干旱区农业由于独特的资源环境约束，在区域社会经济、生态文明建设过程中具有重要的作用。以新疆为例，在县域尺度运用重心迁移模型、区位基尼系数、比较优势指数、全局莫兰指数等方法，探析2000—2020年新疆6类主要农作物生产时空格局演变特征与影响因素。结果表明：（1） 2000—2020年新疆农业种植规模不断扩大，主要农作物生产之间形成了棉蔬果“进”、粮油糖“退”的基本竞争态势。（2） 6类主要农作物的生产重心聚集于区域内中西部，且棉花、蔬菜、瓜果生产集聚程度不断增强，生产规模向少数县域聚集。（3） 在全国层面新疆主要农作物生产均具有效率比较优势，棉花、糖料、瓜果生产兼具规模比较优势和综合比较优势，尤其是棉花生产的规模比较优势十分显著。在本地区层面新疆多数县域主要农作物生产不具有比较优势，且部分具有比较优势的县域也主要以规模主导优势为主。（4） 政策引导、技术进步及农民收入的增加是影响区域主要农作物生产格局演变的重要因素。

Agriculture in arid regions plays a vital role in advancing local socio-economic development and ecological sustainability, given the unique resource and environmental constraints. This study examines Xinjiang, China, as a case study, utilizing the center of gravity transfer model, locational Gini coefficient, comparative advantage index, and global Moran’s I index at the county level to analyze the spatio-temporal evolution and influencing factors of the six major crops from 2000 to 2020. The results indicate that: (1) Xinjiang’s agricultural planting scale has been growing steadily from 2000 and 2020, and cotton, vegetables, and melons “advancing”, grain, oil, and sugar crops “restreating” constitute the basic competitive situation of the major crops. (2) The production centers for the six major crops are predominantly located in the central and western regions of Xinjiang. The concentration of cotton, vegetables, and melon production has steadily increased, with production becoming concentrated in a relatively small number of counties. (3) At the national level, all six major crops exhibit efficiency comparative advantages. Cotton, sugar, and melon production demonstrate both scale and comprehensive comparative advantages, with cotton showing a particularly pronounced scale advantage. At the regional level, most counties in Xinjiang lack comparative advantages in crop production. Counties with comparative advantages are primarily scale-dominated. (4) The evolution of Xinjiang’s crop production pattern has been influenced by several critical factors, including policy directives, technological advancements, and rising farmer incomes.
