摘　　要：为明确典型浓香型产区烟草生育期光照、温度、降水等气候因子的历史演变规律,采集了典型浓香型产区的重点浓香型产烟县1981—2011年31年中以候为基础的气候资料,并对产区烟草大田生长期气候指标的变化趋势进行了分析。结果表明,豫中豫南典型浓香型烟区烟草伸根期和旺长期的平均气温、有效积温、昼夜温差及光照时数显著大于南方典型浓香型烟区(皖南、湘南粤北赣南),降雨量及相对湿度显著小于南方烟区,但烟叶成熟期时各烟区的气候条件差异不显著。从年际变化规律来看,各产区烟草伸根期和旺长期的降雨量及相对湿度呈波动下降趋势,平均气温、有效积温和昼夜温差均呈波动上升趋势。烟叶成熟期,南方典型浓香型烟区降雨量呈下降趋势,平均气温、有效积温和昼夜温差呈波动上升趋势;北方典型浓香型烟区的降雨量呈上升趋势,平均气温、有效积温和昼夜温差相对较为稳定。To analyze the historical evolution of the climate factors（such as light, temperature, precipitation and so on） during tobacco growing periods in typical robust flavor style tobacco areas, 31 years of climatic data（1981—2011） based on five-days interval were collected in typical robust flavor style tobacco growing counties,and analyzed the change tendencies of climate factors.The results showed that the average temperature,effective accumulated temperature, diurnal temperature and sunshine hour of the central and south Henan tobacco-planting areas in the root elongation and vigorous growth stages were significantly more than that of typical robust flavor style tobacco-planting areas in south China（south Anhui and south Hunan, north Guangdong and south Jiangxi）, and the precipitation and relative humidity were significantly less than that of typical robust flavor style tobacco-planting areas in south China.However, the climate differences during the maturation stage in two tobacco-planting areas were not obvious.On the annual variation, the precipitation and relative humidity of each tobacco-planting area decreased with fluctuating during the root elongation and vigorous growth stages, in contrast with the average temperature, effective accumulated temperature and diurnal temperature.In the maturation stage, the precipitation decreased and the average temperature, effective accumulated temperature and diurnal temperature increased with fluctuating in typical robust flavor style tobacco-planting areas in south China.The precipitation increased and the average temperature, effective accumulated temperature and diurnal temperature were relatively stable in typical robust flavor style tobacco-planting areas in north China.
