摘要
自工业革命以来,由于人类活动尤其是化石燃料的大量使用,大气CO_(2)浓度持续升高造成“温室效应”,引起了全球变暖等一系列气候变化问题。作为缓解气候变化的重要措施——减缓人类活动引起的CO_(2)排放“源”、增加自然生态系统CO_(2)的吸收“汇”,已在世界范围内得到广泛共识。
Plants fix CO_(2) through photosynthesis and enter the soil layer in the form of dead leaves,dead roots or their secretions,which are transformed into organic matters by animals,microorganisms and enzymes and stored in the soil,thus forming soil carbon sink.Climate and human activities are the main factors affecting soil carbon storage and the function of forest soil carbon sequestration.Forest land preparation,harvest intensity,rotation management,mixed multispecies plantation,disease and pest control and fire control can effectively reduce soil carbon emissions and thus increase the carbon sink function.
