茂兰自然保护区旅游景点植物群落结构及多样性

为进一步开发茂兰自然保护区的旅游资源,更好地保护植物多样性提供参考依据,调查了茂兰自然保护区石上森林、水中林和九洞天3个旅游景点的植被种类,计算分析丰富度指数、均匀度指数、Simpson指数和Shannon-wiener指数。结果表明:景区植物共74科152属257种,其中,乔木有32科52属71种,灌木50科94属148种,草本有27科37属53种,蕨类有7科12属20种;乔木层、灌木层和草本层都没有明显的优势种,群落以落叶树种、纸质叶和高位芽植物为主,群落的丰富度指数、均匀度指数和多样性指数较高,结构复杂稳定。

Community Structure and Plant Diversity of Tourist Attractions in Maolan Nature Reservation

In order to further develop the tourism resources in Maolan Nature Reservation and to preferably protect plant diversity,the author investigated vegetation types of three tourist attractions in Maolan Nature Reservation,and analyzed the calculated richness index,evenness index,Simpson index and Shannon-wiener index.The results showed that there were a total of 257 ornamental plant species belonging to 152 genera and 74 families.Including 71 arbor species of 52 genera of 32 families,148 shrub species of 94 genera of 50 families,53 herbaceous plant species of 37 genera of 27 families,20 fern species of 12 genera of 7 families.Tree layer,shrub layer and herb layer had no obvious dominant species.Deciduous trees,paper leaves and shoots of plants in high-dominated communities,and richness index,evenness and diversity indices of community were high.So the community structure was complex and stable.
