森林碳汇是指森林利用光合作用吸收大气中的CO2并以生物量的形式贮存在植物体内和土壤中的能力。近年来,随着人口的增长和经济的发展,人类排放温室气体持续增加,导致地球气候不断变暖,而森林所固有的吸收和固定CO2的功能即森林碳汇功能,能够有效地减少大气中的CO2浓度,起到减缓气候变暖的作用。本研究以安徽省宜秀区人工杨树林为研究对象,设置面积为0.24 hm2的样地一块,采取相邻格子法将其区划为20 m×30 m的乔木样方4块。在样方内进行每木检尺,每块样地选取平均标准木一株,供乔木层生物量测定,林分乔木层总生物量按转换系数进行计算。结果表明：研究地林分径级分布集中在18 cm～28 cm之间,林龄为10 a;无论在单木还是林分中,干生物量都占绝对主体地位;研究地10 a生人工杨树林乔木层每公顷碳储量为196.0016 t。

The forest carbon storage refers to its ability to absorb and store CO2 in plants and soil through the photosynthesis.In recent years,with the increasing population and economic development,more and more greenhouse gases have been released.At the same time,the forest carbon sinks,whose intrinsic function is to absorb and store CO2,can effectively reduce the greenhouse gase density to handle climate change.Based on the study object-poplar plantation in Yixiu District of Anhui Province,a land of 0.24 hectare is selected,which is divided into four smaller checked areas of 20 m×30 m.After measuring every poplar tree,one average standard tree is chosen from every stand for measuring the biomass in the arborlayer.Then the total arbor-layer biomass is calculated according to the transform coefficient.The results have shown that the stand diameter mainly ranges from 18 cm to 28 cm with a forest age of 10 years.The dry biomass is dominant both in the individual tree and in the stand and the carbon storage of poplar trees in the arbor layer is 196.0016 tons per hectare.
