摘要
生态系统生源气体排放是全球C、N、S和Cl循环研究的重要内容,是当前全球变化生态学和生物地球化学循环的研究热点和焦点。在介绍海岸带盐沼生态系统生源气体种类及其环境效应的的基础上,重点对潮汐循环对植物枯落物分解和土壤生源要素生态化学计量学特征的影响、潮汐循环影响下电子受体和盐分输入特征及其对生源气体排放的影响、潮汐循环影响下生源气体生产者生态生理特征和生产者贡献比率变化特征、潮汐循环影响下海岸带盐沼高等植物根际生理生态过程以及海岸带盐沼潮周期内生源气体通量特征及其相互关系等关键科学问题和这些问题研究中的不确定性进行了探讨。为揭示C、N、S和Cl元素之间的相互作用及平衡制约关系和为减缓温室效应提供新思路和理论依据具有重要的现实意义。
Biogenic gases emission is an important aspect of study on global C,N,S,and Cl cycles.It has been a main focus of global change ecology and biogeochemical cycle research.In this paper firstly type of biogenic gases and their environmental effects are introduced,then key scientific issues and uncertainty of study on tidal cycling dynamic of biogenic gases emission are reviewed,especially status and focus of future research in the fields of biogenic gases emission.Discussion of key scientific issues and uncertainty of study on tidal cycling dynamic of biogenic gases emission can help us better understand tides and control factors of the biogenic gases production,conversion,and migration interaction.It is more important to reveal interaction among C,N,S,and Cl in order to provide insight and theoretical foundation for alleviation of greenhouse effects.
