【摘要】 以截至2017年底贵州省十个重点监测县退耕还林资源量为基础,采用分布式测算方法,测算十个重点监测县退耕还林工程在涵养水源、保育土壤、固碳制氧、净化大气环境、林木积累营养物质、保护生物多样性等方面所产生的生态效益。结果表明:十个重点监测县退耕还林工程取得了巨大的生态效益,总价值为458030. 87万元/年,生态服务功能价值量从大到小顺序依次为:涵养水源(143379. 68万元/年),固碳释氧(105254. 02万元/年),净化大气环境(103300. 07万元/年),保育土壤(56277. 50万元/年),生物多样性保护(39751. 12万元/年),林木积累营养物质(10068. 48万元/年)。更多还原

【Abstract】 Based on the resource of returning farmland to forest in 10 key monitoring counties of Guizhou Province by the end of 2017,The ecological benefits of returning farmland to forestry project in 10 key monitoring counties were assessed with the distributed measurement method for water conservation,soil conservation,carbon fixation and oxygen release,air quality purification,nutrient accumulation and biodiversity conservation. The results show that the returning farmland to forestry project in 10 key monitoring counties has achieved tremendous ecological effects. The total value was458030. 87 million yuan( RMB),The values of the ecosystem services were in the following order: water conservation( 143379. 68 million yuan),carbon fixation and oxygen release( 105254. 02 million yuan),air quality purification( 103300. 07 million yuan),soil conservation( 56277. 50 million yuan),biodiversity conservation( 39751. 12 million yuan),nutrient accumulation( 10068. 48 million yuan).更多还原
