全球变化对森林土壤甲烷吸收的影响及其机制研究进展
|
摘要
大气CO_2浓度升高、降水格局改变、全球氮沉降增加和土地覆盖变化等全球变化不仅改变了森林土壤理化性质,而且影响了植物的生长和微生物活性,导致森林土壤碳、氮循环发生改变,进而影响土壤CH_4的吸收.本研究综述了森林土壤CH_4吸收的重要性,森林土壤CH_4吸收对大气CO_2浓度升高、降水格局改变、全球氮沉降增加和土地覆盖变化等全球变化的响应差异及驱动机制.大气CO_2浓度升高抑制土壤CH_4吸收;降水减少倾向于促进土壤CH_4吸收;外源氮输入抑制富氮森林土壤CH_4吸收,而对贫氮森林土壤CH_4吸收则表现为促进或不影响;森林转化为草地、农田或人工林会减少土壤CH_4的吸收量,而植树造林则会增加土壤CH_4的吸收量.今后的研究重点是探讨全球变化对森林土壤CH_4吸收产生长期影响和综合效应,并借助分子生物学方法进一步探究土壤CH_4吸收的微生物学机制.
Elevated atmospheric CO_2 concentration,altered precipitation regime,increased nitrogen deposition,and land cover change have not only changed the physical and chemical properties of forest soils,but also affected plant growth and microbial activity,with concequences on soil carbon and nitrogen cycles,including soil CH_4 uptake. In this study,we summarized the important role of soil CH_4 uptake in forests under global change scenarios. The differences of responses as well as the underlying mechanisms of soil CH_4 uptake in forests to global change were reviewed. Elevated atmospheric CO_2 concentration inhibits soil CH_4 uptake. Reduced precipitation tends to promote soil CH_4 uptake. Increased nitrogen input inhibits soil CH_4 uptake in nitrogen-rich forests,but promotes or has no effects on soil CH_4 uptake in nitrogen-poor forests. Conversion of forests to grassland,farmland,or plantations would reduce soil CH_4 uptake,while afforestation increases soil CH_4 uptake. The future research should explore the long-term and multiple effects of global changes on forest soil CH_4 uptake. In addition,molecular biology methods should be developed to explore the microbial mechanism of soil CH_4 uptake.
