Abstract: In order to evaluate the feasibility of biomass energy curing and improve the evaluating system of the appearance quality of flue-cured tobacco,tobacco leaves samples from biomass energy curing areas in Yunnan were used as materials to construct an evaluation system for the appearance quality of biomass energy cured tobacco by utilizing expert consultation,descriptive statistics,variance analysis,cluster analysis and geo-statistical analysis,and the correlation of the indexes of the evaluation system of appearance quality and regional characteristics of appearance quality of flue-cured tobacco with biomass energy in Yunnan were analyzed.The results indicated that there was a very significantly positive correlation among maturity,growth status,leaf structure,body,oil,chroma,chromatic homogeneity,smooth or green-yellow of the evaluation indexes of appearance quality of biomass energy flue-cured tobacco in Yunnan.Its maturity was closely related to other indexes,while leaf structure had little influence on other indexes.The scores of appearance quality of different grades of tobacco leaves were X2F<B2F<C3F,the difference was very significant,and the scores of appearance quality of different varieties of tobacco leaves were Yunyan 87<K326<Hongda.The high value of tobacco appearance quality index appeared in tobacco planting areas of the central Yunnan,and gradually decreased in the surrounding areas,with obvious spatial trend.The tobacco planting areas with high tobacco appearance quality index mainly concentrated in Chuxiong,Kunming and Yuxi.The quantitative evaluation system of appearance quality of biomass energy flue-cured tobacco is relatively reasonable,and it is feasible to evaluate comprehensively the appearance quality of biomass energy cured tobacco in Yunnan.

摘要： 为评判生物质能源烘烤的可行性以及完善烟叶外观质量评价体系，以云南省生物质能源烘烤产区烟叶样品为材料，运用专家咨询法、描述性统计法、方差分析法、聚类分析法和地统计学分析法，构建了生物质能源烘烤烟叶的外观质量评价体系，并分析了外观质量评价体系指标间的关系和云南省生物质能源烘烤烟叶外观质量的区域特征。结果表明，云南省生物质能源烘烤烟叶外观质量评价指标成熟度、发育状况、叶片结构、身份、油分、色度、色均匀度、光滑或微青间存在极显著正相关关系，其中成熟度与其他指标关系密切，而叶片结构对其他指标的影响较小；不同等级烟叶的外观质量分值表现为X2F＜B2F＜C3F，差异极显著；不同品种烟叶的外观质量分值表现为云烟87＜K326＜红大；烟叶外观质量指数高值区域出现在滇中烟区，向四周逐渐递减，空间变化趋势明显；烟叶外观质量指数高的烟区主要集中在楚雄州、昆明市、玉溪市。可见，构建的生物质能源烘烤烟叶外观质量量化评价体系较为合理，对云南省生物质能源烘烤区域烟叶外观质量进行综合评价是可行的。
