| 摘要: |
| 参照《千年生态评估项目》的生态系统服务分类体系,构建了广西近海海洋生态系统服务功能体系。以2010年为评价基准年,采用市场价格法、替代成本法、成果参照法等评估方法,对广西近海海洋生态系统的10个核心服务价值进行了初步估算。结果:(1)广西近海海洋生态系统服务总价值为6.5228×1010元/a,相当于2010年广西全区GDP的6.82%,其中调节服务价值最大,占60.87%,其次为文化服务,占27.74%;(2)供给服务价值较小,占11.38%;(3)各亚类服务价值的排序为:气体调节 > 食品供给 > 气候调节 > 污染物处理 > 旅游娱乐 > 基因资源供给 > 干扰调节 > 科研文化 > 生物控制 > 原材料供给;(4)广西近海生态资源开发水平较低,但潜力巨大,同时要注重区域海洋生态环境保护。 |

| Abstract: |
| On the basis of ecosystem services classification system from Millennium Ecosystem Assessment Groups, offshore marine ecosystem service type system of Guangxi was built. The 10 service values of the core ecosystem functions were evaluated by market price method, replace cost method, results reference method etc. The results showed that 1) the annual total value of offshore marine ecosystem services of Guangxi was about 6.5228×1010 yuan in 2010,which is equal to 6.82% of the GDP produced by Guangxi in the same year; 2) supply service value, adjustment service and cultural accounted for 11.38%,60.87% and 27.74% of the total value of the marine ecosystem services, respectively; 3) the order of subcategory services value from high to low is gas regulation, food supply, climate regulation, waste disposal, tourism and entertainment, gene resources supply, disturbance regulation, scientific search and culture, biological control, and raw material provision; 4) The marine ecological resources were slowly developed but with great potential and the protection of the marine ecological environment also should be paid attention to. |
