苏州穹窿山植物群落特征及其体感舒适度

文章对苏州穹窿山植物群落的物种重要值、多样性、群落内温湿度和空气颗粒物浓度等进行研究,并评价其体感舒适度。研究结果表明,在紫楠林、栎类林、松林、毛竹林的乔木层中,栎类林和松林的物种丰富度指数(S)最高;栎类林的Simpson多样性指数(D)、Shannon-Wiener多样性指数(H)和Pielou均匀度指数(J)均最高;毛竹林的S、D、H和J均为最低;4类群落的体感舒适度等级均为很舒适,栎类林的体感舒适度最佳;通过相关性分析,植物群落的丰富度指数与其体感舒适度指数呈极显著负相关(体感舒适度指数越高,表明体感舒适度越低),群落丰富度越高,其体感舒适度越好;研究结果可为管理穹窿山森林资源和提升森林的保健功能提供一定理论依据。

Characteristics and Somatosensory Comfort of Plant Communities in Qionglong Mountain,Suzhou City

This paper studies the species importance,diversity,temperature,humidity and air particulate matter concentration of plant communities in Qionglong Mountain,Suzhou City,with the experiments,and evaluates their somatosensory comfort.The results show that,in the forests of Phoebe sheareri,Quercus linn,Phyllostachys heterocycla and Pinus,the Pinus forest and the Q.linn forest boast the highest species richness index(S);the Q.Linn forest has the highest value in Simpson diversity index(D),Shannon-Wiener diversity index(H)and Pielou evenness index(J);and the S,D,H and J of the Ph.heterocycla forest are the lowest.The four plant communities provide people with a good level of somatosensory comfort,while the Quercus Linn forest has the highest level of somatosensory comfort.The correlation analysis shows that the richness index of a plant community is negatively correlated with its somatosensory comfort index.The higher the richness of plant community,the better the somatosensory comfort.This study would provide a theoretical basis for the management of forest resources on the Qionglong Mountain and the enhancement of forest health function.
