| 英文摘要 | Litter decomposition is the key process in nutrient recycling and energy flow. the present study examined the impacts of soil fauna on decomposition rates and nutrient fluxes at three succession stages of wetland in the sanjiang plain, china using different mesh litterbags. the results show that in each succession stage of wetland, soil fauna can obviously increase litter decomposition rates. the average contribution of whole soil fauna to litter mass loss was 35.35%. the more complex the soil fauna group, the more significant the role of soil fauna. the average loss of three types of litter in the 4mm mesh litterbags was 0.3-4.1 times that in 0.058mm ones. the decomposition function of soil fauna to litter mass changed with the wetland succession. the average contribution of soil fauna to litter loss firstly decreased from 34.96% (carex lasiocapa) to 32.94% (carex meyeriana), then increased to 38.16% (calamagrostics angustifolia). the contributions of soil fauna to litter decomposition rates vary according to the litter substrata, soil fauna communities and seasons. significant effects were respectively found in august and july on c. angustifolia and c. lasiocapa, while in june and august on c. meyeriana. total carbon (tc), total nitrogen (tn) and total phosphorus (tp) contents and the c/n and c/p ratios of decaying litter can be influenced by soil fauna. at different wetland succession stages, the effects of soil fauna on nutrient elements also differ greatly, which shows the significant difference of influencing element types and degrees. soil fauna communities strongly influenced the tc and tp concentrations of c. meyeriana litter, and tp content of c. lasiocapa. our results indicate that soil fauna have important effects on litter decomposition and this influence will vary with the wetland succession and seasonal variation. |
