- 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.
