福州市住宅小区的绿化植物多样性

Diversity of Landscape Plants in Residential Quarters in Fuzhou

对福州市十个住宅区绿化植物多样性进行调查与分析,结果表明:福州市住宅小区绿化植物群落结构以榕树、香樟和蒲葵为乔木层主体树种,下层以黄槐和朱槿为优势,绿篱和地被灌木以红花继木和假连翘为最多,草本和草坪植物以结缕草、马尼拉草和银边沿阶草最为常见;乔灌草整合物种丰富度指数(Sp)在29~52,乔木层的物种丰富度指数(Sp)、多样性Simp-son指数(D)、Shannon-Wiener指数(H)、均匀度指数(JH)相对较高,灌木层和草本和草坪植物相对较低,其中天元花园、塞纳阳光、锦绣文华和阳光花都的物种丰富度、优势度、多样性、均匀度指数均较高。

The diversity of landscape plants in ten residential quarters in Fuzhou was surveyed and analyzed.The results indicate that the community structure of landscape plants in residential quarters of Fuzhou mainly consists of Ficus microcarpa,Cinnamomum camphora and Livistona chinensis as the main plants of tree layer;Cassia surattensis and Hibiscus rosa-sinensis as the dominant plants in the lower layer;Loropetalum chinense var.rubrum and Duranta repens L.as the prevailing species of hedging and ground cover shrubs;Zoysia japonica,Zoysia matrella Merr.and Ophiopogon intermedius cv.Argenteo as the most common species of herbs and ground cover plants used.The overall species richness(Sp)for herbs,shrubs and trees ranges between 29 to 52,and the Sp Index,Simpson's Index(D),Shannon-Wiener index(H)and the Pielou's evenness(JH)are high in the tree layer but relatively low in the shrub layer and herb layer.Among the ten residential quarters,Tianyuanhuayuan,Sainayangguang,Jinxiuwenhua and Yangguanghuadu are characteristic of a high level of species richness,dominance,diversity and evenness.
