摘  要：
[目的]探索松材线虫病入侵30余年紫金山马尾松林植物群落结构特征及演替进程。[方法]对松材线虫病危害前为马尾松林,现为阔叶林、针阔混交林、马尾松林的植物群落结构、Margalef物种丰富度(S1)、个体数量、Shannon-wiener多样性指数(H')、Pielou均匀度指数(J)、Simpson生态优势度(C)及重要值进行了调查、分析和比较。[结果]紫金山原马尾松林植被群落正处在被地带性混交森林植被群落逐渐替代的不同演替阶段;3种植被群落乔木层主要树种相互间具有相关性,这种相关性与马尾松重要值的消涨密切关联,马尾松重要值的消涨除受到松材线虫病的影响外,还受到植树造林、直播造林、卫生伐、森林抚育等人为因素的影响;3种植被群落灌木层均未见马尾松,灌木层主要树种的相对密度消涨除了人为因素的影响外,树种的生态适应性和生理生态功能的差异是其中重要的原因;3种植被群落草本层以阔叶林中物种最为丰富,马尾松林草本层种类多于针阔混交林,草本层植物种类分布对环境有极大的依赖性;现在的马尾松林、针阔混交林、阔叶林乔、灌层中的植物种类、S1和H'均呈递增趋势,与C的变化趋势相反,H'和J的变化趋势不一致,原马尾松林整体朝着马尾松阔叶混交林、落叶阔叶混交林、常绿落叶阔叶混交林方向进行演替。[结论]该研究可为紫金山森林培育提供指导。

摘  要：
[Objective]To explored the structural characteristics and the process of succession of the Pinus massoniana community that invaded by Bursaphelenchus xylophilus more than 30 years in Zijin Mountain.[Method]The plant community structure,Margalef species richness(S1),individual quantity,Shannon-wiener diversity index(H'),Pielou evenness index(J),Simpson ecological dominance(C) and important value were investigated,analyzed and compared which the pine wood nematode disease was the Pinus massoniana forest,and now it was broad-leaved forest,coniferous and broad-leaved mixed forest and Pinus massoniana forest.[Result]The results showed that tree species of the three vegetation communities tree layer had correlation.This correlation was closely associated with the rise and fall of Pinus massoniana,besides the influence of Bursaphelenchus xylophilus,and tree planting,forestation,sanitation felling,forest tending such as human factors.The shrub layer were not seen Pinus massoniana among these three vegetation communities.The important reasoned that the rise and fall of shrub layer main tree species were its ecological adaptability and the difference between physiological and ecological functions.The richest species of herb layer was in the broad-leaved forest and then was the herb layer in Pinus massoniana forest.The distribution of plant species of herb layer had great dependence on the environment.The plant species,S1,H' among the shrub layer of the three forests all showed trend of increasing,and the change trend of C on the contrary,change trend of H',J were discordant.The original Pinus massoniana forest was in succession that overall toward the Pinus massoniana broad-leaved mixed forest,deciduous broad-leaved mixed forest,evergreen and deciduous broad-leaved mixed forest direction.[Conclusion]This study can provide guidance for the forest cultivation in Zijin Mountain.
