摘要:

探究功能多样性如何影响商圈活力,可为城市用地功能结构优化调整和商圈功能改造提供理论支撑,进而促进城市混合功能有序开发、提升城市活力。已有关于功能多样性与活力的研究,大多集中在城市、街道活力等方面,对于商圈活力研究很少涉及,且大多利用单一的熵指数反映功能多样性。在利用夜光数据对活力的研究中,大多选取城市或更大区域尺度作为研究单元,无法精准地从多角度、多层面理解功能多样性与城市内部活力的关系。因此,本文以广州市主城区为例,以商圈作为基本研究单元,融合城市设施兴趣点(Point of Interest, POI)和珞珈一号夜间灯光数据,利用希尔数模型从多维视角测度商圈功能多样性特征,并以此来探究其与商圈活力的定量化关系。主要结论如下:① 仅用熵指数来反映多样性是不足的,其与商圈活力在0.1的显著性水平下无相关性,需结合希尔数多样性指数从多视角度量商圈功能多样性,以弥补单一熵指数测度方法的不足;② 广州商圈功能丰富度指数与其活力净相关系数为0.382,提高功能丰富度以增加商圈各功能间互补性、异质性或混合性,从而具备足够的功能多样性,促进各类功能间的协同与竞争,形成良好的兼容性混合,以更好的满足多数人的消费需求,激发商圈活力;③ 广州商圈规模效应与其活力净相关系数为0.507,对比大于集聚效应的0.371,表明广州商圈发展遵循新经济地理学的规模报酬递增规律,即商圈规模越大对于提升商圈活力的效用越大,而商圈功能集聚度对于提升商圈活力的效用相对较小。

Abstract:

As the most active area of urban economic and social activities, business district provides a complex and mutually supporting diversity of functions to meet people's needs. Exploring how the functional diversity affect the vitality of business districts can provide theoretical support for the optimization and adjustment of urban land use functional structure and urban renewal, and then promote the mixed-use development and enhance its vitality. Taking the main urban district of Guangzhou as an example, this paper used Point of Interest (POI), google satellite images, high-resolution night light data of luojia No.1, spatial grid method, and hot spot analysis method to quantitatively identify the boundary range of business districts. At the same time, 28 business district were identified on the basis of comprehensive consideration of transportation railways, rivers, mountains, and historical development factors. Taking the business district as the basic research unit, the functional diversity of multiple and multi-dimensional features of the business district was measured using the Hill number model, and then the brightness of the corrected luminous radiation was calculated to represent the vitality of the business district. Finally, the method of partial correlation analysis was used to explore the relationship between single entropy index and functional diversity index with business district vitality. The main conclusions are as follows: (1) It is not enough to use entropy index only to reflect diversity, and it needs to combine with Hill number diversity index to measure the functional diversity of the business district from multiple perspectives to make up for the deficiency of the single entropy index measurement method. (2) The functional diversity index of the business district has a certain effect on business district vitality. Improving the functional richness index of the business district can help increase the complementarity, heterogeneity or mixing of functions, and to have enough diversified functions to stimulate the vitality of the business district. (3) The scale effect of business district can enhance its vitality more than agglomeration effect. The larger scale of the business district, the more stimulating on the vitality, while the functional agglomeration effect of the business district has relatively little effect on improving its vitality.
