【摘要】：湿地是地球上生物多样性最丰富、生产力最高、最具价值的生态系统之一,为人类社会经济的发展提供了重要保障.在高强度人类活动和气候变化双重作用下,湿地破碎化严重,面积减小,湿地的水文连通受阻,导致了一系列生态环境问题.本文基于广泛的文献调研,从水文连通的概念、水文连通对湿地生境的影响、水文连通对生物的影响以及受损水文连通的修复4个方面回顾了当前湿地水文连通的生态效应研究进展以及存在的不足.结合多年在湿地领域的研究背景,重点针对上下游重大人类活动和气候变化对大江大河三角洲湿地水文连通的胁迫,提出了未来的主要研究趋势,将为解决三角洲湿地面临的基础科学问题提供支持,推动我国湿地科学基础理论的发展.
[Abstract]:Wetland is one of the most abundant biodiversity, the highest productivity and the most valuable ecosystem on the earth, which provides an important guarantee for the development of human society and economy. Under the dual action of high intensity human activities and climate change, wetland fragmentation is serious, the area is reduced, and the hydrological connection of wetland is blocked, which leads to a series of ecological and environmental problems. In this paper, based on extensive literature research, from the concept of hydrological connectivity, the impact of hydrological connectivity on wetland habitat, The effects of hydrological connectivity on organisms and the restoration of damaged hydrological connectivity were reviewed in this paper. Combined with the research background in wetland field for many years, this paper puts forward the main research trend in the future, focusing on the stress of major human activities and climate change on the hydrological connectivity of wetlands in the Great River Delta. It will provide support for solving the basic scientific problems faced by the delta wetland and promote the development of the basic theory of wetland science in China.
