Analysis and Optimized Location Selection of Comprehensive Green Space Supply in the Central Urban Area of Hefei Based on GIS

Urban parks and green spaces are essential for improving the urban environment and enhancing ecological conditions. In this study, we utilize Geographic Information Systems (GIS) as a foundation to comprehensively evaluate the overall condition of park green spaces in Hefei city, taking into account factors, such as quantity (including area), quality, and accessibility. Additionally, we propose corresponding optimization site selection schemes. The results indicate that (1) the parks and green spaces in the central urban area of Hefei city are more accessible in the southern and western parts, while they are less accessible in the northern and eastern parts; (2) the green spaces in the Shushan area are not closely connected, and the parks are not developed in a related manner. In the Yaohai and Baohe areas, green spaces are in conflict, and the parks are developing at a slower pace. However, in the Luyang area, park green spaces are integrated and positively developed; (3) it is suggested that five new parks are added to the research area, and the locations of the newly added parks should be consistent with the results of the accessibility analysis, so that the selected locations are more reasonable.
