淳安县森林生态系统服务价值评估

基于森林资源二类调查数据，采用市场价值法、影子工程等方法，评估了浙江省淳安县森林生态系统主要服务价值。结果表明：2008年，淳安县森林生态系统服务总价值为224.04亿元，生态服务价值是社会经济服务价值的4.55倍。各项服务总价值和单位面积价值依次为保护土壤＞水源涵养＞森林旅游＞保护生物多样性＞净化环境＞固碳释氧＞提供林副产品；不同森林类型生态功能服务总价值依次为针叶林＞阔叶林＞灌木林＞针阔混交林＞竹林，而单位面积价值依次为阔叶林＞针阔混交林＞竹林＞针叶林＞灌木林。在同一类型生态服务中，阔叶林的涵养水源、固碳释氧、保育土壤和针叶林净化环境的单位面积价值较大。图1表3参18

Evaluation of forest ecosystem services in Chun'an County

This paper evaluated the main services of forest ecosystem in Chun＇an County,based on the second forest resources inventory data,and by applying the methods of market value and shadow project.The results indicated that the total value of forest ecosystem services was 224.04 billon yuan in 2008;the ecological value was 4.55 times the socio-economic value.The sequence of the service function values of forests was as follows：erosion controlwater storageforest travelbiodiversity conservationair quality purificationC fixation and O2 releaseprovision of forest byproducts.The sequence of the ecological value of different forest types was as follows：broadleaf forestshrubconiferbamboo.The sequence of the unit area value was broadleaf forestconiferbambooconiferous forestshrub.In the same type of ecological services,the broadleaf forest had larger unit area values of C fixation and O2 release;water storage and erosion control and the coniferous forest had larger air quality purification.
