AFDM: ash-free dry mass; SM: sediment moisture; TOC: total organic carbon; TN: total nitrogen; TP: total phosphorus; C : N means the ratio of total organic carbon to nitrogen. All the data was shown in the mean ± SD format. The significantly different values among sites were marked with different letters (ANOVA based on Tukey test, < 0.05).
