摘要
人均公园绿地面积是反映人民美好生活需求的重要指标之一,探明其在市域尺度上的分布特征,对推动我国人居环境建设具有重要意义。城市群是区域协同发展的代表,其公园绿地与人口的深度融合是推进城镇化绿色发展的重要任务。该文以20个城市群为研究单元,结合数理统计、空间分析法,探究1996年-2016年城市群人均公园绿地面积区域差异特征。结果表明:①时空分布上:整体发展优势明显,呈国家级→区域性→地区性的层级递减格局;②差异变化上:相对差异逐渐缩小,但绝对差异仍然显著,地区性内部差异及波动程度最高;③差异分解上:不同层级组内差异是造成总体差异的主因,其中,国家级组内差异贡献率最大且不断增强。以期为优化跨区域绿地协调、缔造美丽宜居环境提供理论依据。
Urban park green space per capita is one of the important indicators to reflect the people’s needs for a better life.It is of great significance for promoting the construction of the human settlements environment in our country to find out its distribution characteristics on the scale of the city.Urban agglomeration is the representative of regional coordinated development.The deep integration of park green space and population is an important task to promote the green development of urbanization.Taking 20 urban agglomerations as research unit,combining with mathematical statistics and spatial analysis,we explore the regional difference characteristics of urban park green space per capita from 1996 to 2016.The results show that:①The distribution of space-time:the overall development advantage is obvious,showing a national-level regional and regional hierarchical decline pattern.②The difference of variation:the relative difference decreased gradually,but the absolute difference was still significant,the regional internal difference and the degree of fluctuation were the highest.③The difference of decomposition:intra-group difference at different levels is the main cause of overall difference,among which,the contribution rate of national-level group is the largest and increasing.We hope it can optimize cross-regional green space coordination,create a beautiful and livable environment,so as to provide a theoretical basis.
