摘　　要：城市公园绿地是城市的重要组成部分,能够发挥生态效益、提升人居环境、促进城市可持续发展,但当前公园绿地配置更关注人均指标的设置,忽视了城市中设施配置的公平性。基于环境正义视角,借助GoogleMap与网络大数据,运用GIS分析合肥市建成区城市公园绿地与低收入人群、老年人群等弱势群体的空间分布模式,并通过高斯两步移动搜索法计算城市公园绿地空间的可达性,进而研究公园绿地的公平性。结果表明:低收入人群在劳动密集型产业区和租金低廉住房区集聚,老年人群在老城区和高密度社区集聚。城市公园绿地的空间分布呈现“多中心、组团式”的空间分布特征。总体而言,合肥建成区2类人群公园绿地公平性有着明显的空间分异特征,公平性有待提高。最后结合实际从5个方面提出城市公园绿地布局优化建议。Urban park green spaces are an important component of cities,which can play an ecological role,improve the living environment,and promote sustainable development.However,the current allocation of park green spaces focuses more on the setting of per capita indicators,neglecting the fairness of facility allocation in cities.Based on the perspective of environmental justice,utilizing GoogleMap and big data,the spatial distribution patterns of urban park green spaces in the built-up areas of Hefei are analysed by using GIS,as well as vulnerable groups such as low-income and elderly populations.The accessibility of urban park green spaces is calculated using the Gaussian two-step mobile search method,and the fairness of park green spaces is further studied.The results indicate that:low income populations cluster in labor-intensive industrial areas and low rent housing areas,while elderly populations cluster in old urban areas and high-density community areas.The spatial distribution of urban park green spaces presents a“multi center,clustered”spatial distribution characteristic.Overall,there is a clear spatial differentiation in the fairness of park green spaces for two types of people in the built-up areas of Hefei,and the fairness needs to be improved.Finally,according to the actual situation,the optimization suggestions of urban park green space layout from five aspects are put forward in the paper.
