Research on the accessibility of park green space based on GIS technology in Jinan City

Efficiency of urban green space has become an important indicator of urban influence and living standard,of which the spatial accessibility is the core.Traditional studies on the accessibility of park green space have some limitations,which consider only straight-line distance from the park,not involving the actual line to the park,nor taking into account the actual circumstances surrounding the park.In this paper,an analysis is made of the spatial accessibility of park green space in Jinan City parks and the corresponding greenbelt construction scheme is put forward by using GIS technology and cost weighted distance method.The results show that the accessibility of park green space is more reasonable according to the accessibility analysis based on the relative resistance while the accessibility is unreasonable according to the analysis based on the integrated resistance value and that the regions of unreasonable accessibility are distributed in the west and north of the central city.
