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植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CO2吸收量分别为82.00kg·hm2·d-1和59.37kg·hm-2·d-1,对应的O2通量分别为59.65kg·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CO2的净吸收和O2的净释放,而长白山混交林则主要在5-9月表现为CO2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。图4表1参21。
Based on the observed data of ChinaFlux for three years (2005-2007), the gas fluxes of QiYanzhou subtropical plantation (QYF) and Changbai Mountain temperate mixed forest (CBF) were studied Dynamic and gas regulation value accumulation process. This article divides gas regulation services into vegetation gas regulation services and net ecosystem gas regulation services. Using carbon tax, afforestation cost and industrial oxygen production value of gas regulation services, studies have shown that gas regulation has a significant seasonal changes in flux. The average daily CO2 uptake of the plantations in Qianyanzhou and Changbai Mountains was 82.00 kg · hm2 · d-1 and 59.37 kg · hm-2 · d-1, respectively, and the corresponding O2 fluxes were 59.65 kg · hm- 2 · d-1 and 43.19 kg · hm-2 · d-1. The accumulative process curve of vegetation gas regulation value in both Qianyanzhou and Changbai Mountains mixed forest was S type. The average annual vegetation gas adjustment service value was 14342.69 yuan · hm-2 and 10384.18 yuan · hm-2, respectively. For the net ecosystem gas regulation service, the plantation of Qianyanzhou showed net absorption of CO2 and net release of O2 throughout the year, while the Changbai Mountain mixed forest showed net absorption of CO2 mainly from May to September. The cumulative curve of net ecosystem gas regulation value in Qianyanzhou plantation is S type, while the mixed forest in Changbai Mountain is unimodal. The mean annual net ecosystem services of Qianyanzhou and Changbai Mountains mixed forests were 8470.52 yuan · hm-2 and 5091.98 yuan · hm-2, respectively. Vegetation gas regulation services and net ecosystem gas regulation services occur mainly from May to October. Figure 4 Table 1 reference 21.
