摘要
以能值理论为基础,对辽宁双台河口湿地生态系统服务进行价值评价。根据研究区的基本情况,将双台河口湿地生态系统服务划分为3大类、6小项,分别为供给服务:水产品供给、植物资源供给;调节服务:大气组分调节、水资源调节、生物栖息地;文化服务:科研文化。结果表明:双台河口湿地总能值价值为700.59亿元。其中,供给服务价值为15.10亿元,调节服务价值为670.32亿元,科研文化价值为15.17亿元。在整个双台河口湿地价值中,生物栖息地价值及水资源调节价值所占比例最大,分别为76.23%和19.44%。
Based on the theory of emergy value, the service value of wetland ecosystem in Liaoning province was evaluated. According to the basic situation of the research area, the Shuangtai estuary wetland ecosystem services are categorized into three categories, six items： provision services： aquatic products and plant resources services; regulation services： atmospheric composition regulation, water resources regulation and habitat services; cultural services： scientific research service. Results showed that the total emergy value of the Shuangtai estuary wetland was RMB 700.59×108. The provision services value accounted for RMB 15.10×108, regulation services value for RMB 670.32×108, and the value of culture services for RMB 15.17×108. Habitat and water resources regulation accounted for 76.23% and 19.44%, respectively, which is the leading service of total emergy value.
