摘　　要：论文根据生态系统服务功能,构建广西北部湾滨海湿地生态系统服务评价指标体系,对2012—2017年滨海湿地生态系统服务价值进行动态评估。结果表明:(1)供给服务是滨海湿地生态系统服务中最主要的功能,占总价值的44.42%,其中,物质生产和基因资源供给是供给服务功能的两大核心功能;(2)在调节服务中,供水和水质净化服务发展趋势不稳定,其余功能均呈现出先降低后平缓的趋势;(3)文化服务功能作用较小,但科研教育和滨海旅游的价值呈稳步增长趋势;(4)2012—2017年,广西北部湾滨海湿地生态系统服务功能的总价值分别为7 407.94×10~7元、7 099.68×10~7元、7 413.72×10~7元、7 830.46×10~7元、8 543.91×10~7元、9 491.36×10~7元,呈现出递增的发展趋势。该结果可为深入了解滨海湿地生态系统、合理利用滨海湿地及对其采取合理保护措施提供科学依据。According to ecosystem service function,the service evaluation index system of the coastal wetland ecosystem was constructed,and the service value of the coastal wetland ecosystem in Beibu Gulf of Guangxi from 2012 to 2017 was evaluated dynamically.The results show that:(1)Supply service is the most important function of the coastal wetland ecosystem service function in Beibu Gulf of Guangxi,accounting for 44.42%of the total value.The main functions of supply service are production of material products and the supply of genetic resources.(2)In the adjustment service,except for the service of water supply and the purification of water quality,which are in an unstable trend,other services are in a state of first reduction and then smooth development.(3)The overall role of cultural services is minimal,while the value of research and education and coastal tourism increase year by year and showed a steady growth trend.(4)The total value of ecosystem services of coastal wetlands for Beibu Gulf of Guangxi in 2012 to 2017 was 7407.94×107 Yuan,7099.68×107 Yuan,7413.72×107 Yuan,7830.46×107 Yuan,8543.91×107 Yuan,9491.36×107 Yuan,respectively,showing an increasing trend.The results can provide scientific basis for human beings to understand the coastal wetland ecosystem,make rational use of the coastal wetland and take protective measures.
