中国森林碳汇服务价值评价

Value Evaluation of Forest Carbon Sinks Services in China

对森林碳汇服务价值核算可促进碳汇市场的快速发展,还能更好地了解森林碳汇对气候变化与经济发展的影响。结合森林碳汇的研究背景,根据中国森林生态系统特点与最新的森林资源清查数据,利用蓄积量法对2009-2013年的森林碳汇进行计量研究。结果表明:2009-2013年中国的天然林和人工林碳储量均呈上升趋势,其中人工林的碳储量增速要高于天然林;森林碳汇价格下降致使森林碳汇价值整体下降,年均减少0.13%,下降的主要原因是天然林碳汇价值降低,年均减少0.58%,但人工林碳汇价值呈增加态势,年均增加2.81%,这与森林碳汇实物量的计量结果相同。最后指出目前中国碳交易市场情况不容乐观,碳汇市场除碳交易形式外,还应构建多样化的碳汇交易渠道;提升社会公众对森林碳汇价值的认知度和继续加强林业建设,找到一种既经济、操作简单又可确保精度的森林碳汇计量方法意义重大。

The measurement of forest carbon sink can largely promote the rapid development of the carbon market, and can also gain a better understanding of the forest carbon sinks to climate change and economic development influence. Using the volume measurement combination of forest carbon sequestration research background, A quantitative research has been carried out regarding the forest carbon sinks from 2009 to 2013 according to China＇s forest ecosystem characteristics and the latest forest resources inventory data. The results showed that China＇s natural forest and plantation carbon were on the rise from 2009 to 2013. The plantation carbon reserves grow faster than natural forests; forest carbon sink value wholly decreases due to the price of forest carbon sinks, annually averaged by 0.13%. The lowering value of natural forest carbon sinks, the annually averaged by 0.58%, mainly attributes to the decrease. But the artificial forest carbon sink value increases by 2.81% annually; this was the same as measuring the conclusion of converting forest carbon sink. Finally, it points out that China＇s current carbon market situation is not optimistic, and carbon sequestration in addition to the form of carbon trading market, we should also build a variety of carbon sink trade channels and should raise the public awareness of forest carbon sinks value and continue to strengthen the construction of forestry. It was of great significance to find a kind of forest carbon sinks measurement method of economy, simple operation and high precision.
