系统分析了生态系统服务功能及价值评估的研究进展,探讨了海洋生态系统服务功能及价值的内涵。以桑沟湾为例,对该生态系统的渔业生产、气体调节、污水处理、空气净化、滨海旅游、文化价值等服务功能的价值以2004年为评价基准年份进行了评价。评价结果为,2004年桑沟湾生态系统服务功能的价值为10.51×108元。其中直接经济价值(渔业生产)6.86×108元,占总服务价值的65.29%,表征桑沟湾是一个典型的养殖型海湾。这与人们对于桑沟湾的一般认识是一致的。同时我们注意到,桑沟湾生态系统的其他服务价值总和为3.65×108元,该数值占总服务价值的34.71%。作者认为,本文所得结果是桑沟湾也已实现了的生态服务价值,是对桑沟湾生态服务价值的保守估计。
Based on the analysis on the advance of the ecosystem service research,the connotation of marine ecosystem services is analyzed in detail.Taking Sanggou Bay as an example,the values of fishery production,gas regulation,wastewater treatment,cleaning the air,beach travel and culture service were assessed respectively.The result showed that the ecosystem services value of Sanggou Bay in 2004 is 10.5067×108 Yuan,and the direct economic value(i.e.,fishery production) is 6.86×108 Yuan which accounts for 65.29% of...
