静态空间与实际访问的城市公共绿地公平对比评估

Equity comparison between straight-line distance and actual access distance to urban public green spaces

基于OPTICS时空聚类技术和LBS轨迹大数据,文章比较静态空间关系与实际访问关系的基尼系数,并对城市公共绿地分配与访问距离进行对比评估。结果表明,静态空间关系与实际访问关系之间存在显著的公平差异,反映了公共绿地使用的空间不平衡性,城市规划需更多关注实际使用情况。

Based on the OPTICS spatiotemporal clustering technology and LBS trajectory big data,this paper compares the Gini coefficient of the static spatial relationship and the actual access relationship,and evaluates the fairness of urban public green space allocation and use.The results show that there is a significant equitable difference between the straight-line distance and actual access distance,which reflects the spatial imbalance of public green space use,and urban planning needs to pay more attention to the actual use.
