| 摘 要： | 人类活动导致大气中温室气体浓度增加,是全球气候变暖的主要原因之一。由于陆地生态系统中通气状况良好的土壤是甲烷最大的吸收汇,研究吸收汇强度及其影响因素对估算大气中甲烷储存增量、采取措施增强土壤吸收汇的强度是很有意义的。综述了全球透气土壤吸收甲烷总量及土地利用变化、农业措施对甲烷吸收汇的影响。

| Abstract: | Aerobic soil in terrestrial ecosystem is the greatest methane sink, it contributes significantly to the atmospheric methane budget. It is important to study the sink strength and the influence factors for the purpose of balancing the methane in atmosphere and taking measures for increasing the uptake capability. The paper reviews the impact of land use change, soil temperature, soil pH, and agricultural practice such as irrigation, fertilizer application on soil consumption of atmospheric methane. Results indicate that atmospheric methane consumption is especially sensitive to anthropogenic disturbances, which typically decrease the consumption capacity. |
