顾及三生空间交互特征的城市空间宜居性评价——以武汉市为例

Evaluating livability of urban space with consideration of the interactive characteristics of ecological-living-productive spaces:a case of Wuhan city

本文从三生空间功能角度出发,融合多源地理数据建立了三生空间分类指标体系,并进一步顾及空间交互特征,建立了城市空间宜居性评价体系。以武汉市为例,对武汉市中心城区的三生空间格局进行了识别,并对该区域的宜居水平进行了评价分析。结果表明:①武汉市中心城区三生空间的总体配置不均匀,空间上呈现出生活空间中心聚集、生产空间四周分散、生态空间范围大但数量较少的分布格局;②武汉市三生空间混合度较低,大部分城市空间功能类型单一;③受邻近空间的影响,武汉市中心城区中,宜居度较高的区域集中在中心城区的边缘地带。

From the perspective of the function of ecological-living-productive spaces,the classification index system of ecologicalliving-productive spaces is established by integrating multi-source geographic data,and the evaluation method of urban spatial livability is further proposed by considering the spatial interaction characteristics.This paper identifies the ecological-living-productive spaces pattern of the central urban area of Wuhan,and evaluates the livable level of this region.The results show that:①The whole distribution of ecological-living-productive spaces in the central urban area of Wuhan is uniform,showing a spatial distribution pattern of the living space center gathering,the production space scattered around,and the ecological space range is large but small quantity;②The spatial mixing degree of the ecological-living-productive spaces in Wuhan is low,spatial function types of most the urban areas are single;③Affected by the adjacent space,the areas with higher livability are located in the edge of the central urban area.
