气候变化已经成为人类21世纪最大的挑战之一,因此受到了前所未有的关注。温室气体排放是气候变化重要的成因。甲烷是继二氧化碳之后最为重要的一种含碳温室气体,其产生、氧化以及排放机制受到了广泛聚焦:作为大气甲烷重要源,湿地甲烷通量及其相关生态过程的研究已经是全球变化生态学研究的热点和前沿之一。《全球变化与地球系统科学系列·中国特有湿地甲烷排放:案例研究、整合分析与模型模拟》从生态学、湿地科学、分子生态学及生态模型等学科出发,全面系统地阐释中国特有湿地甲烷排放及其相关过程。
《全球变化与地球系统科学系列·中国特有湿地甲烷排放:案例研究、整合分析与模型模拟》共分6章,第1章阐述了甲烷及湿地甲烷排放的机理和常识;第2章系统介绍我国特有的若尔盖高原湿地甲烷排放系统,包括若尔盖湿地甲烷排放的昼夜动态、季节动态、年际动态及其不同尺度的空间异质性;第3章介绍我国特有的三峡水库水面及消落带甲烷排放的特征;第4章介绍若尔盖湿地甲烷菌群落及其结构特征;第5章整合分析了我国稻田、自然湿地及湖泊甲烷排放并对这三个甲烷源重新估计;第6 章提供了湿地甲烷模型及其验证。
