长沙市主要森林类型生态服务功能价值评价

Evaluation of eco-service functions of major forest types in Changsha City

依据国家林业局发布的《森林生态系统服务功能评价规范》(LY/T1721-2008)标准评价了长沙市5种主要森林类型的生态服务功能总价值。结果表明:5种主要森林类型的生态服务功能总价值每年为272.094亿元,其中涵养水源为127.692亿元,保育土壤为21.8亿元,固碳释氧为62.346亿元,积累营养物质为3.631亿元,净化大气环境为20.947亿元,生物多样性保护为35.669亿元,森林游憩为0.009 026亿元。研究结果将为湖南省长株潭两型社会构建、绿色GDP核算提供基础数据。
