摘　　要：本文通过ESDA空间分析,研究1989年以来长三角县域农民人均纯收入格局的时空演变及其特征。结果表明:(1)1989年以来长三角县域农民人均纯收入绝对差异逐渐拉大,而相对差异呈阶段性波动降低态势;(2)农民人均纯收入水平呈较强的空间正相关,收入水平相似的地区在空间上集聚;(3)农民人均纯收入增长格局表现为更多的不稳定性,增长热点和冷点区存在跃迁现象,地理位置切换较为频繁,除收入增长次冷区外,各增长类型区的空间集聚趋势增强,随机分布态势减弱。最后,文章得出结论并进行了相应讨论,给出了缩小长三角区域差异,促进区域整体协调发展的相关建议。Using ESDA spatial analysis, this paper researches the spatial pattern evolution and characteristics of per capita net income of farmers in the Yangtze River Delta counties since 1989. The results show that： （1） the absolute difference in per capita net income of farmers is gradually widening, while the relative difference is decreasing with periodic fluctuations; （2）the level of per capita net income of farmers has a strong positive spatial correlation, and the regions with similar income levels have a spatial agglomeration; （3）the growth pattern of per capita net income is proved to be more instable, where its growth hot spots and cold spots switch frequently in their geographical locations, showing the existence of transition phenomenon. Apart from subordinate revenue growth cold spots, trend of spatial concentration enhanced while tendency of random distribution weakened in other growth type areas. Finally, this paper reaches some conclusions and conducts some corresponding discussions. Besides, related suggestions are given to narrow regional differences in yangtze River Delta counties and promote the regional coordinated development.
