以浙江省国有林场为研究对象,利用森林资源二类调查数据和样地实测数据,运用生物量二元模型、碳税法等,评估浙江省国有林场森林固碳释氧服务功能价值。结果表明:浙江省国有林场阔叶林、针阔混交林、松林、杉木林和其他5种主要植被类型单位面积碳储量分别为110.45,92.31,74.66,56.95和44.69 t/hm2,均明显高于全省森林植被平均碳储量(44.47 t/hm2)。浙江省国有林场森林面积占全省的3.69%,吸收二氧化碳、释放氧气量均占全省的5.01%。全省国有林场每年平均吸收二氧化碳量为14.89 t/(hm2·a),每年平均释放氧气量为10.87 t/(hm2·a)。全省国有林场年固碳释氧总价值为67.81亿元/a,其中,固碳价值42.16亿元/a,释氧价值25.65亿元/a。固碳释氧量及价值依次均为阔叶林>针阔混交林>松林>杉木林>其它。

Taking the state-owned forest farms in Zhejiang Province as the research object,the values of forest carbon sequestration and oxygen release service were evaluated by using the forest resource data and the measured data of the sample plots,with the biomass models and the carbon tax method.The results showed:The carbon storage of broad-leaved forest,coniferous and broad-leaved mixed forest,pine forest,Cunninghamia lanceolata forest and others in Zhejiang state-owned forest farms were 110.45 t/hm2,92.31 t/hm2,74.66 t/hm2,56.95 t/hm2 and 44.69 t/hm2 respectively.Those were significantly higher than the average carbon storage of Zhejiang forest vegetation (44.47 t/hm2).The state-owned forest farms,accounting for 3.69% of the total forest area in Zhejiang,contributed 5.01% amounts of CO2 absorbed and O2 released by forests in Zhejiang.The average amounts of CO2 absorbed and O2 released by forest vegetation of the state-owned forest farms of Zhejiang Province were 14.89 t/(hm2·a) and 10.87 t/(hm2·a) respectively.The value of carbon fixation and oxygen release was 67.81×108 yuan/a.The value of carbon sequestration was 42.16×108 yuan/a,and the value of oxygen release value was 25.65×108 yuan/a.The order of the amounts and values of carbon sequestration and oxygen release was the broad-leaved forest>coniferous and broad-leaved mixed forest>pine forest>Cunninghamia lanceolata forest>others.
