摘要:

选取2004、2008、2012年人均农业收入数据，运用GIS空间分析方法，从时间、空间角度研究广西县域农民农业收入差异及变化。结果表明：（1）广西中部以较高、高收入县域为主，且空间形态长期呈“/”形状，较低、低收入县域集聚东、西两侧。（2）2004年以来，较高收入、高收入县域数量并未显著增加，仍以中低收入县域为主。（3）收入等级相同或相近的县域空间集聚现象有所减弱，但中间高、两侧低的整体格局仍然存在，无明显空间变迁。（4）农业收入热点区形成南宁、柳州“双核心”模式。热点区域缺乏对冷点集聚区的“飞地”支持。（5）北部湾经济区农业收入最具竞争力，县域空间分布无明显差异； 桂西资源富集区农业收入出现局部热点，但南高、北低格局将长期存在； 西江经济带农业收入问题较为严重。（6）地理位置、农业细类结构与农业新经营方式采用、区域发展战略等因素成为农业收入时空变化的重要驱动力。

Abstract:

Based on the data of per capita farmers' income in 2004， 2008 and 2012，this peper studied the income inequalities and changes from spatial and temporal aspect using the GIS mothod. Results showed that：1）Middle area of Guangxi was dominated by the top income counties and the above average levelthat showed a"/"shape for a long time.2）The number of the top income counties did not increase significantly，low income counties were still dominating.3）There was no significant spatial change for the counties that have same or similar income level, the pattern of"middle higher and sides lower"still existed.4）Nanning and Liuzhou were the Hot-spots of high income.5）Beibu-Gulf Economic Zone had the most competitive agricultural income；agricultural income hot spots appeared in the resource-rich region of western Guangxi，the distribution of "higher income in the south，lower in the north"will exist for long； West River economic Belt was facing severe income problems.6）Location，structure of agriculture subcategories, the adoption of new operation modes，and the regional development strategies were the important driving forces for improving the agricultural income.
