快速城市化地区公共交通的空间剥夺特征研究

Spatial Deprivation Characteristics of Public Transportation in Rapid Urbanization Area

为合理评估快速城市化地区公共交通系统的公平性,改善公共交通系统的空间剥夺问题.在构建公共交通空间剥夺评价指标体系的基础上,运用SPSS对指标体系进行因子分析;基于空间分析方法获取公共交通的空间剥夺特征,并以昆明市呈贡新区为例进行验证;最后基于区域剥夺补偿原理,提出了公共交通资源的均衡配置策略.结果表明,呈贡新区的公共交通空间剥夺总体呈现'多核心+局部放射'的空间形态,公共交通的空间剥夺因子主要包括公共交通服务因子和公交线网覆盖率因子,建立的公共交通空间剥夺综合指数模型能够获取各交通小区的公共交通空间剥夺分异特征.

In order to evaluate the equity of public transportation system in rapid urbanization area, and improve the spatial deprivation of public transport system. On the basis of building evaluation index system of public transport spatial deprivation, SPSS is used to analyze factors of evaluation index system. Then spatial deprivation characteristics are gained by applying GIS and Kunming Chenggong New District is taken as an example. Finally, some allocation strategies are proposed based on the principle of the regional deprivation compensation. The results show that the mode of spatial deprivation of public transportation in Chenggong New District can be summarized as＂multi-core ＋ local radiation＂; Spatial deprivation factors of public transportation include public transport service factor and bus transit network coverage factor; The establishing comprehensive index model of public transport spatial deprivation can obtain differentiation characteristics of public transport spatial deprivation in different traffic zone.
