摘要:
沼泽湿地是全球重要的碳库,在全球碳循环中发挥着举足轻重的作用。排水是沼泽湿地面临的主要人类活动干扰,在世界范围内广泛存在。排水后水位的改变引起沼泽湿地生态系统过程和功能的变化,进而对碳收支产生影响。本文基于中国知网和Web of Science数据库检索和筛选了65组数据(包括25组CO2 通量、18组CH4 通量和22组碳储量数据),综述了国内外排水对沼泽湿地碳通量和碳储量影响的研究。研究发现排水使沼泽湿地CH4与CO2通量改变,改变的幅度与湿地生态系统类型、排水时间及排水强度等因素有关。排水后CH4的排放通量降低了29-75%。CO2通量的不同组分响应不同:排水后生态系统呼吸增加了10.9-120%;总初级生产力的响应有很大的差异,可能升高也可能降低;净初级生产力有变化但不显著;净生态系统生产力多为显著降低,变化幅度为1.8--290.4%。排水对碳储量的影响更间接,多数研究表明排水后土壤碳储量显著降低,植被碳储量的变化不一致,与湿地类型和排水后的利用方式有关,存在不确定性。已有研究多以某一特定排水时间或排水强度的实验研究为主,未来应加强不同排水强度对碳通量和碳储量的影响研究,研究方法上要将控制实验、野外调查与模型模拟研究相结合,以深入理解排水对湿地生态系统碳收支的影响,为湿地保护和恢复提供理论依据。(图1 表4 参44)
Abstract:
As major types of wetlands, swamps, marshes and peatlands plays an important role in the global carbon cycle. Drainage, which is the main disturbance of these wetlands, caused water level drawdown and changes in ecosystem carbon budget. This paper aimed to review and integrate the drainage effects on carbon flux and carbon storage of swamps, marshes and peatlands of wordwilde. Based on Web of Science and China Knowledge Resource Integrated Database, we sumarrized a total of 65 datasets, including 25 sets of CO2 flux, 18 sets of CH4 flux, 22 sets of carbon storage. We tried to investigate drainage effects on carbon flux and storage of swamps, marshes and peatlands from worldwide. Literature analysis showed that t he CH4 flux significantly decreased 29-75% after draiange, while the ecosystem respiration significantly increased 10.9-120%. The gross primary production may increased or decreased after drainage. Most net ecosystem exchange from studies were significantly decreased, with varation of 1.8--290.4%. Compared to carbon flux, the impacts of drainage on carbon storage were indirect. Most studies revealed that soil organic carbon was significantly decreased after drainage, but responses of vegetation carbon were varied. The impacts of drainage on carbon flux and storage were varied with with wetland types, drainage history and extent of water level draw down. In order to provide better theoretical basis for wetland protection and restoration, future studies should put more attention on wetlands responses of different levels of water level draw down, and combined controlled experiments, field investigation and ecosystem modelling methods to deeply reveal how carbon flux and storage of swamps, marshes and mires response to drainage.
