基于活动空间的城市不同类型社区居民蓝绿空间品质差异研究

RESEARCH ON THE DIFFERENCES IN BLUE AND GREEN SPACE QUALITY OF RESIDENTS IN DIFFERENT TYPES OF URBAN COMMUNITY BASED ON ACTIVITY SPACE

人本导向的动态蓝绿空间品质差异研究日益受到关注。本文从城市居住分异视角切入,以南京市单位小区、传统社区、城中村、保障房和商品房小区的不同收入人群为研究对象,考察其居住地、工作地、其他日常活动地点以及主要活动路径上的蓝绿空间品质,交叉对比不同类型社区和不同收入群体获得的蓝绿空间品质差异,进而研究蓝绿空间质量对居民环境感知的影响机制。研究表明,基于活动空间测度的不同社区类型居民蓝绿空间品质差异明显,但不同收入群体蓝绿空间品质差异不显著;活动路径的蓝绿空间要素比活动地点对居民环境感知的影响更大。

Human-oriented research on dynamic blue-green spatial quality differences has received increasing attention from academic community in recent years.First,most studies focus on analyzing the fairness of residents with different incomes in accessing blue-green space,but rarely cross-discuss the blue-green space quality of residents of different community types and income levels.Second,the existing related research mostly evaluate blue-green space quality based on the buffer area of communities(residential locations)which are static and limited,but seldom compares the quality of blue-green space around the activity paths of residents.Third,the quality of blue space and green space have different effects on residents'physical and mental health,and it is necessary to measure them respectively.From the perspective of urban residential differentiation,the article takes the blue-green space quality of different income groups living in unit communities,traditional communities,urban villages,social housing and commercial housing communities in the central city of Nanjing as the research objects.The study first examines the qualities of blue-green space around the activity locations and travel paths of the research objects,and then studies the influence mechanism of blue-green space qualities on the residents'environmental perception.The study shows that,based on the measurement of activity space,the spatial contact quality,landscape ecological quality and health service quality of blue-green space show significant differences,and the advantages of blue-green space for different types of community residents shows different aspects in three quality dimensions.
