摘　　要：分析了2001-2008年许昌气候因素的变化情况，估算了该区不同移栽期的气候适生性指数，并与国外优质烟区气候进行了相似性分析．研究结果表明，2001—2008年烤烟大田生长期温度呈升高趋势，生育前期4—5月降水量有所减少，降水较集中的6—7月降水量有所增加，整个生育期日照时数明显减少，湿度较适宜．许昌烟区在04-15至05—05移栽，气候适生性指数相对较高，变化范围为0．841～0．856．许昌烟区与国外优质烟区（津巴布韦、巴西、美国）的相似度均较高，与巴西和津巴布韦的相似距离均以04-15至04—30移栽相对较小．鉴于蚜虫迁飞高峰期，建议适时晚栽，最迟05—15前移栽完较为适宜．The changes of climatic factors were analyzed, and the climate feasibility indexes （CFI） were estimated for Xuchang from 2001 to 2008. The comparability analysis of climate conditions under different transplanting dates between Xuchang and tobacco-growing areas overseas was conducted. The results indicated that, the mean temperature from 2001 to 2008 increased during the field growing periods; the rainfall from April to May declined and the rainfall from June to July increased. The hours of sunshine were obviously reduced and the relative humidity was appropriate during the field growing periods. When flue-cured tobacco was transplanted from April 15 to May 5, the climate feasibility indexes （CFI） changed from 0. 841 to 0.856, which were relatively high. The comparability analysis of climate conditions under different transplanting dates between Xuchang and tobacco-growing areas overseas showed high similarity. The euclidean distance from April 15 to April 30 was relatively small for Zimbabwe and Brazil. Considering migration of aphids, the date before May 15 could be better for transplanting.
