Based on the SPSS sys- tematic clustering method, with the growth stage average temperature, highest tem- perature, lowest temperature, total sunshine duration, rainfall, 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 small, while there existed sig- nificant differences between growth stage lowest temperature, rainfall and evapora- tion of four climate types, which might be the key factors that influence the special quality of tobacco from Golden Corridor.展开更多
