[目的]小麦是我国主要粮食作物之一,研究小麦空间布局演变规律和驱动因素,是进一步优化小麦生产布局,提高小麦综合生产能力,保障国家粮食安全的现实要求。[方法]通过文献综述方法,比较全面地介绍了集中度指数、比较优势指数、变异系数和空间统计分析、农业生态区AEZ模型、重心模型、耕作制度区划、Moran′s I及 Panel Data 模型等在小麦生产布局和驱动因素研究中的应用。[结果]在全面讨论上述方法应用于小麦空间布局演变研究的适用性后,总结归纳了推动我国小麦空间布局演变的主要驱动因素。[结论]我国粮食空间布局演变的总体规律为:由“南粮北调”转变为“北粮南运”、“北进中移”,北部和中部成为了全国粮食的增长中心。我国小麦空间布局演变的驱动因素主要有气候因素、技术进步因素、生产投入因素和其他社会因素。 |

Abstract: |
The paper made a comprehensive review on the theories and methods of crop production and spatial distribution. Special attention was given to the changes of distribution and driving forces of wheat production in China. In the paper, concentration index, comparative advantage, variation index, spatial statistics, AEZ model, gravity model, cropping zoning, Moran′s I, panel data analysis, and etc., which were used to analyze wheat production and its spatial distribution, were discussed and compared. The driving forces of wheat production and its spatial distribution have been identified. Based on the review, it was found that the spatial distribution of China′s cereal grain production has been changing and shifted from Southern to Northern. North and Central China are nowadays′ core regions of cereal grain production. The information and summaries of this paper is informative and helpful for further studies. |
