摘要:

互花米草(Spartina alterniflora)引入中国30余年,其生态效应受到广泛关注。本文总结了在互花米草盐沼土壤碳循环中用到的关键研究方法、研究技术和相关成果,包括盐沼土壤有机质分组方法,海滨湿地有机碳结构、来源及判定方法,以及相关研究结果。未来研究方向建议:加强不同区域和不同环境条件之间的比较研究;加强多种新技术手段的综合应用;滨海盐沼湿地碳与邻近生态系统之间的交换通量核算与监测;加强盐沼碳赋存控制因素的研究,预测全球变化和人类活动对碳循环的影响机制,提升我国盐沼固碳能力。

Spartina alterniflora was introduced in China in 1979 and the ecological effects on local coastal wetlands have been discussed. This paper reviewed the popular methods, technologies and results in S. alterniflora salt mash soil carbon cycling, including the soil organic carbon separation methods, salt marsh soil organic carbon structure, carbon sources identification measures and related results. Suggestions were presented as: more S. alterniflora salt marsh study regions should be covered and compared; multiple technologies and methods were advised to be utilized and verified; carbon exchanges fluxes between S. alterniflora salt marsh and neighboring ecosystems should be examined and monitored; S. alterniflora salt marsh carbon sequestration driven factors are valuable issues, as well as the human activities and global changes affecting mechanism on salt marsh carbon cycling, which will contribute to its functions as carbon sink.
