乌鲁木齐市居住区木本植物物种多样性调查研究

Investigation and Study on Species Diversity of Woody Plants in Residential Areas of Urumqi

居住区绿地是城市园林绿地系统的组成部分,研究居住区植物多样性可为城市生物多样性保护提供基础数据。采用典型抽样法,对乌鲁木齐市具代表性的居住区的木本植物物种多样性进行了分析研究。结果表明:4个居住区共有26科47属88种木本植物。从居住区绿地的乔、灌层分析比较得出,居住区乔木层物种组成结构复杂;灌木层物种多样性指数、均匀度指数相对较低,物种多样性仍有较大的提升空间;从居住区的4种绿地类型来看,公共绿地的物种多样性水平较高,道路绿地的物种多样性水平最低;在居住区树种的选择上,野生观赏植物资源的应用未得到重视。

Green space of residential areas plays a key role in urban ecosystem.The study on plant diversity in residential areas can provide basic data for city biodiversity conservation.In this paper,typical sampling method was used in species diversity study of woody plants in representative residential areas of Urumqi.The results showed that：in the survey of the residential areas,there were 88 species of woody plants belonging to 47 genera in 26 families.Derived from the analysis of the tree and shrub layers of the green space of residential areas,the species composition of tree layer was complex;species diversity and uniformity of shrub layer were relatively low,and there was still much development space in species diversity of shrub layer.From the four kinds of green space type of residential areas,there was the highest species diversity in public green space and the lowest one in roadside green space.Application of wild ornamental plant resources was overlooked in residential areas,and the level of species diversity in residential areas was related to the construction time.
