近20年福州市人口与经济重心演变轨迹分析

运用重心计算方法,利用福州各县市1988-2009年年末人口、经济等数据,计算出福州市各年人口、GDP、产业重心坐标、迁移方向及移动距离,定量地表示这一时期人口、经济区域差异的动态变化.结果表明:福州市人口分布和经济发展呈现不均衡性,人口重心总体向东南缓慢移动,经济重心有明显向东南方向迁移的趋势,且经济重心迁移的幅度远远大于人口重心.从产业结构上来看,第二、第三产业重心的迁移轨迹与经济重心相近,第一产业重心的迁移轨迹则表现为较不规则.

Evolvement Track Correlation Degree Contrast of the Population Gravity Center and the Economy Gravity Center in Recent Twenty Years in Fuzhou City

By using gravity calculation method and the 1988--2009 population and econom- ic data of Fuzhou cities and counties, to calculate Fuzhours population, GDP, industrial gravity center coordinates, migration direction and moving distance of every year. Then quantitatively displays that the dynamic change of population and regional differences of economy of Fuzhou in this period. The results show the unbalanced relationship between its population distribution and economic development. The population gravity center is slowly moving to southeast, while the e- conomic gravity center is obvious heading toward southeast and faster than the former one. From industrial structure perspective, the migration track of secondary industry and tertiary industryrs gravity center are close to the migration track of economic gravity center, while the migration track of first industry＇s gravity center is more irregular.
