Abstract: In order to scientifically plan the tobacco cultivation in Qujing, Yunnan Province, we analyzed 13 chemical indices of tobacco from 9 counties of Qujing by using the gray correlation decision model, which is based on variation coefficient method. According to the chemical composition analysis, the tobacco quality from the 9 counties could be sorted as follows: Xuanwei> Fuyuan> Huize> Luoping> Qilin> Shizong> Zhanyi> Malong> Luliang. The results showed that tobacco of Xuanwei had the optimal quality, while those from Luliang had the worst quality.
