摘要:

分析1988—2017年四川省油菜生产的时空演变特征,为进一步稳定四川油菜种植面积和优化油菜生产区域布局提供科学参考。对1988—2017年四川省油菜生产相关数据进行分析整理,利用区域重心分析法和比较优势指数法对区域布局和优势差异进行量化计算。结果表明,1988—2017年四川省油菜播种面积与总产量呈正相关的波动增长趋势,且油菜产量较油菜播种面积增长更快,油菜生产在区域间和区域内部分布不均。油菜播种面积和单产水平对油菜总产量有直接影响。1988—2017年四川省油菜生产重心基本稳定,油菜的主要生产区域由成都平原向川东北迁移,同时向川南地区扩展。结合分析结果,四川省应重视油菜生产布局规划,充分发挥各区域比较优势,加强基础设施建设投入,促进油菜种植规模化,积极引进农业科技人才,推广双低、高产、多抗、广适应的油菜新品种。

Abstract:

By analyzing the temporal and spatial changing of rapeseed production in Sichuan Province in 1988-2017, the paper aims to provide certain references for further stabilizing the planting area and optimizing the regional distribution. Based on the analysis and arrangement of rapeseed production data, the regional distribution and superiority differences were quantitatively calculated by using the method of regional gravity center analysis and the method of comparative advantage index. From 1988 to 2017, there was a positive correlation between the total yield and the planting area of rapeseed in Sichuan Province, and the rapeseed yield increased faster than the planting area, rapeseed production was unevenly distributed among and within regions. The total yield of rapeseed was directly affected by the planting area and the yield per unit area. The production center of rapeseed in Sichuan Province was basically stable from 1988 to 2017, and the main production area of rapeseed migrated from the Chengdu Plain to northeast Sichuan, and expanded to the south of Sichuan. Combining with the analysis results, Sichuan Province should pay attention to rapeseed production layout planning, take full advantage of regional comparative advantages, strengthen the investment of infrastructure construction, promote rapeseed cultivation on a large scale, actively introduce agricultural scientific and technological talents, and popularize the new rapeseed varieties with double-low, high yield, multi-resistance and wide adaptability.

Key words: Sichuan Province, rapeseed production, temporal and spatial changing, pattern feature, center of gravity
