摘要
快速的城镇化建设为城市带来了大范围的扩张以及可观的经济效益。但同时部分地区也因发展过快产生了人口资源配置与区域发展脱节的问题,大量房屋存在空置的情况。以广东省作为研究区,结合NPP-VIIRS夜间灯光影像数据、土地覆盖利用数据及人口格网数据构建了用于评价房屋空置情况的指数。以区县为研究单元,探查了2015年广东省123个行政区县的房屋空置情况并分析其空间分布特征。结果表明广东省房屋空置程度呈现粤北>粤西>粤东>珠江三角洲的趋势,而且房屋空置存在明显的空间相关特性,高-高类聚集主要出现在深圳市及广州市部分地区,低-低类聚集主要出现在粤北省级临界处。该指数的构建为房屋空置识别提供新的视角,有助于城市化的健康可持续发展。
The rapid urbanization has lead to large-scale expansion and brought considerable economic benefits to the city.However,at the same time,nonsynchronization is observed between the spatial allocation of population and regional development,and there are a large number of vacant houses.This article takes Guangdong province as an example.We collect the NPP-VIIRS nighttime light data,land use data,and gridded population data of Guandong province.The indexes for evaluating housing vacancy are developed.Then we identify and explore the spatial distribution of housing vacancy of 123 administrative districts and counties in Guangdong province in 2015.Results show that north Guangdong has the highest degree of housing vacancy,followed by west and east Guangdong,while the area of pearl river delta has the lowest degree of housing vacancy.Besides,there are obvious spatial correlations of the three indexes of housing vacancy.High-high clusters can be found in Shenzhen city and specific areas of Guangzhou city,while the low-low clusters locate in the inter-provincial marginal zone.The indexes proposed in this article shed light on the identification of housing vacancy,and are helpful for the healthy and sustainable development of urbanization.
