Research on Quantitative Assessment Method of Urban Community Vitality

Back to the humanistic perspective, urban planning management in China focus more on street quality, community-building and other work to improve the quality of the city recently; in the past, the pattern of guiding urban planning to control development and construction indicators such as 10,000 people per square kilometer and other general means is difficult to adapt to the requirements of fine management and control indicators system.
Firstly, this paper defines a unified 2-3 square kilometers spatial analysis unit in four cities: Beijing, Shanghai, Guangzhou and Shenzhen, and then study the data characteristics of management and control indicators: the density of road network, bus service coverage, building density, floor area ratio and green space coverage in high-vitality areas sorted by different functional areas, such as central business districts, residential districts, development zones, old urban areas and new built-up areas.
The results of the analysis can support the following three planning and management applications: 1. Comparative study on spatial distribution structure of high-vitality areas in different cities; 2. Comparative study on sensitivity of different functional areas to different regulatory indicators; 3. Recommended values of regulatory indicators for various high-vitality functional areas in mega-cities are proposed.
The shortcomings of the study are the following three points: 1. The delimitation of spatial analysis units can be further optimized and adjusted with local management data; 2. The quantitative identification methods of different functional areas should be further studied; 3. The selection of vitality indicators and control indicators should also be supported by corresponding quantitative analysis.
