Spaces & Flows: Ninth International Conference on Urban and ExtraUrban Studies

Abstract

The paper evaluated the urban park accessibility by the method of Gaussian based two-step floating catchment area (2SFCA), which was combined with the sixth census and city planning data, and analyzed the dynamic mechanism which affects park accessibility. The results showed that the high accessibility area was always concentrated in the south, west, and east of the city, and had a small proportion; however, the surrounding area had a large proportion of accessibility. Over the past ten years, the population has undergone substantial growth with the city expanding to the east, southeast, and south of Changchun. However, the population density has not changed much and always shows a circle of characteristics of a high center area and low surrounding distribution. The dynamic mechanism of the evolution of urban park accessibility was analyzed looking at population distribution and the number, area, and space position of parks which were the main factors affecting accessibility. It also looks at new urban park land which was not enough to meet the needs of urban residents, resulting in poor accessibility in most areas. There was no match between population density distribution and the distribution of new parks in cities which was affected by the direction of urban expansion, resulting in small changes of accessibility values but large differences.
