大岗山森林生态系统服务功能及其价值评估

Assessment of forest ecosystem services value in Dagangshan

通过构建适合大岗山森林生态系统服务功能的评估指标体系,依据大岗山森林生态站长期、连续观测数据及多年科研成果、2次二类森林资源调查资料及社会经济公共数据估算大岗山"九五"和"十五"期间森林生态系统服务功能的总价值。结果表明:"九五"期间大岗山森林生态系统服务功能总价值平均为1亿8 495.00万元/a,单位面积价值为7.89万元/(hm2.a),"十五"期间为1亿9 180.00万元/a,单位面积价值为8.09万元/(hm2.a),总价值增长3.70%,单位面积价值增长2.63%;在7项森林生态系统服务功能中,"九五"和"十五"期间大小顺序依次均为涵养水源>固碳制氧>保护生物多样性>净化大气环境>保育土壤>林木营养积累>森林游憩与生态文化,"九五"和"十五"期间各森林类型总价值大小顺序均为毛竹林>杉木>硬阔类>软阔类>针阔混交类>灌木>马尾松,单位面积价值大小顺序均为硬阔类>软阔类>毛竹林>灌木>马尾松>针阔混交类>杉木。

A series of assessment index system suitable for Dagangshan forest ecosystem services value was set up. We assessed the economic value of forest ecosystem services of Dagangshan on the basis of the data of Dagangshan long-term observation, the forest resource of Dagangshan, and the data of social commonality. The resuits show that the total value of the Dagangshan＇ s forest ecosystem services is 184.95 million yuan per year in the period of ninth five years. The value of forest ecosystem services is 789 hundred yuan/（hm^2· a）. The total value of tenth five years is 191.80 million yuan per year,and 809 hundred yuan/（hm^2· a）. The value went up 3.70% and 2.63% respectively. In the seven types of services, the value order is water retention, carbon fixed and oxygen released biodiversity conservation, air environmental purification, soil conservation, forest nutrition storage, forest tourism and ecological culture. The value order of forest type is Phyllostachys edulis, Cunninghamia lanceolata, hard broadleaved forest, soft broadleaved forest, mixed forest of conifer and broadleaf, shrub, Pinus massoniana. The value order of tree species is hard broadleaved forest, soft broadleaved forest, PhyUostachys edulis, shrub, Pinus massoniana, mixed forest of conifer and broadleaf, Cunninghamia lanceolata.
