Embodiment 1

[0082] This embodiment adopts an application example, taking the living area in the center of Guangzhou, Guangdong Province as the research object for practice, including some areas of Yuexiu District, Tianhe District, and Haizhu District, with a total area of ​​37,363 hectares. This area includes the old center and the new center of Guangzhou. Its relatively prosperous status since ancient times makes it a good choice for urban vitality analysis.

[0083] Such as figure 1 As shown, this embodiment provides a method for measuring the correlation between urban vitality and spatial social characteristics based on big data, which specifically includes the following steps:

[0084] 1) Within the scope of the study, the urban area is divided into several blocks according to the traffic network as the basic spatial analysis unit.

[0085] 1.1) According to the road network downloaded from the OpenStreetMap open map platform and the current urban traffic road network, the main roads...

Embodiment 2

[0147] A measurement system for the correlation between urban vitality and spatial social characteristics, including: a division module, an urban vitality indicator building module, an urban form indicator building module, an urban function indicator building module, a socioeconomic characteristic indicator building module, a multiple regression model building module, Correlation measure output module;

[0148] In this embodiment, the division module is used to divide the urban area into multiple blocks according to the traffic road network as the basic spatial analysis unit;

[0149] In this embodiment, the urban vitality index construction module is used to obtain population grid data and calculate the block population density parameter as an index to measure urban vitality;

[0150] In this embodiment, the urban form index construction module is used to obtain traffic road network data to calculate road network intersection density, road network connectivity and road networ...

Embodiment 3

[0156] This embodiment provides a storage medium, which can be a storage medium such as ROM, RAM, magnetic disk, optical disk, etc., and the storage medium stores one or more programs. When the programs are executed by the processor, the city of Embodiment 1 is realized A measure of the correlation between vitality and spatial social characteristics.

Abstract

The invention discloses an urban vitality and spatial social characteristics correlation measuring method and application, and the method comprises: taking a block obtained through road network segmentation as a basic spatial analysis unit in a certain urban range based on big data; taking the population density data as a measurement index of urban vitality; acquiring traffic network data and building vector data, and calculating to obtain a measurement index of the urban form; obtaining POI data in the range, and calculating to obtain a measurement index of the city function; obtaining population portrait data, and calculating to obtain a measurement index of social and economic characteristics; and establishing a multiple regression model of the urban form, the urban function, the social and economic characteristics and the urban vitality, thereby obtaining the correlation between the urban vitality and the spatial social characteristics. The relation between the urban vitality and the spatial social characteristics can be accurately obtained, an urban vitality evaluation system is expanded, and a guidance basis is provided for planning practice of improving the urban vitality.

Description

technical field [0001] The invention relates to the technical field of urban planning and design, in particular to a measurement method and application of the correlation between urban vitality and spatial social characteristics. Background technique [0002] Enhancing the vitality of urban space is crucial to urban development, which not only involves a high concentration of population and capital, but is also closely related to the health of residents, social development, and spatial connections. When urban space and social space do not match, the city will become monotonous and lack vitality, and even urban problems such as vacant houses, population loss, and overdevelopment will appear. The emergence of urban problems has increasingly reduced the stability of urban structures and the sustainability of urban systems, and more and more studies have used urban vitality to understand the intricate social and economic order behind large cities. The traditional data environme...
