摘要:通过对湖南株洲市大京水库集水区马尾松群落组成成分、形成历史、发展趋势、物种多样性等调查分析,结果表明,水库集水区马尾松群落演替有3大特点:①马尾松林附近保存有小面积常绿阔叶林和零星常绿阔叶树,马尾松林演替有充足的种源,而且演替速度较快;②其演替规律为由马尾松纯林演替为马尾松、常绿阔叶树混交林,再演替到常绿阔叶林,一般不经过马尾松、落叶阔叶树混交林阶段;③首先侵入林地的常绿树为茹豆、石栎、黄瑞木、青冈栎等。物种多样性分析表明马尾松纯林的丰富度、均匀度和多样性指数均低于马尾松与阔叶树混交林;在立地条件较好、树种组成较丰富的马尾松与常绿阔叶树混交林的物种多样性指数接近甚至高于常绿阔叶林。
Through the investigation and analysis of composing component,formation history,developing tendency,species diversity of Pinus massoniana in Dajin Reservoir watershed area,Zhuzhou,Hu'nan,Pinus massoniana community succession had 3 characters: ① a small area of evergreen broad forest and some evergreen broad forest existed near Pinus massoniana forest.There was sufficient species provenance for Pinus massoniana succession,the succession speed was fast;② The succession law was the successions from Pinus massoniana pure forest to Pinus massoniana and evergreen boradleaved mixed forest,and from pure forest to evergreen broadleaved mixed forest without mixed forest period;③Elaeocarpus japonicus,Lithocarpus glaber,Adinandra millettii,Cyclobalanopsis glauca intruded into forestland,the pure forest rich,and average degrees,and diversity indexes were lower than the mixed forest;the species diversity index of mixed forest with good site condition and rich species compositon was close to and higher than evergreen broadleaved forest.
