摘　　要：以甘肃省森林资源连续清查第五次复查(2006年)、第六次复查(2011年)、第七次复查(2016年)数据为研究对象,依据《森林生态系统服务功能评估规范》(LY/T 1721—2008),对2006—2016年甘肃省森林生态系统服务功能和价值进行了评估研究。结果表明,近年来,甘肃省森林生态系统服务功能价值呈增长态势,10年功能价值共增加了246.92亿元,增长了13.52%,年均增加24.69亿元,年均增长率为1.42%。在8项生态服务功能价值中,涵养水源、保育土壤、固碳释氧和生物多样性保护这4项功能发挥作用均较大,占有主体地位,其价值量之和的占比接近总价值的90%。Based on the data of the fifth(2006),sixth(2011)and seventh(2016)National Forest Resources Inventory in Gansu prov⁃ince,the function and value of forest ecosystem services in Gansu province from 2006 to 2016 was evaluated according to the Standard for Assessment of Forest Ecosystem Services Function(LY/T 1721—2008).The results showed that the value of forest ecosystem services in Gansu province showed an increasing trend in 2006—2016,with a total increase of 246.92 billion yuan,increased by 13.52%.The average increase of it was 2.469 billion yuan and the average annual growth rate of it was 1.42%.Among the eight ecological functions,water conservation,soil conservation,carbon sequestration and oxygen release,and biodiversity conservation play a significant role,occupying a dominant position.The value of the four functions together accounts for nearly 90%of the total value.
