- 摘要:
- 生物多样性的维持是城市公园的一项重要生态功能，在城市环境建设和城市绿地生态效益发挥中具有重要的价值。通过对西安市21个公园40个样方的调查，发现西安城市公园共有57种树木，分属31科46属，本土树种占46.2%，国内引进种占总数的27.2%，国外引进种占总数的26.6%。所调查的21个公园物种丰富度Margalef指数为1.87，多样性指数Simpson指数为0.76，Shannon-Wiener指数为1.66，Pielou均匀度指数为0.80，表现出中等水平的多样性。西安城市公园以引进种占优势的这种树木组成，新建公园的较大树径，主要是人工配置的结果。说明社会经济的发展对城市公园的生物多样性有着重要的影响。
- Abstract:
- The species biodiversity maintaining is an important ecological function of urban parks, which has great value in an urban landscape and ecological benefits of urban green space. The 40 plots with 20 m×20 m in 21 parks in Xi’an City were investigated. Among these urban parks, there are 57 species trees belonging to 31 families and 46 genera. The native species accounted for 46.2% of total species, the alien species from domestic and foreign introduction accounted 27.2% and 26.6% of total species. For species biodiversity index of trees in 21 investigated urban parks in Xi’an City, the Margalef species richness index was 1.87, the Simpson index was 0.76, Shannon-Wiener index was 1.66, Pielou uniformity index was 0.80. Compared with other cities, the results showed the moderate levels of tree diversity in Xi’an urban parks. The alien species were dominant in the tree species composition, the trees with larger diameter in newly constructed parks in Xi’an City resulted from artificial configuration. Thus, socio-economic development has the important influence on biodiversity in the city park.
