Abstract: The research aims to make clear the characteristics of spatial distribution of tobacco soil pH value and soil nutrient in Guangyuan, the correlation between soil nutrients and pH value, thus to provide scientific basis for reasonable fertilization in tobacco planting of Guangyuan. The content of 846 soil samples in Guangyuan tobacco area were collected, detected and analyzed from 2013 to 2014. The results showed that an average of soil pH was 7.68±0.7 in Guangyuan tobacco area, the variation coefficient was 9.06%, samples with pH between 7.5 and 8.5 accounted for 69.53% of the total. The coefficient variation of available P, Fe, Zn, B and exchangeable calcium were 50%-100%, close to strong variability; the coefficient variation of available Cu and S were greater than 100%, and the coefficient variation of available S was the maximum, its value was 107.12%; the coefficient variation of available Mn was the minimum, its value was 22.51%. The soil pH and available S, exchangeable calcium and exchangeable magnesium were positively correlated, the correlation coefficient was 0.31^*, 0.51^* and 0.14^*, respectively. Therefore, the Guangyuan tobacco soil nutrient content was unbalanced, the soil pH was overall alkali, soil organic matter and available B were lack, alkali hydrolyzable N and available K content were low, available P and Zn were moderate; Mn, Fe, Cu, S and exchangeable magnesium ion were abundant, exchangeable calcium ion were overall very rich.
