In order to improve the quality of tobacco leaf production and show the characteristics of flue-cured tobacco，the research comprehensively evaluates tobacco soil nutrient in Shidian areas and provide the theoretical basis of the soil aspects. Fuzzy math and multivariate statistical analysis are adopted to calculate the soil nutrient expressed by value of IFI，and statistical methods and GIS technology are applied to analyze their trend and spatiality. Studies indicated that the content of organic matter and alkali-hydrolyzable nitrogen of the soil in Shidian were slightly higher. And the quantity of the available P，available K，available Zn，available B were suitable while water soluble Cl was comparatively lower. The nutrient contents of the soil in Shidian varied widely and the coefficient of variation of various nutrient standards were 11%-76%. According to IFI，the tobacco-growing area was classified as 5 levels such as high，less higher，middle，less lower and low and the ratio of the three levels，less higher，middle and less lower accounted for 86.7%.Comprehensive evaluation shows that in tobacco soil nutrient the north-south areas is higher(the north is higher than the south )and the middle is lower in North-South direction；from west to east it gradually decreased in east-west direction. uneven nature of the topography in tobacco-growing areas led to the differences in soil nutrient，however，by using the evaluation flue-cured tobacco varieties and precision fertilizer，the actual production capacity in tobacco-growing areas will be increased．
