Caption

Linear regression of soil organic carbon (SOC) content and extracellular enzyme activities in the alpine meadow and the swamp meadow. (A) SOC vs BG; (B) SOC vs PER; (C) SOC vs PER and; (D) SOC vs oxidase/hydrolase. The line(s) in each panel represent the linear regression line with p <0.05, and the shaded area indicates the 95% confidence interval. The numbers in the figure show the significance (P) and correlation coefficient (R2) of the linear fitting results. Oxidase/hydrolase refers to the ratios of oxidase to hydrolase activities, calculated as ((PER+POX)/2)/BG.
