| 摘 要： | 退耕还林工程作为中国重要的植被恢复工程，其碳汇能力巨大。基于河南省退耕还林实施期间河南省森林资源清查数据（1998-2003年，2003-2008年，2008-2013年），利用生物量转换因子连续函数法，估算河南省森林及人工林的碳储量，同时利用2000-2012年河南省退耕还林工程逐年造林树种和面积，估算退耕还林所种树木的碳储量。结果表明:河南省森林面积、蓄积、碳储量和碳密度分别从1998年的149.77×104 hm2，5 258.50×104 m3，30.49 Tg和20.36 Mg·hm-2增加到2013年的305.36×104 hm2，17 094.56×104 m3，91.02 Tg和29.81 Mg·hm-2，其中人工林面积、碳储量、碳密度增幅较大。人工林碳储量占林分总碳储量的比例由1998年的29.26%提高到2013年的58.46%。人工林在河南省森林碳汇中发挥着越来越重要的作用，是河南省森林碳汇的主要贡献者，这主要归因于退耕还林工程的实施引起人工林碳储量的增加。2003，2008和2013年退耕还林工程碳储量分别占森林总碳储量的1.58%，15.40%和30.95%。河南省实施退耕还林工程具有较大的碳汇能力。

| Abstract: | The Grain for Green Program (GGP), an important ecological restoration project in China, has great carbon sequestration capacity. To estimate the carbon storage of Henan Province's forests, based on forest inventory data (1998-2003, 2003-2008, and 2008-2013) in Henan Province, as GGP was being implemented, carbon storage was estimated using the continuous biomass expansion factor (BEF) method. Meanwhile, the planted area for different tree species under the GGP in Henan Province from 2000-2012 was compiled using empirical growth equations to estimate the carbon stock in living tree biomass. Results showed that from 1998 to 2013 in Henan Province, increases were found for forest area from 149.77×104 hm2 to 305.36×104 hm2, volume 5 258.50×104 m3 to 17 094.56×104 m3, carbon storage 30.49 Tg to 91.02 Tg, and carbon density 20.36 Mg·hm-2 to 29.81 Mg·hm-2. Plantation areas, carbon storage, and carbon density greatly increased as the proportion of carbon storage in plantation increased from 29.26% in 1998 to 58.46% in 2013. For the percent of carbon storage from total forest carbon, GGP accounted for 1.58% in 2003, 15.40% in 2008, and 30.95% in 2013. Thus, plantation played an increasingly important role in forest carbon sequestration and were a major contributor to forest carbon sink in Henan Province which was mainly attributed to implementation of the GGP. |
