摘　　要：为明确喀纳斯自然保护区森林生态系统具有的服务功能及其价值,采用《森林生态系统服务功能评估规范》(LY/T1721-2008)的方法,对2009、2014年喀纳斯自然保护区森林生态系统具有的生态服务功能及其价值进行评估。结果表明,2014年喀纳斯自然保护区森林生态系统总的服务功能价值比2009年增加了7.34%,且以涵养水源和生物多样性的价值量所占的比重为最大;灌木林地的功能价值增加率明显高于针叶林地和阔叶林地;不同森林类型所具有的服务功能及其价值主要差异明显。In order to clarify the value of forest ecosystem in the Kanas National Nature Reserve,and to provide scientific basis for ecosystem protection,seven indexes such as water and soil conservation,carbon fixation and oxygen release,nutrient accumulation,air purification,evaluation of biodiversity conservation and forest recreation services were used to evaluate their service functions and ecological values based on the specifications of assessment of forest ecosystem services in China （LY/T1721-2008）.The results showed that total value of forest ecosystem services functions in 2014 increased by 7.34% compared to 2009.The largest service function was found in water conservation and biodiversity.Coniferous forests had the highest functions in the values of water and soil conservation,carbon fixation and oxygen release,nutrient accumulation and biodiversity conservation.From 2009 to 2014,the value of shrub service function increased higher in water and soil conservation,carbon fixation and oxygen release,nutrient accumulation and biodiversity protection than those of coniferous forest and broad-leaf forest.There were significant differences among the different forest types and the value of service function.
