摘要
基于2009~2019年全国城市统计年鉴数据,采用统计法和空间自相关分析,分析东北地区城市建成区面积的时空分布特征,并采用地理加权回归(GWR)分析其主要影响因素.研究结果表明:全局Moran’s I指数表明,东北地区的城市建成区面积一直处于空间离散的状态.利用地理加权回归(GWR)分析城市建成区面积影响因素,得出城市建成区面积与人口的回归系数,随东北地区的东北部向西南部,数值由负数到正数;与地区生产总值呈正的相关关系,但不足以说明其显著性;与第一产业占GDP的比重间关系相反;与第二产业占GDP的比重呈正的相关关系;与第三产业占GDP的比重呈负的相关关系.
Based on the national urban statistical yearbook data from 2009 to 2019,using statistical methods and spatial autocorrelation analysis,the spatiotemporal distribution characteristics of urban built-up area in Northeast China is analyzed,and using Geographically Weighted Regression(GWR),its main influencing factors are analyzed.The research results indicate that:The global Moran's I index indicates that the urban built-up area in Northeast China has always been in a state of spatial dispersion.Using Geographically Weighted Regression(GWR)to analyze the influencing factors of urban built-up area,the regression coefficient between urban built-up area and population is obtained.As the northeast of the northeast region moves towards the southwest,the value changes from negative to positive.There is a positive correlation with the regional gross domestic product,but it is not sufficient to indicate its significance.The relationship between the proportion of primary industry and GDP is opposite.There is a positive correlation with the proportion of the secondary industry to GDP.There is a negative correlation with the proportion of the tertiary industry to GDP.
