【摘要】：本文以我国31个省份马铃薯播种面积数据为基础,运用标准差椭圆、标准距离、综合比较优势模型等方法,对1982—2015年我国马铃薯种植空间格局的变化特征及其驱动因素进行了分析。结果表明:(1)我国马铃薯空间格局经历了缓慢南移(1982—1994年)、向东北移动(1994—2000年)、向西移回(2000—2008年)和向西南快速移动(2008—2015年)4个阶段。(2)受马铃薯生产区域格局变化影响,我国马铃薯种植重心沿"西南-东北-西南"的轨迹移动,总体呈现"由北向南、由东向西"的趋势。(3)我国马铃薯种植区域逐步向西南和西北方向集聚,集聚性增强,并且集聚区域持续向西南移动。(4)效益增加、政策推动、技术进步和适宜气候是我国马铃薯种植空间格局演变的主要驱动因素。
[Abstract]:Based on the data of potato sown area in 31 provinces of China, the methods of standard deviation ellipse, standard distance and comprehensive comparative advantage model are used in this paper. The characteristics and driving factors of potato planting spatial pattern in China from 1982 to 2015 were analyzed. The results showed that: (1) the potato spatial pattern in China experienced four stages: slowly moving southward (1982-1994), moving to northeast (1994-2000), moving westward (2000-2008) and rapidly moving southwest (2008-2015). (2) it was influenced by the change of potato production regional pattern. The center of gravity of potato planting in China moves along the track of "southwest-northeast-southwest", and generally shows the trend of "from north to south, from east to west". (3) the potato planting area in China gradually gathers to the southwest and northwest, and the agglomeration becomes stronger. And the agglomeration area moved to the southwest continuously. (4) the main driving factors of the evolution of the space pattern of potato planting in China were the increase of benefit, the promotion of policy, the advancement of technology and the suitable climate.
