species of key protected plants, included 76 species of Orchidaceae. There were 38 tree species occupying 808% of wood plants. The most diversity appeared in elevation of 1 000～1 500 m and its top appeared in 1 200 m. Enjoying flowers type, which occupied 56.0%, was the most. Results showed that 72.4% species grew well in local plant ex situ conservation case. Introduction from high attitude to low attitude was easier than from low to high. Shade plants and half shade plants occupied the main and a lots was suitable to the sun environment, which reflected the vegetation characteristics of north subtropical monsoon climate.
