中文摘要：

基于农民收入的时序演变、结构转变与空间差异分析，应用变异系数、极差系数和GIS技术研究吉林省农民收入的整体变动情况。研究表明：1986-2003年，吉林省农民收入在经过了稳步、曲线、直线、波形增长后遭遇平台期；家庭经营性收入仍是农民收入的主要来源，年均比例占总收入的80％以上；省内各市县农民收入的高低重心发生显著变化。利用1990-2003年的数据，选取影响农民收入变动的8项因素进行灰色关联分析，发现人均耕地面积是影响吉林省农民收入的首要因素，关联度高达0．893。结合吉林省实际，对8项影响因素进行了系统分析。图3，表2，参5。

英文摘要：

Based on analysis of time series fluctuation, structural change and spatial differentials, the paper studies rural income change of Jilin province at whole level, using coefficient of variation, ratio of the max to min and geography information system. The research results show that the rural income of Jilin province represents significant fluctuation from 1986 to 2003, income from household operations is still the major source and regional gravity of high and low income is different remarkably between 1986 and 2003 in Jilin province. Choosing 8 impact factors on rural income and using the data from 1990 to 2003, the authors take the grey relation analysis and find that cultivated land per capita is the top impact factor and its grey relation degree is 0. 893. Finally, the paper provides a comprehensive analysis of the 8 impact factors on rural income of Jilin province.
