黄淮海湿地系统分类体系构建

黄淮海平原是3条大河在时空演化过程中形成的,其内形成了复杂多样的湿地系统和类型.由于受强烈的人类活动影响,湿地系统演变的自然规律特性逐渐消失,明显受到人为调控下的水文情势制约,并在空间分布上也是持续萎缩,湿地系统的整体性联系被明显打破,景观破碎化、退化严重.构建一个符合现存湿地情形、宜于湿地管理的分类体系,对于保护和管理好湿地,发挥其功能具有重要意义.在湿地系统分类中,就人工湿地的划分,突出了其服务功能性质,有利于人工湿地的归类管理.

Constructing a Classification System of Wetlands in Huang-Huai-Hai Plain

There are complicated and various wetland systems in Huang-Huai-Hai Plain, which is resulted from the evolution of three rivers (Yellow River, Huaihe River and Haihe River) in time and space. The natural evolution characteristics gradually disappear and is restricted by the hydrological regime under artificial adjustment in these wetland systems, whose integrity is broken and landscape is fragmented seriously, due to the influence of human activities. In order to protect, manage and rationally utilize wetlands, it is important to construct an appropriate classification system that is coincident with the current pattern and benefcial to the future management. The ecological services of constructed wetlands are highlighted and a new type named as Ditch Wetland is added to the wetland classification system for facilitating the classification of constructed wetlands.
