Luzhou is a tobacco-growing area of Sichuan, the Gulin county and Xuyong county are the main tobacco-growing area in Luzhou. The production of Flue-cured tobacco promoted development of economic, and it contribute to the rural construction. So, to explore the characteristics of flue-cured tobacco in luzhou, it is the important step that improved the quality of flue-cured tobacco usability, and it is key to realize sustainable development of luzhou flue-cured tobacco.To explore the characteristics of high quality flue-cured tobacco in Luzhou, Using comprehensive empowerment method to calculate weight of the indexes, and analyzes the stability of flue-cured tobacco between annual indexes, to increase the use of the matter-element extension model for all kinds of indexes, the area location and produce smoke zone characteristics, using cluster analysis again locate regionalization result clustering.In addition, using the least square analysis of variance to explore luzhou flue-cured tobacco scent, lasting appeal, and the relationship between the various indicators. Finally, the results of this analysis in G1S graphic display can be intuitive analysis of various kinds of indexes in the graphic characteristic changes of continuity. Main conclusions are as follows:(1) Dividing the appearance characteristics of tobacco into five categories, according to prominent features to not prominent labeled " Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ" in Luzhou. The characteristic indexes of tobacco leaf in the appearance, color and oil content is "Ⅲ-Ⅱ ", maturity and chromaticity is "Ⅰ-1 ", as "Ⅱ", blade structure is " Ⅰ ". Tobacco leaf of appearance index between the annual change is in a stable state, the smoke zone Fenshui town overall appearance features prominently. Overall, inter-annual changes of appearance indexes is in a relatively stable state in Luzhou, leaf structure is loose, thickness is moderate.(2) Dividing the chemical characteristics of tobacco into five categories, according to prominent features to not prominent labeled "Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ" in Luzhou.The characteristic index of tobacco leaf in the chemical indexes, total sugar, nitrogen and alkali is "Ⅱ ", reducing sugar, chlorine is "Ⅲ-Ⅱ", potassium chloride ratio and starch is "Ⅳ-Ⅲ", total nitrogen, potassium is " Ⅰ ", total nicotine is "", sugar alkali is " Ⅱ-Ⅰ ". Overall, the tobacco leaf chemical indicators of total sugar, reducing sugar and total nicotine, sugar alkali, chlorine, total nitrogen, alkali nitrogen ratio, is stability. Potassium, potassium chloride, starch, is a little stability. Overall,total sugar, sugar, total nicotine, sugar/nicotine, chlorine, nitrogen, nitrogen/nicotine is stability. Potassium, potassium/chlorine, potassium is a little stability. Nitrogen, potassium is coordinated. Total sugar, sugar/nicotine, nitrogen/nicotine is not coordinated.(3) Dividing the sensory characteristics of tobacco into five categories, according to prominent features to not prominent labeled " Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ" in Luzhou.The characteristic index of tobacco leaf in the sensory indexes, the temperament, clouds, excitant is " Ⅱ", aftertaste, back to the sweet feeling is " Ⅱ-1 ", the aroma quantity is "Ⅲ-Ⅱ", miscellaneous gas is " Ⅰ ", dry is " Ⅰ", smooth is " Ⅰ ". Overall, tobacco sensory index change is a bit stable, sweet temperament, aftertaste, mixed gas, irritating, back to the sweet feeling, dry feeling, fine degree and conglobation indicators features prominently, other indicators characteristic is not obvious. Shuangsha town, Guanwen town smoke zone sensory characteristics is more prominent. Overall, sensory index is a little stability, aroma, aftertaste, miscellaneous gas, irritation, sweetness, dryness, exquisite is featured.(4) The scent type is the middle scent. The lasting appeal is Sweet like nuances, hay like nuances, sweet hay like nuances.(5) In central guizhou, wuling mountain area, qinba mountains, shandong mountain, northeast mountain area of total sugar, reducing sugar and total nicotine, chloride, potassium chloride ratio, total nitrogen, nitrogen alkali than content is better than that of luzhou flue-cured tobacco zone. And sugar/alkali, potassium, nitrogen, alkali content,luzhou flue-cured tobacco zone zone is dominant.
