摘要
运用《退耕还林工程生态效益监测评估技术与管理规范》评估方法,对贵州省退耕林分定位监测数据及工程森林资源进行分析,并对贵州省退耕还林工程涵养水源、保育土壤、固碳释氧、积累营养物资、净化大气环境、生物多样性保护功能进行了物质量及价值量评估。结果表明:贵州省退耕还林工程森林生态服务功能总价值为631.1亿元/a,各项生态服务功能价值量从大到小顺序依次为:涵养水源、保护生物多样性、固碳释氧、净化大气环境、保育土壤、积累营养物质。
By using evaluation method of ＂The technical standard and management specification of monitoring ecological benefits of cropland to forest project evaluation＂,monitoring data of forests positioning in Guizhou Province and forest resources were analyzed,materials quantity and value quantity evaluation was conducted on soil and water conservation,carbon fixation and oxygen releasing,accumulation of vegetative material,purification of atmosphere environment,protection of biodiversity in cropland to forest project in Guizhou Province.The results showed that the total value of forest ecosystem services in Guizhou areas was 6.31 × 1010 yuan.The values of the ecosystem services were in the following order：water conservation,biodiversity protection,carbon fixation and oxygen released,atmospheric environment purification,soil conservation,nutrient accumulation.
