在对即墨市绿地系统内各绿地类型调查的基础上,对其木本植物多样性现状进行了研究。结果表明:在所调查的样方内共有木本植物95种(品种),隶属于33科68属。其中,应用频度较高的是樱花(Cerasus serrulata)、大叶黄杨(Euonymus japonicus)、龙柏(Sabina chinensis‘Kaizuca’)。5种绿地类型中,Margalef丰富度指数和Shannon-Wiener多样性指数:综合公园>居住绿地>道路绿地>公共设施绿地>工业绿地;Pielou均匀度指数:工业绿地>公共设施绿地>道路绿地>居住绿地>综合公园。通过与其他城市分析比较可以看出,即墨市城市绿地木本植物多样性总体偏低,灌木尤低。在今后的城市绿地建设中应首先丰富灌木种类。
Based on the investigation of the types of green land in Jimo green space system, the current status of woody plant diversity was studied. The results showed that 95 species (varieties) of woody plants were found in the sampled plots, belonging to 33 families and 68 genera. Among them, Cerasus serrulata, Euonymus japonicus and Sabina chinensis ’Kaizuca’ were the most frequently used ones. Margalef richness index and Shannon-Wiener diversity index of five kinds of greenbelt types: general parks> residential greenbelt> road greenbelt> public facilities greenbelt> industrial greenbelt; Pielou evenness index: industrial greenbelt> public facilities greenbelt> greenbelt> residential Greenland> General Park. Through the analysis and comparison with other cities, we can see that the diversity of woody plants in Jimo urban green land is generally low and the shrubs are extremely low. In the future construction of urban green space should first enrich the shrub species.
