摘　　要：利用第七次和第八次全国森林资源连续清查海南省乔木人工林样地数据,估算人工林碳储量和分树种、龄组、林种的碳储量分布情况,以及连续清查间隔期内的碳汇量。结果表明,截至2013年,海南省人工乔木林碳储量为878.4万t;近成过熟林储存了大量的有机碳,同时鉴于中幼龄林所占面积比例超过60%,这部分人工林有望在未来发挥良好的碳汇功能;2008―2013年人工林碳汇量为41.3万t/a,可抵消7.38%的工业碳排放份额,人工林生态系统碳汇可以抵消工业碳排放份额的11.7%~16.6%。Using data of the seventh and eighth national forest resources continuous inventory, the paper esti- mated carbon storage of plantations and the distribution of carbon stock in different tree species, age groups and forest species, carbon sink during continuous inventory intervals was estimated simultaneously. The results showed that by 2013, the carbon storage of artificial trees in Hainan was 8 784 000 t. Nearly mature, mature and too mature forest storaged a large number of organic carbon, and in view of the proportion of young forest was more than 60 % , this part of plantation was expected to play continuous carbon sink function in the future. Carbon sink of artificial forest from 2008 to 2013 was 413 Gg/a, offsetting 7.38 percent of industrial carbon footprint. Carbon sink of plantation ecosystem can offset industrial carbon emissions by 11.7 percent to 16.6 percent. The paper provided basic data for increasing forest carbon stocks and carbon sequestration potential through forestry practices such as afforestation and forest resource management.
