摘　　要：为科学评估湛江红树林国家级自然保护区湿地生态系统最终服务价值,综合运用生态学和经济学方法,对2013年湛江红树林国家级自然保护区高桥和营仔小区湿地生态系统的供给、调节和文化3类10项最终生态服务进行评估。结果表明,2013年湛江红树林国家级自然保护区湿地生态系统总服务价值为191.95×10~6元。其中,海产品供给、气候调节和水质净化是湛江红树林国家级自然保护区湿地生态系统的3大核心服务功能,三者占服务总价值的73.17%。调节服务是其主要的服务类型,占总服务价值的55.99%。其中,固碳、大气组分调节和消浪护岸等调节服务功能较弱,仅占总服务价值的7.37%。该区湿地生态系统的单位服务价值为4.26元·m^(-2)·a^(-1),低于同纬度带内的红树林等自然生态系统,加强湿地保护与野外长期定位监测,并结合新的评估方法与研究手段,或可提高湛江红树林湿地服务功能及价值。Ecosystem service value assessments are crucial in ecological and environmental economics.Mangrove wetlands are an important component of coastal ecosystem.To estimate the wetland ecosystem service value in Zhanjiang Mangrove National Nature Reserve,ecological and economic methods were used to evaluate three kinds of final services including 10 indexes,of wetland ecosystem in Gaoqiao and Yingzai partitions in Zhanjiang Mangrove National Nature Reserve in 2013.Results showed that the total wetland ecosystem service value in the study area was 191.95×106 RMB yuan.The main functions of wetland ecosystems in Zhanjiang Mangrove National Nature Reserve were water supply,climate regulation,and water purification,the values of which accounted for 73.17%of the total ecosystem service value.The main service category was the regulating service,accounting for 55.99%of the total ecosystem service value.However,the contributions to the functions of carbon sequestration,atmospheric component regulation,and wave reduction and coastal protection were minor,the value of which was less than 7.37%of the total ecosystem service value.The average value of wetland ecosystems in Zhanjiang Mangrove National Nature Reserve was 4.26 RMB yuan·m-2·a-1,which was less than that of mangrove ecosystems of the same climate zone.It is necessary to improve wetland conservation,long-term field monitoring,as well as application of new methods to improve the Zhanjiang mangrove wetland ecosystem function and its service value in the future.
