为了进一步评价气候条件对云南黄金走廊烟区烤烟生产的影响,通过对云南黄金走廊烟区10个州53个县1971-2004年共34年的光照、温度、降雨量等主要气象因子数据进行分析,以烤烟生育期均温、生育期最高气温、生育期最低气温、生育期累积日照时数、生育期降水量、生育期蒸发量、生育期平均相对湿度等为指标,基于 SPSS系统聚类方法将云南黄金走廊烟区划分为4个气候类型区域,并分析了各类型的气候特点,结果表明生育期均温、最高温、累计日照和平均相对湿度在4个气候类型区之间差别较小,而生育期最低温、降雨量和蒸发量在4个气候类型区之间具有明显差异,可能是影响黄金走廊烟区特色烤烟品质的关键。
In order to further evaluate the effect of climate conditions of Yunnan Golden Corridor on tobacco production, meteorological factors data such as sun-shine, temperature and rainfal over 34 years (1971-2004) in 53 counties of 10 pre-fectures across Yunnan Golden Corridor were analyzed. Based on the SPSS sys-tematic clustering method, with the growth stage average temperature, highest tem-perature, lowest temperature, total sunshine duration, rainfal , evaporation and aver-age relative humidity being the indexes, Yunnan Golden Corridor Tobacco Area could be divided into places with four climate types. The characteristics of four cli-mate types were also analyzed, which indicates that the differences of growth stage average temperature, highest temperature, total sunshine duration, and average rela-tive humidity among four climate types were relatively smal , while there existed sig-nificant differences between growth stage lowest temperature, rainfal and evapora-tion of four climate types, which might be the key factors that influence the special quality of tobacco from Golden Corridor.
