海岸带湿地生态系统是重要的生态基础设施，与海岸带的可持续性密切相关。快速的城市化进程导致了我国沿海围垦的大量需求，随之而来的是滨海湿地的丧失和退化。本文以中国东部沿海农业型城市连云港为例，提出了一种适用于不同类型海岸带生态系统服务价值量化和海岸带围垦损失评估的修正模型。我们重点研究了与农业相关的四个主要生态系统服务：粮食生产、原材料供应、干扰调节和水净化。结果表明：32，346公顷沿海湿地的损失导致生态系统服务年损失8.06亿美元。改进后的生态系统服务价值评估模型能够实现海岸带生态基础设施的分类管理。同时，本研究还探讨了如何将生态系统服务价值评估与海岸带生态基础设施的评估、管理、规划、恢复和补偿相结合。
The coastal wetland ecosystems are the critical ecological infrastructure and have a close relation to coastal sustainability. Rapid urbanization lead to a big demand of coastal reclamation in China thereafter caused the loss and degradation of coastal wetlands. In this study, we presented modified model suitable for quantifying ecosystem service values of different coastal system subtypes and assessing their loss due to coastal reclamations with a case of coastal agriculture-dominated city of Eastern China (Lianyungang). We focused on four major agriculture-related ecosystem services as follows: food production, raw material supply, disturbance regulation, and water purification. The results showed that: 32,346 ha of loss in coastal wetlands resulted in US$ 806 million year−1loss in ecosystem service. The modified ecosystem service valuing models enable achieving categorized management of coastal ecological infrastructures. Furthermore, this study showed how to integrate the ecosystem service estimate into assessment, management, planning, restoration, and compensations of coastal ecological infrastructures.
