江苏新型城镇化进程下人均公园绿地面积的时空分布研究

Research on the Spatio-temporal Distribution of Park Green Area Per Capita in the Process of the New Urbanization——Taking Jiangsu Province as an Example

人均公园绿地面积作为城市绿地基础建设水平的重要评价指标,研究其空间集聚特征,能清晰了解现有公园绿地建设发展的问题,为新型城镇化绿化建设提供理论依据。本文借助空间自相关模型对人均公园绿地面积时空分布进行分析,得出以下结论:(1)点集在高值聚集处和低值聚集处趋势明显;(2)H-H类型集中在苏南地区,即苏南地区人均公园绿地面积水平为江苏领先地位;(3)部分地区在新型城镇化政策领导下人均公园绿地面积显著增长,而部分地区整体水平有所下降。

As an important evaluating indicator of the level of urban green space infrastructure,the per capi‐ta park green area can be analyzed on its spatial agglomeration characteristics to help clearly observe whether the existing park green space construction and development is balanced,and therefore providing theoretical basis for the future policy formulation of greening level construction in the process of the new ur‐banization.This paper constrcuted the spatial autocorrelation model to analyze the temporal and spatial dis‐tribution of park green area per capita,and the following conclusions are drawn:(1)The point set tends to agglomerate at high and low value clusters.(2)H-H types are concentrated in southern Jiangsu,the park green area per capita in southern Jiangsu is in a leading position in Jiangsu.(3)Under the leadership of the new urbanization policy in some areas,the park area per capita has increased significantly,and the overall level in some areas has declined.
