摘要
基于人口普查资料,对20世纪末中国迁移人口在不同行政级别、不同规模城市的分布格局进行分析,并运用探索性空间数据分析技术进一步对地级及以上城市迁移人口的空间分布特征进行研究。结果表明:地级及以上城市在迁移人口流动中占主要地位,其中百万规模级别以上城市在人口迁移中地位尤为显著;县级市间迁移人口规模差异显著,东部地区县级市平均迁移规模要大于西部和中部;省际迁移中城市空间分布大体呈现3个梯状层次;省内迁移中城市空间分布总体表现出极大的相似性,均以各省会城市作为省内迁移人口的第一流入地;不论是省内迁移还是省际迁移,东部沿海地区的珠三角和长三角地区城市群都是迁移人口的高度集聚地。
China is being at the stage of rapid urbanization.Based on the fifth census data,this paper analyzes the migration structure of China in different administrative and scale cities in the 1990s.The result shows that it is the prefecture cities that plays important role in the Chinese population migration in the 1990s,in which the big cities,especially the mega-cities,take a more significant position.It is also found that there are differences in the migration scale between county-level cities.The average migration scale of county-level city in East China is more than in West and Middle China.For the prefecture and above level cities is more important in the process of China′s urbanization at present and in the future,this article further examines the patial distribution pattern of inner-provincial and inter-provincial migration.It is showed that there are three ladder-like levels for prefecture cities in the spatial distribution pattern of inter-provincial migration： the first level includes the Zhujiang River Delta agglomeration,Changjiang River Delta city group,west bank cities,Beijing-Tianjin-Henan city agglomeration,the core cities of Liaodong Peninsula and a few of provincial capitals in middle-west area.The second level includes most of provincial capitals in middle-west area： Shandong Peninsula urban agglomeration and other eastern cities which are close to Beijing-Tianjin-Henan area,Changjiang River and Zhujiang River.The third level includes other provincial cities of middle west area and other cities which are far away from the core cities of three metropolises in the eastern area.Besides,the circle structure is obvious in the southeast coastal area,while the peak structure is more evident in the mid-west area.With regard to the spatial distribution pattern of inner-provincial migration,it shows that there are great similarities among prefecture-level in population spatial distribution pattern.The first gathering cities are each provincial capital cities.The ESDA technology is used to study the spatial distribution features of migration in cities in China.The result shows strong concentration for spatial distribution.The Zhujiang River Delta agglomeration,Changjiang River Delta city group are the main gather cities in both of inner and inter provincial migration.Furthermore,the migration gathering city range in Zhujiang River Delta area is larger than the Changjiang River Delta.On the contrary,the cities with small migration scales are located in agricultural provinces such as Anhui,Henan,and Sichuan,etc.
