综述了不同经营措施对森林土壤碳库和温室气体排放的影响.大多数研究认为施肥可以显著增加土壤有机碳库,但同时也增加了土壤温室气体的排放;去除林下植被可以加快有机碳的分解,导致土壤有机碳含量降低和CO2排放增加;而增加林下植被可以增加土壤有机碳含量和土壤温室气体的排放;土地利用方式从天然林转变为其他土地利用方式(如次生林,农田,草地等),土壤有机碳含量均会下降和CO2排放增加.
The responses of soil carbon (C) pools and greenhouse gas (GHG) emissions to management practices of plantation were reviewed.Various management practices, such as fertilization, understory weeding, land-use change, etc. have a significant influence on soil C pools and GHGemissions. Studies reported that fertilization can markedly increase soil organic C (SOC) pools and soil GHG emissions in forest ecosystem, andunderstory weeding can decrease SOC content and increase soil CO2 emission. Changes of land-use from natural forest to other land use patterns(such as secondary forest, agricultural land, grassland, etc.) decreased significantly in SOC content and increased in soil CO2 emission.
