摘　　要：研究区域人口空间演变,可揭示区域人口空间分布的规律性,对于制定合理的人口发展政策,促进区域的可持续发展,均具有重要意义。根据1982、1990、2000年人口普查资料,结合长江三角洲地区各市历年统计年鉴,先对本地区的人口分布空间格局进行了分析,得出各地市人口数量差异巨大、人口密度北高南低、沿交通轴线人口集中分布的特点,然后对20世纪80年代以来人口分布的动态变化特征、规律做了较细致探讨,得出各地区人口增幅存在较大差异、人口密度增长总体放缓、人口分布先集中后分散、人口重心由东北向西南移动等演变特征。并结合影响区域人口空间分布的外部因子进行解释,认为经济因素、城市地位与功能、政策因素以及信息交通等因素是造成本区人口空间结构发生巨大变化的原因。The study of regional population evolution is helpful to reveal the rule of population distribution and is important for reasonably making population developmental policy, and for the promotion of regional sustainable development. In this paper, firstly, a preliminary study was conducted on population distribution structure according to the third, fourth, fifth census materials, and all previous statistic yearbooks about all cities in the Yangtze River delta area. The population quantity of different cities is quite different, with the density being higher in the north, and with distribution concentrated along traffic axes.Then, characteristics of population distribution and regulation have been particularly analyzed since 1980s. It was shown that there are many differences among the population amplitudes in different cities, with lower increase of population density. The distribution is of concentration-decentralization pattern, and center of gravity moves from northeast to southwest. Some exterior factors affect the regional population spatial distribution. It was considered that economic factors, status and function, policy, information and traffic factors are the causations resulting in the great changes of regional population spatial distribution.
