摘　　要：本文收集1991-2020年川西北地区32个国家级常规地面观测站气象观测数据,在分析川西北地区玉米种植区域的气候资源变化趋势的基础上,结合不同熟期玉米最适种植气候参数,利用反距离权重法和层次分析法对该地区的早、中、晚熟玉米种植进行农业气候区划。通过层次分析法对4种区划因子赋值并计算得到权重向量分别为0.56、0.26、0.12、0.06,根据权重向量计算川西北地区不同熟期的玉米种植气候区划数值。泸定区划数值最高,为3039.4;石渠区划数值最低,为145.4,表明泸定一线最适宜玉米种植,石渠一线最不适宜玉米种植。川西北适宜不同熟期的玉米种植区域主要集中在川西北地区的东部、东南部及中部部分区域。The meteorological observation data were collected from 32 national conventional ground observation stations in northwestern Sichuan from 1991 to 2020.Based on the analysis of the changing trends of climate resources in the maize planting area of northwestern Sichuan,and considering the optimal planting climate parameters of different ripe maize,the agricultural climate regionalization of early,medium and late ripe maize planting in this area was carried out by using the inverse distance weighting method and analytic hierarchy process.The four regionalization factors were assigned and calculated through the analytic hierarchy process and weight vectors were taken as 0.56,0.26,0.12 and 0.06,respectively.According to weight vectors,the climate regionalization of the maize planting with different maturity in Northwestern Sichuan were calculated.The Luding regionalization value was the highest at 3039.4,and the Shiqu regionalization value was the lowest at 145.4,indicating that the Luding line is the most suitable for maize planting,while the Shiqu line is the least suitable for maize planting.The suitable maize planting areas of different ripeness in Northwest Sichuan are mainly concentrated in the east,southeast,and central parts of the region.
