摘要
基于乡镇单元人口普查数据以及相应年份的城乡建设用地数据,运用空间分析和统计分析方法,尝试分析城镇—农村尺度江苏省流动人口分布格局的时空演变特征,并揭示驱动人口流动的动力机制。结果表明:(1)规模分布特征是具有较长大值右尾部的正偏分布,总体的集聚趋势增强,城镇和乡村集聚流动人口差距变大;(2)空间呈现高值集聚特征,热点区主要集中在长江以南的城镇,沿江地区流动人口高密度区域逐渐连绵化;(3)增长变化呈现长江以北地区城镇的流入人口增加、农村的输出人口减少,以及长江以南地区城镇的流入人口快速增加、农村的流入人口普遍增加的特征;(4)经济发展水平差异、乡镇企业繁荣、交通可达和政策导向是影响江苏省流动人口集聚的四大动力。
China has witnessed unprecedented urbanization over the past decades. With the rapid increase of the number and influence of floating population in China, it is urgent to understand the spatial characteristics of China＇s floating population. Since the reform and opening up, the migration of floating population from rural to urban area, which rebuilds China＇s urban size system, is being mirrored in China. And there was a large gap of floating population among urban and rural. The rapid expansion of urban population has been dominated by the floating population from rural areas, of which the spatiotemporal patterns, driving forces, and multidimensional effects have been scrutinized and evaluated by voluminous empirical studies. Based on the data of population census and urban and rural construction land extracted from remote sensing images in corresponding years, this paper tries to analyze the temporal and spatial features of the evolution of floating population distribution pattern in Jiangsu Province at the scale of cities and rural areas by using spatial analysis techniques and statistical analysis methods, and reveals the driving mechanism of population flow.
