林业活动在吸收大气CO_2与减缓全球变暖中的作用

The Role of Forestry Activities in Carbon Sequestration and Mitigation of Global Warming

森林生态系统是陆地生态系统的重要组分 ,对全球气候变化有重要的贡献。介绍了吸收大气CO2 和减缓全球变暖的林业活动的主要形式 ,即保存现有碳、固定大气碳和替代碳排放 ,论述了全球和我国森林碳保存及其固定潜力 。

Forest ecosystem is a key component of terrestrial ecosystem, and has the potential to contribute to global climate change through their influence on the global carbon cycle. In this paper, three categories of promising forestry activities that promote sound management of forests and at the same time conserve and sequester carbon, namely (1) Carbon conservation, (2) Carbon sequestration, and (3) Carbon substitution, are introduced. Meanwhile, the potentials of carbon conservation and sequestration in global forest and in Chinese forest are discussed. Finally, some suggestions are put forward in order to carry out these forestry activities effectively.
