基于河流四维过程的河漫滩湿地生态景观恢复研究

A Study of Wetland Landscape Based on Four Dimensional River Process

河漫滩生态系统是脆弱的生态系统,同时受到人类活动和洪水干扰的影响,人类不合理侵占土地破坏生态,使河漫滩逐步丧失了原有的生态涵养、调蓄洪水功能,是河流的健康发展的重要障碍。因此,河漫滩地区的景观生态修复与重建极为迫切。以吉林省大安市嫩江湾国家湿地公园为研究对象,通过实地调查、咨询专家和查阅相关文献资料,主要从河漫滩湿地退化地区水文过程特征进行研究分析形成规划策略体系,为东北地区河漫滩湿地生态修复规划提供借鉴和参考。

River Beach ecosystem is a fragile ecosystem, which is influenced by human activities and flood disturbance. Human unreasonably encroaches on the land to destroy ecology, and gradually lose the original ecological conservation and flood control function, which is an important obstacle to the healthy development of rivers. Therefore, landscape ecological restoration and reconstruction in floodplain area is extremely urgent. Taking the Nenjiang Bay National Wetland Park in Da＇an City of Jilin as the research object, through field investigation, consulting experts and consulting related documents, the hydrological process characteristics of the degraded areas of the river beach wetland are mainly studied and analyzed to form a planning strategy system, which can provide reference for the ecological restoration planning of the flood land in the northeast of the river.
