Effects of Plant Community Type on Soil Methane Flux in Semiarid Loess Hilly Region,Central Gansu Province,China
文献摘要：
Methane(CH4)is an important greenhouse gas second only to CO2 in terms of its greenhouse effect.Vegetation plays an important role in controlling soil CH4 fluxes,but the spatial variability of soil CH4 fluxes during vegetation restoration in Loess Hilly Region(LHR)is not fully understood.The effects of different plant community types[Medicago sativa grassland(MS);Xanthoceras sorbifolium forestland(XS);Caragana korshinskii bushland(CK);Hippophae rhamnoides shrubland(HR);and Stipa bungeana grassland(SB)]on soil CH4 flux in LHR were studied via the static chamber technique.The results showed that the five plant community types were sinks of soil CH4 in LHR,the plant community type significantly affected the soil CH4 flux,and the average CH4 uptake from high to low was in SB,HR,CK,MS,and XS.During the whole study period,the soil CH4 flux showed similar interannual variation.The maximum absorption of soil CH4 appeared in the growing season,while the minimum appeared in winter.Soil CH4 uptake was positively correlated with soil temperature and soil moisture.Soil temperature and moisture are important controlling factors for the temporal variability of soil CH4 flux.In LHR,the Stipa bungeana grassland is the more suitable plant community type for reducing soil CH4 emissions.In the process of vegetation restoration in LHR,the soil CH4 absorption potential of different plant community types should be considered,ecological benefits should be taken into account,and vegetation more suitable for mitigating the greenhouse effect should be selected.
