神农架森林生态系统服务价值估算

Assessment on Eco-service Functions of Forest Ecosystem in Shennongjia

依据《森林生态系统服务功能评估规范》,基于神农架森林生态系统长期连续定位观测的数据,并参考已有的研究文献,定量评估了神农架森林生态系统涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境以及生物多样性保护六大服务功能的价值量。结果表明:神农架森林生态系统六大服务功能总价值每年可达671.63亿元,其中保育土壤353.15亿元,涵养水源174.59亿元,固碳释氧60.62亿元,生物多样性保护72.79亿元,净化大气环境7.44亿元,积累营养物质3.04亿元。各植被类型的生态系统服务功能价值分别为阔叶林365.30亿元/a,针阔混交林206.29亿元/a,针叶林100.04亿元/a。研究结果将为神农架森林生态系统保护与发展提供科学依据。

Based on the Forest Ecosystem Services Assessment Standards issued by the state administration of forestry and the field scientific observation data,the ecosystem service values of each type of forest have been assessed quantitatively in Shennongjia. The results show that the total annual value of the ecosystem service function is 67. 163 billion yuan（ RMB）,of which 35. 315 billion yuan for soil conservation,17. 459 billion yuan for water conservation,6. 062 billion yuan for carbon fixation and oxygen released,7. 279 billion yuan for species conservation,0. 744 billion yuan for air purification and 0. 304 billion yuan for nutrient accumulation. The value of ecosystem services in various vegetation types are broad-leaved forest： 36. 530 billion yuan; theropencedrymion： 20. 629 billion yuan; coniferous forests： 10. 002 billion yuan.The results will provide basic data for constructing the ecosystem of forest in Shennongjia.
