摘要
城市公共绿地空间分布的合理性和公平性对居民生活和生态环境有重要意义。以武汉市中心城区为例,借助多源数据从供需平衡视角对城市公共绿地进行识别分类,采用重力型两步移动搜索法和空间公平性评价模型测度居住小区尺度的城市公共绿地的空间可达性和公平性。结果表明,研究区城市公共绿地可达性形成了长江东岸高于西岸、中心高于边缘、沿江沿湖地区高于其他地区的空间分布格局。同时在沿湖地区供给饱和现象严重,在人口密集未更新改造的老城区供给相对不足。
The rationality and fairness of the spatial distribution of urban public green space are significant to the quality of routine life and ecological environment.Taking the urban center of Wuhan as an example,from the perspective of supply and demand balance,we extract urban public green space based on multi-source data,and assess the spatial accessibility and equity of public green space using gravity two-step floating catchment area method and integrated spatial equity evaluation model from the residential quarter scale.The results show that the accessibility of urban public green space in the east bank of the Yangtze River is higher than the west bank,the central and lakeside area is higher than other areas.The supply saturation of green space is serious in the lakeside area,while the supply is relatively insufficient in the densely populated old towns that have not been renovated.
