摘要：草丘湿地作为沼泽湿地中的独特景观,发挥着重要的生态功能,其独特的环境异质性和水文条件的影响使其成为研究热点。草丘湿地的形成与水文条件密切相关,水文条件的变化也影响草丘湿地的发展与演变。水文条件对草丘植物有直接影响,通过淹水条件直接影响草丘植物的物种分布、生理特征、形态结构、生长状况、生物量,以及草丘丘墩的高度、基面积、丘墩形状、分布密度及分布间距等特征,影响草丘植物与土壤间的反馈,进而影响草丘湿地的形成与演变进程和草丘湿地功能的发挥。水文条件促使草丘湿地产生独特的微地貌特征,并产生环境异质性,造成丘上与丘间水文环境特征的显著不同。水文条件通过调节植物?土壤反馈及微生物活性,对草丘湿地碳、氮循环过程和其“源”和“汇”功能的发挥产生影响。随着自然条件的变化及人为干扰的增强,草丘湿地结构破坏和功能退化现象逐年加重,如何充分运用水文条件的作用加速草丘湿地的恢复进程,并促进恢复草丘湿地充分发挥其“源”和“汇”功能,是草丘湿地恢复的关键。本文通过综述草丘湿地对水文条件的响应机制,分析了现有的草丘湿地恢复方法与不足,并提出利用水文响应规律促进草丘湿地结构和功能恢复的举措,以期为草丘湿地的保护与修复提供参考。
Tussock wetlands,serving as a unique landscape within marsh wetlands and performing vital ecological functions,have become a research hotspot due to their distinctive environmental heterogeneity and the influence of hydrological conditions.The formation of tussock wetlands is closely linked to hydrological conditions,and changes in these conditions also affect the development and evolution of tussock wetlands.Hydrological conditions exert a direct impact on tussock plants.Through flooding conditions,they directly influence the species distribution,physiological traits,morphological structure,growth status,and biomass of tussock plants,as well as the characteristics of tussock mounds such as height,basal area,mound shape,distribution density,and spacing.This affects the feedback between tussock plants and soil,thereby influencing the formation and evolution processes of tussock wetlands and the performance of their functions.Hydrological conditions drive the formation of unique micro-topographic features in tussock wetlands and generate environmental heterogeneity,resulting in markedly different hydrological environmental characteristics on-mound versus inter-mound.Hydrological conditions impact the carbon and nitrogen cycling processes and the functioning of their"source"and"sink"roles in tussock wetlands by regulating plant-soil feedback and microbial activity.With changes in natural conditions and increasing anthropogenic disturbances,structural damage and functional degradation of tussock wetlands are intensifying annually.How to fully utilize the role of hydrological conditions to accelerate the restoration process of tussock wetlands and promote the restored wetlands to fully realize their"source"and"sink"functions is key to tussock wetland restoration.This paper summarizes the response patterns of tussock wetlands to hydrological conditions,analyzes the existing restoration methods for tussock wetlands and their shortcomings,and proposes measures utilizing hydrological response patterns to promote the restoration of tussock wetland structure and function,aiming to provide references for the conservation and restoration of tussock wetlands.
