闽西常绿阔叶林的分类和地理分布研究

TResearch on Classification and Geographical Distribution of Evergreen Broad-leaved Forest in Minxi

常绿阔叶林是我国亚热带温暖湿润地区特有的地带性植被类型。通过全面的实地考察和调查,结果表明:闽西常绿阔叶林植物种类丰富,群落类型多种多样,可划分为2个植被亚型、11个群系组、22个群系、64个群丛,建群种的重要值为45.6～184.0。扼要地阐述了它们的地理分布和生境特点;并根据其现状提出了科学、合理的保护和管理措施。

Evergreen broad-leaved forest （EBLF） is an endemic zonal vegetation in warm and humid subtropics of China. Typical plot investigations show that EBLF in Minxi is varied in community types and may be classified into 2 subvegetation types, 11formation groups, 22 formations and 64 typical associations. The importance value （IV） of constructive species varies from 45.6 to 184.0. The paper briefly discusses their geographical distribution and habitat properties and puts forward scientific, sound conservation and management measures.
