不同类型居住区植物种类与配置的差异分析——以徐州市居住区为例

Analysis on the Difference of Plant Species and Disposition in Different Residential Areas——A case analysis of the residential areas in Xuzhou City

采用样方法调查研究徐州市城区内三类居住区绿地植物群落的基本情况和物种多样性,结果表明,样地内共分布植物154种,隶属于61科116属,重要值的计算结果显示其中香樟(Cinnamomum camphora)、石楠(Photinia serrulata)、狗牙根(Cynodon dactylon)具明显优势,方差分析发现不同类型居住区间物种丰富度具显著差异。就乔灌层而言,物种不丰富,但分布均匀,多度没有集中于少数几个种;在Gleason丰富度指数、Simpson指数、Shannon-Weiner指数和Pielou均匀度指数方面均为别墅区>传统居住区>安置区。在此基础上,从植物选择及配置角度,分析不同类型居住区存在的问题并提出解决办法,旨在为未来不同类型居住区园林绿化的建设提供经验和借鉴。

In urban district of Xuzhou, a sample method was used to investigate the basic situation and species diversity ofgreen plant communities in three types of residential areas. The results showed the total plants belong to 61 families, 116genera and 154 species in all sample plots. The important value of the calculation results showed that Cinnamomumcamphora, Photinia serrulata and Cynodon dactylon had obvious advantages compared with others. Variance analysisshowed that species richness of different types of residential areas was significantly different. As far as arbor and shrub layeris concerned, species are not rich but evenly distributed, abundance is not focused on few species. The results presented asthe followings： villa residential area〉traditional residential area〉resettlement residential area according to the values ofGleason richness index, Simpson index, Shannon-wiener index and Pielou evenness index. On this basis, from the point ofview of plant selection and configuration, this paper analyzes the problems existing in different types of residential areas andputs forward solutions to provide experience and reference for the construction of landscaping in different types of residentialareas in the future.
