| 摘 要： | 胡麻是我国重要的纤维和油料作物之一。基于1985-2015年的全国县域胡麻子生产数据,分析了我国胡麻种植面积、胡麻子产量和单产的时空动态变化特征,揭示了胡麻子生产的重心迁移轨迹和贡献率变化,同时评估了全国胡麻子生产优势度。结果发现,1985-2015年,胡麻子生产中20%的面积与产量集中于阴山以南地区、六盘山以东地区;我国胡麻种植面积、胡麻子产量重心分别向东南方向迁移了193和303km;我国胡麻子生产主导因素主要为面积,约占所有主导型之和的40%;我国胡麻子生产规模、生产效率以及综合优势区域均位于甘肃省。结果表明,全国胡麻种植规模趋于稳定、胡麻子单产不断上升以及胡麻子生产重心向南转移是我国胡麻子生产变化的主要特征,这主要受到政策鼓励、品种创新等的影响。

| Abstract: | Flax is one of the most important fiber and oil crops in China. This research was conducted to figure out the spatio-temporal dynamic changes of national planting area, production and unit yield in linseed based on the county data from 1985 to 2015. Furthermore, this article revealed the migration track of production center of linseed and the changes in contribution rate. And on the basis, we assessed the superiority of linseed production in different areas of China. The result showed that the 20% of linseed planting area and production were concentrated in the south of Yinshan and east of Liupanshan from 1985 to 2015, and the foci of planting area and production migrated to southeast for about 193km and 303km, respectively. Among all the influence factors for linseed production, the dominant one was planting area, which accounted for about 40%. Gansu Province had been a leading position in production scale, productive efficiency and comprehensive advantages in linseed. In conclusion, under influence of policy support and variety innovation, the national linseed production becomes stable, unit yield is rising and the focus of linseed cultivation shifts towards south. |
