中文摘要：

农民人均纯收入是反映农村经济发展状况和衡量农村居民生活水平的重要指标。利用1985—2010年宁夏统计数据，运用Geoda095i空间分析软件、聚类分析法，从时空角度研究了宁夏农民人均纯收入增长的区域差异、演进格局及驱动机制。结果表明：初级阶段低增长速度区大部分位于宁南山区，呈“C”字型分布，该区域人口增长过快，水土流失严重，土地超载突出，工业基础薄弱；初级阶段高增长速度区位于宁夏中西部地区，该区域农业基础较好，但工业化进程缓慢；高级阶段高增长速度区集中分布在宁夏北部川区，该区域凭借引黄灌溉之利，农业高产稳产，已成为西北重要农业生产基地，二、三产业也得到快速发展。分析认为，地理区位条件、农业生产条件、不同劳务收入方式、区域政策演变是造成农民纯收入区域差异的主要原因。通过优化农业区域布局，大力调整农业产业结构，扶持壮大龙头企业，大力发展农业产业化经营，提高农民的整体文化素质等来提高宁夏县域农村居民纯收入。

英文摘要：

The farmers’ per-capita net income is one of the important indicators,which can reflect the development of rural economy,and measure household living standard of rural residents. Using statistical data of Ningxia Province,China from 1985 to 2010,applying Geoda095i and clustering analysis,the paper studied regional variation,evolution patterns and driving mechanism of the farmers’ per-capita net income growth in Ningxia. The results show as follows：Low-Low regions locate in the southern mountains of Ningxia,the distribution like a “C”,the major reasons for the social development in this region involve the rapid population growth,serious soil erosion,sever land overload,and weak industrial base. Low-High regions locate in the center-west region of Ningxia. Though the region has better foundation of agriculture, the industrialization is still slow. High-High regions locate in the northern plain of Ningxia. Relied on advantage of Yellow River irrigation and productive farmland,the area has been an important component of agricultural production bases in the northwest of China. It was found that the geography district,conditions for agricultural production,service income mode and area policy evolves account for a large part of the difference in farmer income. Ningxia should also provide major supports for rural incomes through optimizing agricultural area distribution,adjusting agricultural and industry structure by expanding leading enterprises,developing agricultural industrialization’s management,and improving the quality of farmer culture.
