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.
