| 摘 要： | 由于城区土地资源的稀缺性,公园绿地的供给与人口对绿地的需求往往难以匹配,出现了公园绿地空间分布不均衡和服务不公平性的现象。本文以两步移动搜索法的可达性测度为基础,开展武汉市主城区公园绿地社会公平性的时空分析研究。研究表明:新一轮规划实施后,从服务的整体效益来看,武汉市主城区公园绿地资源分配向着更趋于公平的方向发展;从公园绿地服务的空间格局来看,绿地可达性提高较为显著,可达性极低区域面积减少。

Spatial-temporal Analysis of Green Space Service Equity Based on Accessibility |
| |
| Abstract: | With regard to green space for urban parks,the supply often fails to satisfy the demand due to scarce land resources in the urban area.This paper gives a spatial-temporal analysis on social equity of green space for parks based on the accessibility measure set out in the two-step floating catchment area (2SFCA) method.The paper draws on my comparative research on service equity before and after the implementation of a new green space plan in the main urban area of Wuhan City.According to the research,green space resources for parks in the area tend to be more fairly allocated.In addition,accessibility of green spaces improves significantly while areas with very low accessibility reduce after the implementation. |
