【摘要】：为分析四川省农作物的地理集聚特征,专业化格局,从农业地域系统视角构建分析框架探讨其演化机制。文章以12种农作物为研究对象,基于2000~2014年的四川省21个市州农作物播种面积数据,综合运用重心模型、基尼系数、区位熵进行研究。结果表明:(1)四川省12种农作物生产重心较为稳定,未出现较大范围的地理迁移。(2)四川省大部分农作物地理集聚水平整体较低,且在研究期内集聚过程缓慢。经济作物的区域专业化水平相对于粮食作物较好。烟叶、苹果地理集聚程度较大,已经形成相对明显的区域专业化生产。(3)农业地理集聚格局演变从最初受内部压力驱动形成自然集聚格局,逐步转向为受内外压力驱动的自然社会集聚格局。四川省主要农作物地理集聚处于试错和纠错过程中,尚未形成新一轮的农业生产区域化布局和分工。
[Abstract]:In order to analyze the geographical agglomeration characteristics and specialization pattern of crops in Sichuan Province, this paper constructs an analytical framework from the perspective of agricultural regional system to explore its evolution mechanism. Based on the planting area data of crops in 21 cities and prefectures of Sichuan Province from 2000 to 2014, using the barycenter model, Gini coefficient and location entropy, the results show that the production center of 12 crops in Sichuan Province is relatively stable. The geographic concentration level of most crops in Sichuan Province is relatively low, and the accumulation process is slow during the research period. The regional specialization level of cash crops is better than that of grain crops, tobacco leaves, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, tobacco, The geographic agglomeration of apple is relatively obvious, and the agglomeration pattern of agricultural geography has evolved from the internal pressure to form the natural agglomeration pattern. The geographical agglomeration of main crops in Sichuan Province is in the process of trial and error correction and has not yet formed a new round of regional distribution and division of labor of agricultural production.
