Abstract: In order to compare the differences in economic characters of flue-cured tobacco between different growing areas in Henan Province, this paper used grey correlation clustering and decision methods to conduct comprehensive evaluation on following 3 targets: tobacco yield, first class, and middle class tobacco leaf proportion in 10 tobacco planting areas of Henan Province. The results indicated that according to the different economic traits of tobacco planted in different areas, the 10 tobacco planting areas could be divided into 4 categories: the first group included Sanmenxia, Luoyang and Jiyuan; the second group included Xinyang; and the third group included Xuchang, Nanyang, Zhumadian, Pingdingshan, Luohe; and the fourth group included Shangqiu tobacco planting areas. The comprehensive performance of tobacco economic traits of various flue-cured groups showed that the performance of Xuchang, Nanyang, Zhumadian, Pingdingshan, Luohe tobacco planting areas was the best, their comprehensive evaluation value was 0.98; followed by Sanmenxia, Luoyang and Jiyuan, their comprehensive evaluation value was 0.93; the performance of Xinyang tobacco planting areas was relatively low and their comprehensive evaluation value was 0.89; Shangqiu tobacco planting areas was the lowest and their comprehensive evaluation value was 0.85.
