以镇域为研究单元,以农民人均纯收入为测度指标,基于变异系数、泰尔指数、莫兰指数方法与空间分类、ESDA等空间分析技术,分析了信阳市170个镇域农民人均纯收入的时空变化规律。结果表明,从时序特征看,变异系数除个别年份微弱波动外,整体呈下降趋势；泰尔指数在2009年之前呈现波动变化,近期呈现逐步下降趋势；莫兰指数介于0.4981~0.6095,镇域农村人均纯收入呈现较强的正向空间关联关系。总体而言,信阳市镇域农民人均纯收入在逐年提高的同时,内部之间的差异在减小且互促共进效应不断增大。从空间分异格局看,高、较高水平区主要分布在信阳市区周边,市域中部的部分区域；中等、较低水平区分布在市域北部的息县、淮滨县,市域中部的罗山县、光山县以及市域南部的新县、商城县,呈现小集中与分散并存的状态；低水平区在息县、淮滨县集中并形成大范围连绵分布区。基于研究结果,从区位因素、经济发展基础、自然条件、战略政策4个方面进行原因探讨,并提出了相应的政策建议。

Based on the indicator of rural per capita income,by the method of coefficient of variation, Theil index,Moran’ s index and spatial analysis technology,this paper aimed to investigate the spatial-temporal differentiation of rural income in Xinyang at town scales from 2005 to 2012 . From the temporal feature,the coefficient of variation showed downward trend except a few years’ slight fluctuations,Theil index showed fluctuated change state before 2009 and gradual downward trend after 2009 , and Moran ’ s index ranged from 0. 498 1 to 0. 609 5,rural per capita income presented positive spatial correlation. Overall,the rural per capita income of 170 towns increased year by year,the internal difference gradually reduced,and produced better promoting mutual effect. From the spatial classification,the towns with high rural per capita income were mainly distributed near to the downtown district of Xinyang city,other towns of high level were distributed in the middle region sporadically. The towns with common rural per capita income were distributed in many counties such as Xixian, Huaibin, Luoshan, Guangshan, Xinxian, Shangcheng,showed centralized and decentralized state of coexistence. The towns with low rural per capita income were distributed in the large-scale centralized continuous region in Xixian and Huaibin. The rea-sons of the above differences in Xinyang were analyzed from the natural conditions,traffic location,govern-ment macro policies,and economic basis,and finally relevant policy suggestions were put forward.
