A comprehensive assessment of chemical quality of flue-cured tobacco from Fengqing county, Linxiang district, Yongde and Yun county of Lincang city in 2004 and 2005 was carried out based on set pair analysis (SPA) method. Fuzziness of grade boundary and determination of uncertainty coefficient and the SPA was compared with exponential sum method. Results showed that chemical quality of flue-cured tobacco from Lincang city was high generally, while that in Yongde county maintain stability at top grade, and the other three counties (or district), however, ranged from Grade I to Grade Ⅲ in different years. It was suggested that the level of cultivation techniques and managements need to be improved in the three counties (or district). SPA method was more reasonable, concise, and direct by comparison.%采用集对分析法,考虑了等级标准边界的模糊性,避免了直接确定联系度中的不确定系数,对临沧市凤庆县、临翔区、永德县和云县2004年和2005年烤烟烟叶化学品质进行了综合评价；并将集对分析法与指数和法进行了比较.结果表明:总体上临沧烤烟化学品质较好,永德县烟叶化学品质等级最高,为最好的Ⅰ级,且年际间稳定,而其余3县(区)烟叶化学品质等级为Ⅰ～Ⅲ级,年际间较不稳定,应注重栽培技术和管理水平的提高；集对分析方法的评价结果较指数和法更合理,而且评价结果简明、直观.
