摘 要: | 广西九万山自然保护区是以中亚热带常绿阔叶林及其垂直带谱为主的森林生态系统及珍惜濒危动植物为主要保护对象的国家级自然保护区,对区域与国家都有着重要的生态服务价值。经过实地调研,应用市场价值、机会成本、影子价格等方法对九万山国家级自然保护区内提供林木产品、涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境、生物多样性保护等森林生态服务价值功能进行评估。结果表明:九万山国家级自然保护区森林生态系统服务功能总价值226 533.30万元/年。其中涵养水源(132 198.24万元/年)保护生物多样性(42 241.14万元/年)固碳释氧(37 433.96万元/年)保育土壤(9 624.30万元/年)林木产品(4 543万元/年)净化大气环境(266.92万元/年)积累营养物质(225.76万元/年)。

Abstract: | Jiuwan Mountain Nature Reserve is a National Nature Reserve,which mainly contains the subtropical ever-green broadleaf forest and vertical band based forest ecosystems and also cherishes endangered species as the main protec-tion objects,so that it has an important ecological value services on the region and nation. After field research,we make an evaluation on the value function of forest ecosystem service such as forest products,water conservation,soil conserva-tion,carbon sequestration and oxygen release,accumulation of nutrients,atmosphere purificaiton,biodiversity conserva-tion by application market value,opportunity cost,shadow price methods. The results showed that,the total value of for-est ecosystem services of Jiuwan Mountion National Nature Reserve was 2 265.33 million yuan per year. And water con-servation (1 321.98 million yuan per year) >conservation of biological diversity (422.41 million yuan per year) >carbon sequestration and oxygen release (374.33 million yuan per year) >soil conservation (96.24 million yuan per year) >wood products (45.43 million yuan per year) >purify the atmosphere (2.66 million yuan per year) >ac-cumulation of nutrients (2.25 million yuan per year). |
