摘　　要：改革开放以来,随着经济社会的快速发展,浙江省各地区人口分布发生了明显的变化。文章运用空间自相关、不均衡系数、人口重心和偏移增长法,对浙江省69个县级行政单元人口分布的空间格局及其在1985-2007年间的时空演变特征进行了深入分析,并得出以下几点结论:①浙江省人口密度分布具有"点—带—区"结构特征,即以经济发展水平高的地区为高值点,通过杭甬高速和甬台温高速将各高值点连接成带,其他地区则形成人口密度低值区;②浙江省人口分布存在一定的空间关联性,在浙东北环杭州湾地区和浙东南沿海地区呈现高高集聚,在浙中和西南内陆地区呈现低低集聚;③浙江省人口呈不均衡分布状态,并且人口不均衡系数不断增大;④浙江省人口偏移增长在三大区域之间具有明显差异,浙东南沿海地区人口总偏移量为正,浙东北环杭州湾地区基本稳定、浙中和西南内陆地区为负,人口重心逐渐向东南沿海偏移。Economy is the engine of population growth. With the development of Zhejiang＇ s economy and its urbanization process, the amount of Zhejiang population is growing rapidly, and population distribution among cities has undergone significant change. In order to understand the characteristics of the spatial distribution pattern and the spatio-temporal dynamics of Zhejiang population, we use Spatial Autocorrelation, Unbalanced Coefficient, Population Gravity Center and Shift-Share Analysis to analyze the 69 cities （counties） between 1985 and 2007. The empirical results show that： （1） The, population density distribution in Zhejiang presents ＂Point-Bands-Region＂ structure that considers regiorrs at higher economic development level as high value points, links these high value points to bands by Hang-Yong and Yong-Tai-Wen expressways, and sees the other regions as low value regions. （2） The population distribution displays space correlation, and presents ＂High-high Concentration＂ around Hangzhou Bay region of Northeast Zhejiang and Southeast Zhejiang Coastal Area. （3） The population distribution is much more inbalanced and Unbalanced Coefficient increases gradually. （4） Population deviation growth among three regions has obvious differences, such as the total offset in Southeast Zhejiang Coastal Area being positive, basically stable in Hangzhou Bay region of Northeast Zhejiang and negative in the last region, and the population gravity center moving to the south of Zhejiang gradually.
