摘 要:采用两阶抽样法,在生物量调查基础上,运用市场价值法、影子工程法、机会成本法等方法,对遂昌县226个公益林小班进行了实物量与价值量评价。结果显示:遂昌县公益林2010年总生物量1 395.80×104t,生态效益总价值90.59亿元。生物量大小依次为针阔混交林>杉木林>阔叶林>松木林>毛竹林>灌木林>杂竹林,不同服务功能价值量排序为涵养水源>生物多样性保护>固碳释氧>固土保肥>森林旅游>净化大气>森林防护>积累营养。研究表明,遂昌县公益林生态效益显著,间接价值远大于直接价值。研究认为生态系统各服务功能内在关系和量化指标选取对公益林生态效益评价有重要影响;加强公益林可持续管理,防止退化,是公益林生态效益下一步研究重点。Based on the biomass investigation by two-class sampling method, the market value method, shadow engineering method and opportunity cost method, the physical quantity and value quantity of 226 public welfare forest subcompartment in Suichang County was evaluated. The result showed that the total biomass of public welfare forest in Suichang County in 2010 was 1 395.80 x 104 T, and ecological value was 9. 059 billion yuan. The order of biomass was ranked as coniferous and broadleaved mixed forest 〉 Chinese fir 〉 broadleaved forest 〉 pine forests 〉 bamboo forest 〉 shrub forest 〉 mixed bamboo forest; and different service function value order was ranked as water conservation 〉 biological diversity protection 〉 carbon fixation and oxygen release 〉 soil fixation and fertility maintenance 〉 forest tourism 〉 air purification 〉 forest protection 〉 nutrients accumulation, suggesting that the eco-benefit of public welfare forest in Suichang was significant, and the indirect value was far greater than the direct value. We conclude that the inherent relation of the ecosystem service func- tion and the quantitative indicators selection have an important influence on the evaluation of the public welfare forest bene- fit. The further research will focus on the sustainable management of public welfare forest.
