| 为摸清新疆棉花生产变化与增产格局，本研究基于1988—2020年新疆棉花生产相关数据，运用数理统计和重心模型等方法对新疆棉花生产时空格局进行了分析，探讨了棉花增产格局与贡献因素。结果表明：1988年以来新疆棉花生产变化呈现两个阶段：波动增长时期（1988—2014年），棉花产量由17.12万t增至337.85万t，种植面积由22.13万hm2增至196.99万hm2；波动下降时期（2015—2020年），棉花产量波动降至302.70万t，种植面积减至163.67万hm2。1988—2020年，新疆大部分地市棉花产量、种植面积和单产显著增加，但各地差异明显，南疆在新疆棉花生产中地位突出，阿克苏、喀什和巴音郭楞3地对新疆棉花增产贡献为65.43%。北疆和东疆哈密棉花产量增幅快于南疆地区，致使棉花生产重心向东北方向迁移300.69 km，由喀什迁移至阿克苏境内。从贡献因素看，新疆棉花增产主要为种植面积主导（74.61%），未来新疆应将提高棉花单产作为保障棉花产量的主要途径。 |

| To understand the changes in cotton production and the pattern of yield increase in Xinjiang, mathematical statistics and gravity model were used to analyze the spatial and temporal pattern of cotton production in Xinjiang, and the pattern and contribution factors of cotton yield increase were discussed based on relevant data of cotton production in Xinjiang from 1988 to 2020. The results showed that the variation of cotton production in Xinjiang since 1988 showed two stages: fluctuating upward period (1988—2014), where cotton yield increased from 17.12×104 t to 337.85×104 t, and planted area increased from 22.13×104 hm2 to 196.99×104 hm2. During the period of fluctuating decline (2015—2020), the cotton yield decreased to 302.70×104 t, and the planted area decreased to 163.67×104 hm2. From 1988 to 2020, cotton production, planted area, and yield in most cities and regions of Xinjiang had significantly increased, but there were significant differences among different regions. Southern Xinjiang had a prominent position in cotton production in Xinjiang, with Aksu, Kashgar, and Bayingolin contributing 65.43% to the increase of cotton yield in Xinjiang. The increase rate of cotton production of Hami in eastern and northern Xinjiang was faster than that in southern Xinjiang, caused in the relocation of the cotton production center to the northeast by 300.69 km, from Kashgar to Aksu. From the perspective of contribution factors, the increase in cotton production in Xinjiang was mainly led by the planted area (74.61%). In the future, Xinjiang should consider increasing cotton yield per unit area as the main way to ensure cotton yield. |
