Muiti-scale Evaluation of Urban Green Space Based on Muti-source New Data: Exploration of Main Cities in China

The scientific evaluation of urban green space provides data support for green space planning, and it plays an important role in building sustainable and healthy city. This paper develops an indicator system for evaluating the urban green space under the new data environment, from the perspectives such as shape, quality, vitality, and service level. Then based on the theory of “Big Model”, the paper carries out multi-scale assessments of the green space in central area of 287 Chinese cities, and take Zunyi as a case study of evaluating the quality and vitality of urban green space. To make the research more objectivity, unity, and comparability, we solved several key issues including the extraction of spatial data of urban green space, and the definition of central city. The results show that: At the scale of green patch, the overall compactness of urban green space is high, and most green spaces are located near the city center. At the urban scale, the average service level of urban green space of 287 Chinese cities is 57.45%, while the sub-provincial cities have the highest average service level, and the prefecture-level cities have the lowest service level. This paper analyzes the shortages and problems of the national urban green space in the country in order to provide reference for the construction of urban green space in the future.
