盐城沿海湿地退化原因及生态恢复措施研究

Causes of degradation and ecological restoration measures of coastal wetlands in Yancheng

受到人类活动和自然条件变化的影响,盐城沿海湿地面临着巨大的压力,湿地资源锐减、生态环境恶化,不利于湿地的可持续发展。文章概括了盐城湿地退化现状,分析并指出围垦、海平面上升、海岸侵蚀、环境污染、外来物种入侵、海岸带养殖等是导致湿地退化的原因,进一步针对滩涂湿地观测技术和理论发展、生态修复工程设置、外来物种管控措施和工程、潮滩生态修复格局和研究手段的提升等方面提出建议,为实现盐城沿海湿地科学发展及高效管理提供决策依据。

Affected by human activities and changes in natural conditions,coastal wetlands in Yancheng are under great pressure,resulting in a sharp decrease of wetland resources and deterioration of ecological environment,which is not conducive to the sustainable development of wetlands.This paper summarizes the present situation of Yancheng wetland degradation,and points out that reclamation,sea level rise,coastal erosion,environmental pollution,alien species invasion,coastal culture and other causes of wetland degradation,and further puts forward suggestions for the observation technology and theoretical development of beach wetland,ecological restoration project setting,alien species management and control measures and engineering,tidal flat ecological restoration pattern and research means to improve,and provides decision basis for the realization of scientific development and efficient management of Yancheng coastal wetlands.
