温室气体源汇及其对气候影响的研究进展

Greenhouse gas and its affect on weather

从与人类活动密切相关的温室气体(CO2、CH4、N2O)源汇研究以及温室气体对气候环境的影响等方面论述温室气体研究进展。介绍了国内外有关温室气体源和汇研究,如岩溶系统碳循环、黄土中温室气体组分特征、森林和大陆边缘海二氧化碳、稻田和湿地甲烷排放等方面的研究成果和认识。介绍了冰芯温室气体的部分研究成果和国内外温室气体与气候关系研究中涉及的一些模式及重要结论。结合温室气体源汇及其与气候变化,指出了目前应重视的一些研究内容,如研究陆地和海洋生态系统的碳氮循环问题,温室气体浓度变化与气候变化的相互关系以及气候变化机制。

The greenhouse gas source and sink related to the human being＇s activity and its affect on the climate change is described. The source and sink research such as the carbon cycle in the karst system, the characteristic of the greenhouse gas component in the loess, the carbon dioxide in the forest and sea next to continent and the methane release in the paddy field and wet land is introduced. The research direction such as the carbon and nitrogen cycle in the terrestrial and marine ecosystems and the relationship and influence mechanism between the greenhouse gas and climate change is also introduced.
