基于GIS的经济重心迁移研究——以金华市为例

Study of the Migration Economy Gravity Center in Jinhua City Based on GIS

在GIS技术支持下,对重心及经济重心概念的理解上,分析了经济重心的技术路线,并通过经济重心模型的应用,着重对1999～2008年金华市经济重心迁移特征进行研究,最后基于行政区划体制的视角分析了经济重心迁移的原因。结果显示,金华市的经济重心总体接近几何中心,经济重心自西向东方向迁移的趋势明显,经济重心移动轨迹呈现出一定的曲折和波动。

The paper using GIS technology,based on the meaning of the concept of gravity and economy gravity center,analyzing the technical route of migration research of gravity center.Based on economy gravity center model,this paper makes emphases on the study of the characteristics of the migration of economy gravity center from 1999 to 2008 in Jinhua city.At last,based on view of the system of administrative division,analyzes why the economy gravity center migrated.The results show that the economy gravity center approaches the geometry center in Jinhua city,the trend that economy gravity center moves from west to east is obvious,and the migration orbit of economy gravity center demonstrates certain fluctuation.
