摘要
该研究基于2018—2020年武汉市的地理国情监测数据,并以武汉市为研究区域,采用数量统计及空间格局分析的方法对武汉市2018—2020年的不透水面变化特点进行分析,达到对武汉市城市发展的动态了解。研究结果表明:2018—2020年武汉市的不透水面面积整体呈现逐年增加的变化规律;不透水面的空间分布均表现为由中心向外围逐渐递减,且在距中心3千米~6千米处达到最大;从空间和数量上,武汉市城市及经济发展规律相一致,即均以长江为轴心发展。
Based on Wuhan’s geographical national conditions monitoring data from 2018 to 2020,and taking Wuhan as the research area,this study uses the methods of quantitative statistics and spatial pattern analysis to analyze the change characteristics of impervious surface in Wuhan from 2018 to 2020,so as to understand the dynamics of urban development in Wuhan.The study results show that:from 2018 to 2020,the impervious surface area of Wuhan shows a change law of increasing year by year;the spatial distribution of impervious surface decreases gradually from the center to the periphery,and reaches the maximum at 3~6 kilometers away from the center;in terms of space and quantity,the law of urban and economic development in Wuhan is consistent,that is,their development both take the Yangtze River as the axis.
