摘要
以儋州林场公益林为研究对象,基于2008~2012年儋州林场资源二类调查数据,依据2008年国家林业局出台的《森林生态系统服务功能评估规范》(LY/T172 1-2008),对儋州林场公益林生态系统服务功能价值进行评估。评估结果:(1)儋州林场公益林生态系统服务功能价值量为23293.8848万元·a^(-1),固碳释氧(9866.7818万元·a^(-1))>涵养水源(8638.4801万元·a^(-1))>净化大气环境(2257.3860万元·a^(-1))>森林防护(913.9215万元·a^(-1))>生物多样性保护(770.4154万元·a^(-1))>积累营养物质(340.3664万元·a^(-1))>保育土壤(331.3843万元·a^(-1))>森林游憩(175.1494万元·a^(-1));(2)在不同森林林分类型公益林生态服务功能价值量中,用材林(16656.6605万元·a^(-1))>橡胶林(4734.1620万元·a^(-1))>灌草林(1246.6475万元·a^(-1))>防护林(631.5600万元·a^(-1))>次生林(24.8548万元·a^(-1));(3)不同类型公益林生态服务功能单位面积价值中,次生林(19.7260万元/hm^(2))>防护林(16.2983万元/hm^(2))>用材林(13.3657万元/hm^(2))>橡胶林(9.8902万元/hm^(2))>灌草林(6.8253万元/hm^(2))。
Taking the public welfare forest of Dan Zhou Forest farm as the study area, based on the two-class survey data of Dan Zhou Forest Field Resources in 2008~2012. According to the 2008 National Forestry Administration,the evaluation specification for ecosystem service functional evaluation(LY/T1721-2008),evaluated the value of the service function of the public welfare forest ecosystem in Dan Zhou Forest farm. The results follows:(1)Dan Zhou Forest Farm Public Welfare Forest Ecosystem Service Functional Value is 232,938,848 yuan a;,fixed carbon dioxide release oxygen(98,667,818 CNY·a^(-1))> conservation water source(86,384,801 CNY·a^(-1))> purify the atmospheric environment(22,573,860 CNY·a^(-1))>protection forest(9,139,215 CNY·a^(-1))> protection biodiversity(9,139,215 CNY·a^(-1))> accumulate nutrients(3,403,664 CNY·a^(-1))> conservation soil(3,313,843 CNY·a^(-1))> forest recreation(1,751,494 CNY·a^(-1)).(2)In different forestry categories of public welfare forest ecological service function,ingredients (166,566,605 CNY·a^(-1))> rubber(47,341,620 CNY·a^(-1))> grill forest(12,466,475 CNY·a^(-1))> protective forest(6,315,600 CNY·a^(-1))> secondary forest(248,548 CNY·a^(-1)).(3)Different types of public welfare forest ecosystem function unit area value,secondary forest(197,260 CNY/hm^(2))> protective forest(162,983 CNY/hm^(2))> ingredients(133,675 CNY/hm^(2))> Rubber(98,902 CNY/hm^(2))> grill forest(68,253 CNY/hm^(2)).
