“关键种”理论与福建南亚热带极度退化生态系统重建构想

The Key Species Theory and the Reconstruction Conception of Extremely Degraded Ecosystem in the Southern Subtropical Zone of Fujian

从“关键种”理论入手 ,结合福建省南亚热带环境与植物资源的实际 ,以实现适宜的顶级群落为目的 ,探讨快速重建福建省南亚热带极度退化生态系统的模式 ,即先使用福建南亚热带当地榕属植物营造生态系统的“关键植物资源”使之能自我维持 ,然后以关键植物资源为构架 ,通过自然扩散和人工协助等综合手段 ,依靠生态系统的自组织 ,重建整个生态系统。同时 ,对运用“关键种”理论指导福建省南亚热带极度退化生态系统重建的几个瓶颈问题 ,以及开展南亚热带极度退化生态系统生态重建实践对“关键种”

Beginning with the Key Species Theory,combined with the fact of southern subtropical zone environment and plant resource in Fujian Province and taking realizing the suitable climax as objective,this paper approached the mode of rapidly constructing the extremely degraded ecosystem in the southern substropical zone of Fujian Province.Meanwhile,some critical problems of using the Key Species Theory to guide the reconstruction of extremely degraded ecosystem in the southern subtropical zone of Fujian Province and the significance of developing ecology reconstruction practice of the aboved ecosystem on the theory itself were approached.
