摘要
依据定量化目标和相应的资料获得性,确定了滨海湿地退化评估的8个指标,并对指标的估值方法作了规定,将滨海湿地的退化划分为5个等级。对我国28个滨海湿地区段的退化状况进行估值,属严重退化的4个、中度退化的14个、轻度退化的10个。导致我国滨海湿地退化的主要原因,包括了气候变化、海洋灾害等自然过程为主导的因素,也包括了海岸带围垦、海岸工程建筑、生物资源过度利用、环境污染等人为作用为主的因素。据此,缓解滨海湿地退化、改善滨海湿地环境的主要对策应包括制度体制的完善、自然保护区的建设、管理体系的协调发展、生态补偿制度的建立等。
According to the quantified goal and the acquirability of corresponding data, we determined 8 indicators for evaluating coastal wetland degradation,and defined the evaluation method. The coastal wetland degradation was divided into 5 levels. Twenty eight areas of coastal wetland in China were evaluated,and 4,14 and 10 areas belonged respectively to be seriously degraded,moderately degraded and lightly degraded. The main reasons leading to coastal wetlands degradation in China involved natural factors,such as climate change and marine disasters,etc. and also involved human activities,such as coastal reclamation,coastal engineering,over-exploitation of biological resources,environmental pollution and so on. Hereby,the main countermeasures to mitigate degradation and improve the environment of coastal wetland should include the improvement of system institution,construction of nature reserves, coordinated development of management system,and establishment of ecological compensation system.
