中文摘要：

采用典型取样法,沿海拔梯度对安徽清凉峰国家自然保护区植被进行调查,调查区域内主要以常绿阔叶林和常绿-落叶阔叶混交林两种森林植被类型为主。菊科和蔷薇科是物种数目最大的两个科。各层次植物物种平均丰富度大小依次为草本层〉灌木层〉乔木层,Simpson多样性指数为灌木层〉乔木层〉草本层,平均Shannon-Wiener多样性指数呈现出乔木层〉草本层〉灌木层的特征。乔木层、灌木层、草本层植物多样性最高值分别出现在海拔约1300、1100和800m左右的区域。此外调查过程中还发现多种野外珍稀濒危植物,并提出了对濒危植物的保护建议,此研究为安徽清凉峰国家级自然保护区植物资源的可持续发展提供参考。

英文摘要：

Samplings were gathered and examined in Anhui Qingliangfeng Mountains,along topographical gradients.The major communities can be classified as evergreen broad-leaved forest and evergreen,deciduous broad-leaved mixed forest community.The average species richness in different layers follows the order：herb layer〉shrub layer〉tree layer.The average Shannon-Wiener diversity index were showed as tree layer 〉herb layer〉shrub layer.The average Simpson diversity index were showed as shrub layer〉tree layer 〉herb layer.The highest diversity of tree layer appeared in the area with an elevation about 1300 m,whereas shrub layer appears about at 1100 m,and herb layer appears about at 800 m.In addition,this paper introduces the rare and endangered wild plants which were found during the research.Some suggestions about how to protect them are put forward.These results will benefit for the development and plant resource utilization of Anhui Qingliangfeng Mountains.
