Abstract:

Urban public green space is fundamentally important for residents’ daily life. Traditional methods for calculating service population of urban public green space often adopt administrative regions as analytical units for statistical analysis. This relies on the division of administrative units and cannot reflect population variation within a unit. This paper performed the analysis at a finer resolution with more accurate real population data within the outer ring of Shanghai. The methods and procedures were proposed to calculate the results based on raster analysis of Geographic Information System (GIS). First, with cost allocation function in GIS, service area, service population and service population per unit area were analyzed by assigning different service distances of each urban public green space. Second, no service area, population and population density in no service area were analyzed.

Key words: public green space, real population, no service area, service allocation
