Analysis of Walking Accessibility of Park Green Space in Weidu District of Xuchang City Based on GIS

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.

Study on the Spatial Arrangement of Urban Parkland under the Perspective of Equity—Taking Harbin Main City as an Example

“…In urban and transportation planning fields, the network analysis method is commonly used to assess the service coverage of public facilities, the efficiency and accessibility of transportation networks, and other issues [26]. Using network analysis to grade the accessibility of parkland and assign values to each level, conclusions can be drawn about the spatial accessibility of parkland for walking traffic, public transportation, and cycling traffic modes [27]. Network analysis is an analytical and computational method that utilizes network topological relationships, spatial and attribute data, and mathematical theoretical models for multifaceted studies.…”
