摘　　要：以汾河流域各县域为研究单元,选取1994-2013年研究区人均GDP数据,以GIS空间分析方法为基础,分别从绝对差异、相对差异、空间分异特征等角度对其20年来的经济空间分异态势进行分析。结果表明：汾河流域县域经济发展两极分化态势明显;太原市作为区域核心,对周边县市的辐射带动作用逐渐减弱;流域中部经济发展速度较快,以孝义市为核心,依靠资源禀赋以及交通区位条件等,经济增速明显,成为新的高值聚集区;流域南部缺乏明显的中心城市,临汾市作为汾河流域南部人口最为集中的城市,但其经济发展相对较慢,对周边县域的辐射带动能力较弱,作为局部核心城市的作用不显著。With counties of Fen River valley as the study area,selecting GDP per capita during 1994- 2013,based on GIS spatial analysis method,economic spatial differentiation in recent 20 years were analyzed from perspectives of absolute difference,relative difference,spatial differentiation characteristics. The results showed that： the phenomenon of polarization is obvious in economic development of counties in Fen River valley;as the core of the region,the radiation and driving function of Taiyuan to neighboring county has been weakened gradually; the speed of economic development in middle part of Fen River valley is faster,depend on its endowment of resources and specific geographic position,the economic growth is apparent and become the new high value accumulation area; the south part of Fen River valley is short of core city,as the most population concentrated city in this area,the economic growth of Linfen is relatively slow,and lack the radiation and driving function to neighboring area,and can not play the role of core city in this area.
