摘要：本文采用涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境和生物多样性保护等9个功能指标,对湖北省三峡地区天然林生态系统服务功能价值进行评估。结果表明:湖北省三峡地区天然林生态系统服务价值为336.66亿元·年-1。其中,固碳释氧、涵养水源和生物多样性保护3项功能价值量最大,分别占该地区天然林生态系统服务总价值的34.94%,30.45%和29.00%;阔叶林生态系统服务功能价值量最大,占该地区天然林生态系统服务总价值的37.54%。固碳释氧、涵养水源和生物多样性保护等功能都发挥着重要的作用,阔叶林在湖北省三峡地区天然林生态系统中具有突出的功能。
The values of service functions of natural forest ecosystem in the Three Gorges Region within Hubei were assessed based on nine indices of ecological services functions including water conservation, soil conservation and fertilization, CO2 fixation and O2 generation, nutriment accumulation, air purification, biodiversity conservation. Results showed that the annual service value of natural forest ecosystem in the Three Gorges Region within Hubei was 33. 666 billion Yuan RMB. For different ecosystem services, the values of CO2 fixation and O2 generation function, water conservation function and biodiversity protection function were the highest and accounted for 34.94%, 30. 45% and 29,00% of the total, respectively; for the forest with different stands, the value of broad-leaf forest ecosystem service was the highest and accounted for 37.54%. It suggested that the CO2 fixation and O2 generation, water conservation and biodiversity conservation played very important roles, and the broad-leaf forest contributed an important function in the natural forest ecosystem in the Three Gorges Region within Hubei.
