基于中国陆地生态系统通量观测研究网络(ChinaFlux)3年(2005-2007年)的观测数据,研究了千烟洲中亚热带人工林(QYF)和长白山温带混交林(CBF)的气体调节通量动态和气体调节价值累积过程.本文将气体调节服务区分为值被气体调节服务和净生态系统气体调节服务.采用碳税法、造林成本法和工业制氧法对气体调节服务价值化,研究表明气体调节通量具有显著的季节变化.千烟洲人工林和长白山混交林植被的日均CO_2吸收量分别为82.00kg·hm~(-2)·d~(-1)和59.37kg·hm~(-2)·d~(-1),对应的O_2通量分别为59.65 kg·hm~(-2)·d~(-1)和43.19kg·hm~(-2)·d~(-1).千烟洲人工林和长白山混交林的植被气体调节价值累积过程曲线均为S型,年均植被气体调节服务价值分别为14342.69元·hm~(-2)和10384.18元·hm~(-2).就净生态系统气体调节服务而言,千烟洲人工林全年各月均表现为CO_2的净吸收和O_2的净释放,而长白山混交林则主要在5-9月表现为CO_2的净吸收.千烟洲人工林的净生态系统气体调节价值累积过程曲线为S型,而长白山混交林则为单峰型.千烟洲人工林和长白山混交林的年均净生态系统气体调节服务价值分别为8470.52元·hm~(-2)和5091.98元·hm~(-2).植被气体调节服务和净生态系统气体调节服务主要发生为5-10月.

Using the 3-year observational data from ChinaFlux (Chinese Terrestrial Ecosystem Flux Research Network), we studied the gas regulation flux dynamics and cumulative process of gas regulation value in Qianyanzhou middle subtropical plantation (QYF) and Changbai Mountain temperate mixed forest (CBF). The gas regulation service was differentiated into vegetation gas regulation service and net ecosystem gas regulation service. Carbon tax approach, reforestation cost approach and industrial oxygen approach were employed to calculate gas regulation value. Results show that there was significant seasonal variation in vegetation gas regulation flux. Daily CO_2 uptake fluxes averaged 82.00 kg·ha~(-1)·d~(-1) and 59.37 kg·ha~(-1)·d~(-1) and the corresponding O_2 emission fluxes were 59.65 kg·ha~(-1)·d~(-1) and 43.19 kg·ha~(-1)·d~(-1) for QYF and CBF, respectively. The cumulative curves of vegetation gas regulation value always followed a sigmoid shape, and the annual gas regulation value produced by vegetation was RMB 14342.69 yuan·ha~(-1) and RMB 10384.18 yuan·ha~(-1) for both QYF and CBF, respectively. In terms of monthly net ecosystem gas regulation service, QYF appeared as a CO_2 sink and O_2 source for the whole year, while CBF appeared to be a CO_2 sink and O_2 source mainly in the period between May and September. The cumulative curves of net ecosystem gas regulation value presented a sigmoid ("S") shape for QYF, while a unimodal type curve for CBF. The annual net ecosystem gas regulation value was 8470.52 yuan·ha~(-1) and 5091.98 yuan·ha~(-1) for QYF and CBF, respectively. The economic value of both the vegetation gas regulation service and net ecosystem gas regulation service were mainly produced between May and October.
