| 摘 要： | 为了研究我国粮食生产的优势区域分布，以我国县域为研究单元，运用综合比较优势指数法对全国分县粮食生产数据进行处理及分析，得到不同县域的SAd、EAI及AAI，然后采用ArcGIS克里金空间插值法对3种比较优势指数进行空间插值，确定我国粮食生产的优势区域。结果表明：我国粮食生产优势区域主要包括东北、黄淮海、江淮、湘赣、内蒙古中部、陕西中部、四川中东部及新疆西部8个地区，其中东北、黄淮海以及江淮是最具优势的地区，虽然总播面积仅占全国的50．59％，但粮食总产却占到63．88％。

| Abstract: | In order to study the advantaged region of the grain production in China, this paper processes and analyzes grain production data at county level by using eomprehsnive comparative advantage index method, and gets the SAI, EAI and AAI of different counties in China, then determines the dominant area of Chinese grain production with the AreGIS Kriging method. The results show that advantaged region includes the northeast area, Huang-Huai-Hai region, Jiang-Huai region, Hunan and Jiangxi Province, middle parts in Inner Mongolia, middle-Shanxi, central and eastern parts of Sichuan Province, western Xinjiang region. In addition, the northeast area and Huang-Huai-Hai and Jiang-Huai region are the most advantaged areas, although its total sowing area only accounted for 50.59% of China, the total grain output has accounted for 63.88%. |
