2.7 Statistical analysis
The significant differences between the mean under different land covers
were tested using analysis of variance (ANOVA) and compared by Tukey
post hoc test at α ≤ 0.05 significance level. The statistical
relationship between different parameters and factors influencing them
was assessed using Pearson correlation analysis. Regression analysis was
carried out to investigate the relationship between the dependent
variable (N-mineralization) with independent variables (TN and C:N
ratio). All statistical analyses in this study were performed using
SPSS21.0
