摘　　要：利用贵州乌蒙烟区1961-2000年的气温、日照时数、降雨量等主要气候因子数据,分析了烤烟生育期气候指标的变化特点,结果表明：乌蒙烟区光照充足、降雨丰富、气温相对偏低,但气温年际间相对稳定,光照和降雨量在不同年份间存在较大波动。线性趋势分析表明：旺长期（6月）气温呈现较显著的上升趋势,成熟初期（7月）气温显著下降;烤烟生育期每月日照时数呈减少趋势,其中成熟初期（7月）的日照时数减少趋势显著;降雨量在5月、6月呈减少趋势,7月、8月呈增加趋势,生育期每月降雨量的线性变化趋势未达到显著水平。突变检验表明：40年来该烟区烤烟生育期气温在1998年发生了明显突变,日照时数在1985年发生了明显突变,降雨量未发生明显突变。Using the major meteorological data in term of temperature,sunshine duration and rainfall during 1961 - 2000 in Wumeng tobacco- growing area of Guizhou province,the author analyzed the characteristics of climatic factors changes at flue-cured tobacco growth stage. The results indicated that Wumeng tobacco- growing area was provided with adequate sunshine duration and rainfall,but its average air temperature was relatively low. The air temperature was relatively stable among different years,while the sunshine duration and rainfall fluctuated largely among different years. Linear trend analysis showed that the air temperature at tobacco vigorous growth stage（ June） had a significant upward trend,but that at tobacco initial maturing stage（ July） dropped significantly. In growth and developmental period of flue- cured tobacco,the monthly sunshine duration showed a decreasing trend,and this trend was obvious in July; the rainfall revealed a declining trend in May and June,and showed an increasing trend in July and August,but the linear variation trend of monthly rainfall was not significant. Mutation analysis showed that： in the past 40 years,during the growth and development of flue- cured tobacco in this area,the air temperature and sunshine duration appeared an obvious mutation in the year 1998 and 1985,respectively,while the rainfall did not appear marked mutation.
