湿地生态系统固碳潜力研究进展

Advance in the studies on carbon sequestration potential of wetland ecosystem

固碳是湿地生态系统一项重要的服务功能。文章通过对各种类型湿地的固碳量及其潜力进行分析,发现湿地的固碳潜力要高于其他类型的生态系统,维持和恢复湿地的固碳潜力对全球碳循环具有重要的意义。如果湿地遭到破坏或转为他用,其固碳能力就会随之下降,所以保护湿地是保证湿地固碳潜力优先考虑的管理措施。此外通过对泥炭湿地、沿海湿地、森林湿地和人工湿地的恢复措施及效果的分析,发现恢复和创造湿地可以恢复并增强湿地生态系统的固碳潜力,但针对湿地碳库的固碳措施需要进一步的探索和实践。

Carbon fixation was one of the important ecosystem services of wetland. In this paper, carbon sequestration potential of kinds of wetlands were discussed, which were much higher than other ecosystems. Thus, substantial and restore the sequestration potential were important to global carbon cycle. Once wetlands were destroyed or turned to other use, the sequestration potential decreased correspondingly. So protection of wetlands was a technique recommended for carbon sequestration. Another important way was the restoration and creation of wetlands, which was proved feasible by analyzing the managements and results of the restoration of peatlands, coastal wetlands, forest wetlands and constructed wetlands.
