摘要
基于1980-2012年中国各地区葡萄生产的面板数据,利用区域重心分析法和GIS软件,测定并描绘了中国葡萄生产重心的变迁特征。结果表明：我国葡萄生产重心一直分布在东经102.38°~110.81°、北纬36.08°~39.9°之间;中国葡萄生产重心的变迁可以分为三个阶段,整体上呈现出向东南方向移动的趋势,移动速度趋向于平稳。
Based on China＇s grape production panel data in different regions during 1980-2012, adopted the regional center of gravity analysis and GIS software to determine and describe the track evolvement and its characters of the gravity center of grape production. The results showedth at the grape production center of gravity has been distributing at longitude 102.38°~110.81°E and latitude 36.08°~39.9°N; There were three stages in the evolvement of production gravity center, in whole the center tended to shift to the southeast, and the movement speed tended to be stable.
