【目的】根据局部气候分区(LCZ)特征揭示高密度城市中多种街区形态与绿色空间特征的复杂关系，为城市绿色空间规划管理提供科学依据。【方法】以武汉市主城区为研究对象，基于LCZ对506个控规单元的街区形态进行划分，构建城市2D/3D绿色空间指标体系；运用单因素方差分析、地理探测器等方法，深入分析不同LCZ下绿色空间指标的差异性及其影响因素。【结果】1)武汉市主城区LCZ分布具有空间自相关性，不同LCZ的绿色空间2D/3D指标差异显著。2)LCZ类型与平均斑块面积(AREA＿MN)、冠层高度标准差(SDCH)、绿容积率(GVR)3种指标具有显著相关关系。3)建成环境因素(建筑密度、平均建筑高度等)对LCZ分类影响显著，而社会经济因素(人口密度、GDP等)影响较小。【结论】1)街区形态类型通过建成环境因素主导绿色空间2D/3D指标的差异性。2)2D/3D的研究视角有助于拓展城市街区的合理规划设计，促进城市可持续发展，提升生态环境质量和居民生活品质。
Abstract：【Objective】The study aims to reveal the complicated relationship between multi-form neighborhood morphology and green space characteristics in line with the feature of local climate zone(LCZ), and provide a scientific basis for the planning and management of urban green space. 【Method】The neighborhood morphology of 506 control units in Wuhan's central urban area is classified based on the LCZ to establish a 2D/3D green space index system, and the indicators' differences and influence factors are analyzed using ANOVA and geodetectors.【Result】 1) LCZ distribution in Wuhan's central urban area shows spatial autocorrelation with significant variations in their 2D/3D green space; 2) LCZ type is strongly correlated with AREA＿MN, SDCH, and GVR; and 3) The factors in relation to the built environment(e.g., building density) have substantial influence on the categorization of LCZ, while socio-economic factors(e.g., GDP and population density) have minimal influence.【Conclusion】1) Neighborhood morphology type dominates the variation in the 2D/3D green space indicator via built environment; and 2) The 2D/3D approach advances sustainable neighborhood design, promotes sustainable urban development, and enhances the ecological and life quality.
