| 及时掌握我国油料作物生产区域集中化演进趋势，对于优化油料作物生产布局、有效确保油料产品稳定供给和国家食用油安全等具有重要意义。基于1991—2022年省级尺度油料作物数据，运用空间洛伦兹曲线的集中化指数，从油料产业整体和品种细分视角对1991—2022年我国油料作物生产布局动态演进趋势展开定量研究。结果表明：从油料产业整体视角看，油料作物生产区域集中化水平呈现上升趋势，空间集聚趋势渐强；不同省份对油料产业生产布局动态演进的影响存在差异，河南省、湖北省、四川省、湖南省、山东省等省份对油料产业生产空间集聚起主导性作用。从品种细分视角看，花生生产集中化水平呈下降趋势，呈现“降—升—降—升—降”演化进程；油菜籽生产集中化水平呈上升趋势，呈现“波浪上升—平稳上升”演化进程；花生和油菜籽生产布局都出现了较大幅度的位置变化，前者生产逐渐向河南省、山东省、广东省、辽宁省等省份集中，后者生产逐渐向四川省、湖北省、湖南省等省份集中。建议稳定和丰富油料原材料供给及其来源，稳抓和优化花生和油菜籽等油料主产区产能和生产布局，保障我国油料产业安全和粮油安全。 |

| Timely understanding the evolution trend on concentration of oil-bearing crops production region in China, it is of significance to optimize the oil-bearing crops production layout and ensure the stabilization of oil-bearing crops products supply as well as national food security. Basing on the provincial date of oil-bearing crops production from 1991 to 2022 and using the concentration index of Lorenz curve, the dynamic evolution trend of oil-bearing crops production layout from the perspective of oil-bearing crops industry and variety was quantitatively analyzed. The results showed that from the perspective of oil-bearing crops industry,the centralization degree of oil-bearing crops production region showed an upward trend obviously from 1991 to 2022, and the trend of spatial agglomeration of oil-bearing crops production region strengthened. There were significant differences toward impact on the dynamic evolution of oil-bearing crops industry layout in different provinces, and Henan, Hubei, Sichuan, Hunan and Shandong played a leading role in spatial agglomeration of oil-bearing crops industry. From the perspective of variety, the concentration level of peanut production showed a downward trend, presenting a "falling-rising-falling-rising-falling" evolutionary process, the concentration level of rapeseed production showed a rising trend, presenting a "wave rising-smoothly rising" evolutionary process. Producing areas of peanut and rapeseed both showed a certain degree of location migration, peanut was gradually concentrated to Henan, Shandong, Guangdong and Liaoning, and rapeseed was gradually concentrated to Sichuan, Hubei and Hunan. It is recommended to stabilize and enrich the supply of oilseed raw materials and their sources, steadily grasp and optimize the production capacity and production layout of the main oilseed producing areas, such as peanut and rapeseed, so as to safeguard the security of China′s oil-bearing crops industry and the security of grain and oil. |
