Abstract: In order to establish the GAP system in tobacco production and conduct tobacco leaf quality assessmentU1 in Shaoyang, environmental factors such as surface water, air and soil in Shaoyang flue-cured tobacco planting regions were investigated and analyzed, and environmental factors and flue-cured tobacco leaf quality under GAP system were assessed. The results showed that the met the criterion of the primary standard of GB3095-2012, the surface water quality met the level 3 standard of GB3838-2002, and the quality of most tobacco planting soils met the second level of GB15618-1995. Air, surface water and soil quality all met the requirements of high-quality flue-cured tobacco production. After application of the GAP system in 2013, the coordination of main chemical component indicators of tobacco leaves, evaluation of appearance characteristics of raw flue-cured tobacco and smoking quality indicators of X2F, C3F and B2F in 2013 were all improved in comparison with 2012. Quality assurance of tobacco production requires suitable varieties, an effective system of environmental monitoring, a rational flue-cured tobacco planting base, and a GAP-based production technology system.
