贵阳市红枫湖库区植被群落结构特征分析
|
摘要
为了解红枫湖库区植被群落的现状,进行样地调查,分析植物群落结构。结果表明,调查区域内共有植物170种,隶属于78科146属;根据乔木层重要值计算及结合群落优势种组成,将区域内植被划分为亮叶桦林、马尾松林、翅荚香槐林、暖温性针叶林、落叶阔叶林、针阔混交林和常绿落叶阔叶混交林7种主要类型;径级结构方面,各群落小径级林木(2.50～7.49 cm)占据优势;通过Gleason多样性指数的计算,落叶阔叶混交林的多样性指数是最高的,针阔混交林其次,常绿落叶阔叶混交林最低;油茶是灌木层中的绝对优势种,应作为人工干预采伐的林木,促进其他树种的更新。该研究可为该地今后开展植物多样性保护和生态公益林建造提供理论依据。
To understand the status of vegetation community in Hongfeng Lake reservoir area,using sample survey site method to analyze plant community structure,the results showed that there were 170 species of plants belonging to 146 genera of 78 families in the survey area. According to the calculation of the important value of tree layer and the composition of dominant species in the combined community,the vegetation in the region was divided into 7 main types: Betula luminifera forest, Pinus massoniana forest, Cladrastis platycarpa forest, warm-temperate coniferous forest, deciduous broad-leaved mixed forest, coniferous broad-leaved mixed forest and evergreen deciduous broad-leaved mixed forest. In diameter class structure, small path class forest occupied the superiority in each community. By Gleason's diversity index calculated,the diversity index of deciduous broad-leaved mixed forest was the highest, followed by coniferous mixed forest and mixed evergreen deciduous broadleaf forest was lowest. Camellia oleifera was the dominant species in shrub layer,should serve as the tree that manual intervention cuts,promote the regeneration of other tree species.This study can provide theoretical basis for plant diversity protection and ecological public welfare forest construction in the future in this area.
