河北滨海湿地生态系统服务供需特征与情景分析

Supply and demand characteristics and scenario analysis of coastal wetland ecosystem services in Hebei Province

  • 摘要: 滨海湿地处于海陆生态系统交错地带, 研究湿地面积变化带来的生态系统服务和人类福祉的变化, 可为湿地生态系统服务提升、近海岸生态环境保护与生态安全管理提供参考。本文通过分析河北滨海湿地面积变化, 对2000—2020年河北滨海湿地生态系统服务的供给量和社会对湿地生态系统服务需求量进行评估, 并以供需比定量分析了滨海湿地生态系统服务供需特征, 最后利用情景分析预测了2030年河北滨海湿地供需安全。结果表明: 1)河北滨海湿地生态安全受到威胁, 主要表现为自然湿地面积和湿地生态廊道面积减少。2)除水产品供给服务增加外, 河北滨海湿地的水资源供给、净化环境、调节洪水、固碳、释氧和美学景观等生态系统服务供给量均降低, 河北滨海区社会对湿地生态系统服务需求量均呈增加趋势。3)河北滨海湿地面积仅占河北滨海区全域面积的6.3%, 但其提供的调节洪水服务可以满足河北滨海区全域对其需求。4)河北滨海湿地调节洪水服务的生态安全状况较好, 水产品供给服务、水资源供给服务和净化环境服务是目前需要重点关注的生态安全问题, 是未来可能影响河北滨海湿地生态安全的隐患, 固碳、释氧和美学景观服务是未来河北滨海湿地生态安全发展中的短板。5)情景分析下, 湿地严格保护情景下生态系统服务供给量和供需比最高, 是河北滨海湿地生态系统未来发展的最好情景模式。

     

    Abstract: Coastal wetlands are located in ecotones of marine and terrestrial ecosystems. Studying the changes in ecosystem services and human well-being caused by wetland areas can provide a reference for improving wetland ecosystem services, protecting coastal ecological environments, and managing ecological security. This study analyzed the changes in the coastal wetland areas in the Hebei Province, evaluated the supply of ecosystem services and the social demand for wetland ecosystem services in Hebei Province from 2000 to 2020, and quantitatively analyzed the supply and demand characteristics of coastal wetland ecosystem services based on the supply and demand ratio. Finally, a scenario analysis was used to predict the supply and demand security of coastal wetlands in the Hebei Province by 2030. The results show that: 1) the ecological security of coastal wetlands in Hebei is threatened, mainly manifested by a reduction in natural wetland areas and wetland ecological corridors. 2) In addition to the increase in aquatic product supply service, the supply of ecosystem services, such as the water resource supply, environmental purification, flood regulation, carbon sequestration, oxygen release, and aesthetic landscapes in the Hebei coastal wetlands, has decreased. The demand for wetland ecosystem services by society in the Hebei coastal area has increased. 3) Coastal wetlands in Hebei account for only 6.3% of the total coastal area. Nevertheless, the flood regulation services that they provide meet the needs of the entire coastal area in Hebei. 4) Good ecological security status of the flood regulation services is present in the Hebei coastal wetlands. Aquatic product supply, water resource supply, and environmental purification services are currently key ecological security issues that require focus and are potential hazards that may affect the future ecological security of the Hebei coastal wetlands. Carbon sequestration, oxygen release, and aesthetic landscape services are shortcomings in the future development of ecological security in the Hebei coastal wetlands. 5) Under the scenario analysis, the scenario of strict wetland protection has the highest supply and demand ratio of ecosystem services, which is the best scenario model for the future development of the coastal wetland ecosystem in Hebei.
