摘　　要：[目的]探究城市化强度与木本植物多样性之间的空间关系。[方法]以青岛市主城区的城市森林为研究对象,在样地调查的基础上,运用SPSS软件分析了城市化强度与木本植物多样性指数之间的相关性,同时利用地理加权回归模型建立了二者之间的空间关系。[结果]青岛市主城区木本植物多样性具有明显的空间异质性;城市化强度与木本植物丰富度指数之间具有显著相关性,与香浓维纳指数和均匀度指数之间显著不相关;地理加权回归分析结果表明,城市化强度与木本植物多样性之间的关系具有空间异质性。[结论]该研究可为城市木本植物多样性空间分布及其受城市化影响的深入研究提供科学依据。[Objective]To explore the spatial relations between urbanization intensity and woody plant diversity.[Method]Taking urban forest of Qingdao urban area as the research object, on the basis of sample survey, using SPSS software to analyze the correlation between urbanization strength and diversity index of woody plants, at the same time using geographically weighted regression model to establish the spatial relationship between them.[Result]The results showed that the diversity of woody plants in the main urban area of Qingdao had obvious spatial heterogeneity.There was a significant correlation between urbanization intensity and woody plant richness index, but no correlation between urbanization intensity and Shannon Wiener index and evenness index.The results of geographically weighted regression analysis showed that the relationship between urbanization intensity and woody plant diversity was spatially heterogeneous.[Conclusion]This study can provide a scientific basis for the in-depth study of the spatial distribution of urban woody plant diversity and its impact on urbanization.
