需求导向下合肥市公园绿地空间布局研究

Research on the Spatial Layout of Green Space in Hefei City Park Under Demand Orientation

立足主体需求的视角,采用GIS空间分析方法,剖析合肥市公园绿地的分布格局特征,探究公园绿地空间配置水平。结果表明:研究区域内公园绿地总体呈现“核心-边缘”圈层式的空间分布格局,各类型公园的空间分布形态差异显著;整体上公园绿地表征为显著性聚类的空间聚集格局,其中居住区公园的聚集格局表现为显著聚类,综合公园和区域公园则为随机分布;研究区域内近30%的居住小区不在公园绿地的服务覆盖范围内,各类公园的覆盖范围存在较大差距;公园绿地同小区的平衡协调关系具有较强的空间异质性。通过探析公园绿地的空间布局特征,以期为同类型城市绿地系统规划提供支撑。

Based on the perspective of subject needs,GIS spatial analysis method is adopted to analyze the distribution pattern characteristics of park green spaces in Hefei and explore the spatial allocation level of park green spaces.The results indicate that the overall spatial distribution pattern of park green spaces in the study area presents a“core-edge”circular pattern,with significant differences in spatial distribution patterns among different types of parks;Overall,the park green space is characterized by a significant clustering spatial clustering pattern,with the clustering pattern of residential parks showing significant clustering,while comprehensive and regional parks are randomly distributed;Nearly one-third of the residential communities in the study area are not within the service coverage of park green spaces,and there is a significant gap in the coverage of various types of parks;The balance and coordination relationship between park green spaces and residential areas has strong spatial heterogeneity.By analyzing the spatial layout characteristics of park green spaces,the support for the planning of urban green space systems of the same type is provided.
