摘要
CO2是全球环境中一个重要的控制因子。大气中CO2的来源主要有海洋及地球内部的大量释放、矿物燃料的燃烧、地球植被系统的破坏等,而海洋及植物系统则扮演了吸收CO2的重要角色。大气中CO2的增多会引发一系列的生态效应,如全球变暖、海平面上升以及对农业的影响等。通过人工措施吸收、转化、贮存、利用CO2,可为削减大气中CO2的增长提供有效途径。在调研了国内外大量文献的基础上,对大气中CO2的源与汇以及含量增长对环境的影响进行了分析,并提出了几种控制CO2的措施。
Carbon dioxide （CO2） plays a key role in global environment changes. CO2 in atmosphere mainly comes from the release of ceean and earth, the burning of fossil fuels and the mining of plants. Ocean and plants also play a role as CO2 sink. The increase of CO2 concentration in atmosphere brings a series of ecological effects, such as global wanning, sea level rise, and also effects on agriculture. Methods of absorption, transformation, fixing and reuse can be effective approaches of reducing atmospheric CO2. The views of atmospheric CO2＇s source or sink and the effects of increasing CO2 on environment are analyzed based on the domestic and foreign references about tiffs domain. Finally, same methods controlling CO2 are introduced.
