摘　　要：对滨海湿地生态系统服务价值进行评价是保护和合理开发利用湿地以及制定湿地补偿政策的基础和依据。在借鉴湿地生态系统服务分类的基础上,尝试构建了广西滨海湿地生态服务价值评价体系,运用目前国内外较为成熟的湿地生态服务价值评价理论和评价方法以及湿地相关调查和最新遥感解译数据对2001和2009年广西滨海湿地生态系统服务价值分别进行了评价并做了对比分析。结果表明,2001和2009年广西滨海湿地生态系统生态服务总价值分别为506.70和328.36亿元,2009年湿地生态服务价值较2001年下降了178.34亿元,下降比例为35.20%。造成湿地生态服务价值下降的主要原因是湿地面积的大幅减少,面积从2001年的333 346 hm2减少到2009年的261 018.11 hm2,减少了21.70%。Evaluating the value of coastal wetlands ecosystem services is basis and foundation of protection and rational development and use of wetlands and the development of wetland compensation policy. Based on reference to classification of wetland ecosystem services, evaluation system of coastal wetland ecosystem service of Guangxi was built. International and domestic mature evaluation theory and methods of wetland ecosystem service value and the latest remote sensing interpretation data were used to evaluate and analyze the value of coastal wetland ecosystem service in 2001 and 2009 in Guangxi. The results indicate that the total value of coastal wetland ecosystem services of Guangxi is about 50.670 billion yuan in 2001 and 32.836 billion yuan in 2009. The value of wetland ecosystem services dropped 17.834 billion yuan from 2001 to 2009, and the percentage is 35.20%. The reason of decline in the value of wetland ecosystem services is mainly due to a significant reduction in wetland area. The area reduced from 333 3346 hm2 in 2001 to 261 018.11 hm2 in 2009, and the reduction percentage is about 21.70%.
