Abstract
Taking the park green space in Weidu District of Xuchang City as the research object, the spatial service area of the park green space under the mode of pedestrian transportation is analyzed by using the grid analysis function of geographic information system (GIS). The results show that under the walking mode in the research area, only less than 1/10 of the residents can walk to the park within 10 minutes, and nearly 1/5 of the residents can enjoy the service function of urban park green space within 20 minutes. Under the walking mode of 30 minutes, the accessibility area of park green space is only 36.63%, which is mainly concentrated in the new urban area. There are many urban parks with large scale. The number of urban parks in the old urban area is small and the accessibility is relatively poor. The research results can provide theoretical basis for optimizing the spatial structure of green space in Weidu District of Xuchang City.
Highlights
Urban green space is an important part of urban modernization and an important green infrastructure
It is necessary to analyze the accessibility of urban park green space in Xuchang City, find out the problems existing in the planning and put forward countermeasures, so as to provide scientific guidance for the planning and construction of park green space in Xuchang City in the later stage
Influenced by time, distance, cost and other factors, it can objectively reflect the rationality of the spatial layout of urban park green space, and it is an important index to evaluate whether residents can enjoy urban green space fairly and conveniently [8]
Summary
Urban green space is an important part of urban modernization and an important green infrastructure. Influenced by time, distance, cost and other factors, it can objectively reflect the rationality of the spatial layout of urban park green space, and it is an important index to evaluate whether residents can enjoy urban green space fairly and conveniently [8]. Urban Park Green Space System of Weidu District of Xuchang City is taken as the research object, the database based on urban road system and urban park green space is established by using GIS grid analysis function, the problems existing in the accessibility of urban park green space under three different time modes of walking 10min, 20min and 30min are analyzed, and the optimization strategy is put forward
