Research on Application of Gradient Analysis to City Green Space Accessibility——Taking garden green space of Taian central city for instance

Abstract

Abstract Green space accessibility can be used to measure the potential of green space to provide services to residents. In this study, based on the spatial analysis function of GIS software and combining with the distribution of road network of Taian central city, gradient analysis was firstly introduced to analyse accessibility and its spatial distribution character of garden green space quantitatively. Results showed that whole accessibility of garden green space of Taian central city is good whichever transportation was adopted. Most of the regions could arrive at the nearest garden green space within 5 minutes. Accessibility of the centre area was better than that of the edge, and accessibility of the north area was better than that of the south. To some extent, there is relative between gradient distribution of accessibility and that of area of garden green space.
