摘　　要：选择长三角为研究区,构建生态空间质量评价体系,结合可达性分析、统计分析方法,通过人口、GDP、土地开发强度反映生态需求程度,分析生态空间质量的空间分布和生态空间满足人类需求程度的空间分异及演变特征。结果表明:(1)通过融合可达性分析、统计分析方法建立的生态空间供需平衡指数,能很好地识别生态空间供需“短板”。(2)长三角生态空间质量从北向南逐渐升高,1995—2015年生态空间质量较差的区域从各大城市中心部分扩大到城市周边地区。(3)长三角生态空间供需平衡的空间分布具有明显的时空差异,供给不足的区域主要是在经济和城市化发展较快的城市,供大于需的区域主要是在生态高质量区域。The balance between supply and demand of regional ecological space is of great significance to the ecological space management,urban high-quality development,and improvement of the human settlement environment.In this paper,the Yangtze River Delta was chosen as the study area to construct the ecological space quality evaluation.Combined with the methods of accessibility analysis and the statistical analysis,the ecological demand was reflected by population,GDP and land development to analyze the spatial distribution of ecological space quality and the pattern of ecological space which meets human needs.The main conclusions are as follows.(1)The balance index of ecological space supply and demand established by integrating accessibility analysis and statistical analysis can well identify the“short board”of ecological space supply and demand.(2)The quality of ecological space in the Yangtze River Delta improves gradually from north to south.From 1995 to 2015,the areas with poor ecological space quality have been expanding from the central part of major cities to the surrounding areas.(3)The spatial distribution of ecological supply and demand balance in the Yangtze River Delta has obvious spatial and temporal differences.The regions with insufficient supply are mainly distributed in the cities with rapid economic and urbanization development,while the regions with more supply than demand are mainly distributed in the regions with high quality ecological space.
