摘要: 本文基于陕西省“粮食基本自给”生产目标,利用2002-2017年陕西省区县单元统计数据,分2002—2007年、2007—2012年、2012—2017年三期,基于ArcGIS空间分级法研究陕西省陕北、关中、陕南三大地区粮食生产空间格局及时空演变特征;运用对数均值迪氏指数法研究不同时期各区域粮食产量变化的影响因素,以及粮食播种面积、单产对粮食增产的贡献率。研究结论为:陕西省粮食生产异化特征明显;扩大关中地区粮食种植面积将缓解陕西粮食安全与陕北、陕南生态安全矛盾;乡村聚落空间结构、空间形态整合将促进农业现代化条件下关中地区耕地从分散破碎转向集中连片。Abstract: Facing the production goal of ‘grain basically self-sufficiency’ in Shaanxi Province, this paper firstly used the statistical data of county-level units in Shaanxi Province from 2002 to 2017, and divided the research data into three stages:2002-2007, 2007-2012, 2012-2017. Based on ArcGIS spatial classification method to study the spatial pattern and spatial-temporal evolution characteristics of grain production in Northern Shaanxi, Guanzhong and southern Shaanxi. Then it utilized the logarithmic mean Divination decomposition method to study the influencing factors of grain yield changes in different periods, as well as the contribution rate of grain planting area and yield to grain yield increase. The analytical results showed that:The spatial alienation characteristics of grain production in Shaanxi Province are obvious. Expanding the grain planting area in Guanzhong will ease the contradiction between grain security in Shaanxi Province and ecological security in northern Shaanxi and southern Shaanxi. The spatial structure and spatial form adjustment of rural settlements will promote the transformation of cultivated land in Guanzhong area from scattered and fragmented pattern to centralized contiguous conditions pattern under the conditions of agricultural modernization.
