基于GIS的经济与产业重心空间演变及动态分析*——以福州市为例

Spatial Evolution and Dynamic Analysis on Economic Barycenter and Industrial Centre of Gravity in Fuzhou Municipality Based on the GIS

运用GIS手段对福州市1968~2009年40a来经济和产业重心变化轨迹进行研究,揭示福州经济发展的变化特征。结果显示：在研究期间内福州市的经济和产业重心40a来均有不同程度的迁移,而且都偏离福州市的几何中心;分别从横向和纵向来分析福州经济和产业重心变化的关系,发现它们之间的变化幅度和趋势基本相同;从重心年平均变动速度进行分析,表明年平均迁移速度变化最小的是第三产业,变化最大的是第二产业。

By using the method of GIS,the research was conducted on the change track of economic barycenter and industrial centre in Fuzhou from 1968 to 2009,so as to reveal the variation characteristics of Fuzhou economic development.The results show that the economic barycenter and industrial centre of gravity migrated at various degrees in Fuzhou Municipality,and all deviated from the geometric center of Fuzhou during these forty years.In addition,it was analyzed the relationship between the economic barycenter and industrial centre of gravity changes in Fuzhou from the horizontal and vertical aspects respectively.It is found that the extents and trends of changes is basically identical.In the end,the research analyzed the average annual change speed of the barycenter,it is showed that the third industry had the minimum change,and the second industry had the biggest change.
