湿地生态系统碳平衡及碳核算方法综述

摘要

湿地作为一种特珠的生态系统,在固碳方面也起到了举足轻重的作用.本文首先探讨了湿地生态系统的碳循环和碳平衡过程,然后介绍了当前国内外普遍运用的几种碳汇计童方法,包括生物量法、静态箱法、动态箱法、GIS法、同位素法、涡旋相关法、涡度协方差法等,并对这些方法的优缺点进行了分析,对未来湿地碳平衡及碳核算方法的研究进行了展望.%As a special ecosystem, wetlands play a pivotal role on carbon sequestration. This paper firstly discussed the carbon cycle and carbon balance of the wetlands ecosystem, and then introduced several common methods for carbon accounting,including the method on biomass, the static chamber method, dynamic chamber method, GIS, isotope method, eddy correlation,eddy covariance and so on. Furthermore, the advantages and disadvantages of these methods were analyzed, and the future research on the methods of carbon balance and carbon accounting for wetlands ecosystem was prospected.
