摘　　要：【目的】为兴山烟区不同海拔高度烤烟移栽期的确定和气候资源最大化利用提供科学依据。【方法】分析了湖北兴山烟区不同海拔高度、不同移栽期的气候状况,估算了该区气候适生性指数(CFI),并与国外优质烟区进行了气候相似性分析。【结果】(1)在统一移栽期(05-10)下,兴山不同海拔的CFI值表现出低海拔最高、高海拔最低、中海拔居中的特点;不同海拔气候条件与国外烟区的相似程度以巴西最高,津巴布韦次之,美国最低。(2)不同移栽期下,兴山烟区的CFI值均表现为低海拔>中海拔>高海拔;不同海拔气候条件与国外烟区的相似程度表现为巴西>津巴布韦>美国。【结论】兴山烟区低、中、高海拔烟区烤烟的适宜移栽期分别为4月下旬、5月中旬和5月下旬。[Objective] The analysis could be used as a reference to determine transplanting dates at different altitudes and make full use of the natural resources of Xingshan. [Method] The climate conditions at different altitudes and different transplanting dates of Xingshan tobacco-growing areas were analyzed, the climate feasibility indexes （CFI） were estimated, and similarity analysis of climate conditions between Xingshan tobacco-growing areas and high-quality tobacco-growing areas overseas was also conducted. [Result] （1） On the same transplanting day （May 10） ,CFI values at different altitudes showed that it was the biggest at the altitude of 〈 800 m,the lowest at the altitude of 〉1 200 m,and medium at the altitude of 800-1 200 m. The similarity of the climate conditions at different altitudes between Xingshan tobacco-growing areas and high-quality tobacco-growing areas overseas showed the trend of Brazil 〉 Zimbabwe〉America. At different transplanting dates,CFI values at different altitudes showed that low altitude 〉 medium altitude 〉 high altitude; the similarity of the climate conditions at different altitudes of Xingshan with tobacco-growing areas overseas showed Brazil 〉 Zimbabwe 〉America. [Conclusion] The transplanting dates of Xingshan tobacco-growing areas at different altitudes were proposed. It was suggested that low altitude was fit for transplanting in the last ten days of April,medium altitude was fit for transplanting in the second ten days of May,and high altitude was fit for transplanting in the last ten days of May.
