以杭州市2021年森林资源动态监测数据为研究基础,依据《森林生态系统服务功能评估规范》,运用年金资本化法、重置成本法、收益现值法、市场倒算法、分布式测算法、市场价值替代法、文年评估法等方法综合核算杭州市森林资源价值,包括林地林木资源、森林生态价值服务、森林文化价值。结果表明:(1)杭州市2021年森林资源资产总价值1915.58亿元,其中林地林木价值699.23亿元,占36.50%,林木价值687.88亿元,林地价值11.35亿元。在林木价值占比中,乔木林>经济林>竹林。在林地价值占比中,乔木林地>竹林地>其他林地。(2)森林生态服务价值827.54亿元,占森林资源总价值的43.20%,森林生态系统服务价值内部构成排序为:涵养水源价值>生物多样性保护价值>固碳释氧价值>保育土壤价值>净化大气环境价值>森林防护价值。(3)森林文化价值388.81亿元,占比20.30%。

Based on the dynamic monitoring data of forest resources in Hangzhou in 2021,according to the“Forest Ecological System Services Evaluation Specifications”,by use of annuity capitalization method,reset cost method,income current value method,market inversion algorithm,distributed measurement method,market value replacement method and culture year assessment method,here,forest resources,forest ecological value services and forest cultural value were comprehensively accounted in Hangzhou.The results showed that:(1)The total value of forest resource assets in Hangzhou in 2021 was 191.558 billion RMB yuan,including the value of forest land of 69.923 billion RMB yuan(accounting for 36.50%),the value of forest trees of 68.788 billion RMB yuan,and the value of forest land of 1.135 billion RMB yuan.In the proportion of forest value,such an older as arbor forest>economic forest>bamboo forest was gained.Among the value of forest land,arbor land>bamboo forest land>other forest land gained in order.(2)In 2021,the value of forest ecological services was claimed as 82.754 billion RMB yuan(accounting for 43.20%of the total value of forest resources),and the internal composition of forest ecosystem service values was ranked as:water conservation value>biodiversity conservation value>carbon sequestration and oxygen release value>soil conservation value>atmospheric environment purification value>forest protection value.(3)The value of forest culture was gained of 38.881 billion RMB yuan,accounting for 20.30%.
