摘　　要：【目的】揭示与龙山县典型山地烤烟风格紧密相关的气象因子。【方法】以龙山县30年(1986—2015年)连续气象资料为基础,采用非线性多项式拟合回归方法分析了龙山烤烟大田不同生育期的气候变化特征。【结论】(1)龙山县烤烟伸根期日气温平均值为20.54℃,日照时间平均值为3.83 h,日降水量平均值为10.41 mm,空气湿度适中。但日均温和日照时间波动较大。(2)旺长期日气温平均值为24.52℃,日照时间平均值为4.39 h,日降水量平均值为12.14 mm,相对湿度先增后降,波动较大。(3)成熟期相对湿度适中,平均值为77.77%,气温和日照时间前期较高,后期下降较快。【结论】龙山烟区烤烟大田生育期光、温、水同步增加,气温和相对湿度适宜,降水丰富,日照时间前寡后足。龙山独特的气象条件为典型山地特色烟叶的形成提供了保障。[Purpose]To reveal the ecological factors closely related with the style features of the typical mountain type flue-cured tobacco in Longshan County.[Method]Based on the meteorological data from 1986 to 2015,we analyzed the climate change characteristics of flue-cured tobacco field growth period of Longshan Country by a nonlinear polynomial regression method.[Results](1)The average daily temperature,sunshine time and rainfall of the root spreading stage of flue-cured tobacco in Longshan County were 20.54℃,3.83 h,10.41 mm,respectively,and air humidity was also suitable for the growth of flue-cured tobacco.However,the average daily temperature and sunshine time fluctuated greatly.(2)At the rapid growth stage of flue-cured tobacco in Longshan County,the average daily temperature,sunshine time and rainfall were 24.52℃,4.39 h and 12.14 mm,respectively.Relative humidity increased at first and then decreased,and fluctuated greatly.(3)At the maturing stage air humidity is moderate,the value of which was 77.77%.The average daily temperature and sunshine time were higher in early stage and then decreased rapidly in later period.[Conclusion]The average sunshine time,daily temperature and rainfall in field growth stages of flue cured tobacco increased synchronously in Longshan tobacco growing area.The daily temperature and air humidity were suitable.Rainfall was abundant,and sunshine time was less in the early stage and abundant at the later stage.The unique meteorological conditions of Longshan provide a guarantee for the formation of typical mountain characteristic tobacco leaves.
