| 摘 要： | 人口城镇化的快速推进与生态城镇化的建设滞后是中国快速城镇化进程中面临的重要问题。以长三角地区城市人口与绿地面积为研究对象,构建城市人口-绿地面积异速增长模型分析2000—2018年两者关系的时空变化规律,并运用地理探测器模型揭示异速增长的驱动机制。结果表明：① 长三角地区城市人口呈加速增长态势,绿地建设增长缓慢,城市人口-绿地面积异速关系逐渐由人地基本协调型转变为人口扩张弱型,2000—2008年多数城市表现出绿地扩张的特征,2009—2018年则转变为人口扩张的特征。② 教育投入度、人口集中度、设施供给度、土地开发度和对外开放度是影响长三角地区城市人口-绿地面积异速增长的主要因子,双因子交互解释力均高于单因子,各因子间的影响具有协同增强的特征。③ 长三角地区城市人口-绿地面积异速增长是行政力、市场力和外资力共同驱动的结果,三种驱动力彼此联系、协同作用,主导驱动力逐渐由行政力转变为市场力。

| Abstract: | The rapid development of population urbanization and the lag of ecological urbanization are major problems in the process of China's rapid urbanization. This paper, taking the urban population and green space area in the Yangtze River Delta (YRD) as the research object, constructs an urban population and green space area allometric growth model to analyze the spatial and temporal variations of the relationship between the two from 2000 to 2018, and uses the geographic detector model to reveal the driving mechanism of the allometric growth. The results show that: (1) The urban population in the study area is increasing rapidly, while the green space construction land is growing slowly. The allometric relationship between urban population and green space area in the region has gradually changed from the coordination of human and land to population expansion. Most cities are characterised by green space expansion from 2000 to 2008, but by population expansion from 2009 to 2018. (2) Education input, population concentration, facility supply, land development, and external development degree are the main factors affecting the allometric growth of urban population and green space area in the YRD. The interactive explanatory power of the two factors is higher than that of the single factor, and the influence among the factors is characterized by synergistic enhancement. (3) The allometric growth of urban population and green space area in the YRD is the result of the joint drive of administrative force, market force and foreign capital. The three driving forces are interrelated and synergistic, and the leading driving force is gradually transformed from administrative force to market force. |
