通过在不同区域的银中杨、小黑杨、青山杨、迎春五号杨人工林设置标准地，利用生物量法对这4种林分的碳储量进行了计量研究。结果表明：4种杨树新品种人工林碳储量与生物量成正比，以树干、树枝、树根、树叶的顺序由高到低排列；4种杨树新品种人工林年净固碳量分别为银中杨4．04t 灋hm -2灋a-1、青山杨3．06t 灋hm -2灋a-1、迎春五号杨2．46 t 灋hm -2灋a-1、小黑杨1．98 t 灋hm -2灋a-1。

Sample plots were set in Populus alba× P.berolinensis ,P.simonii× P.nigra,P.pseudo-cathayana × P .deltoides Barry Shan Hai Guan ,P .nigra× P .simonii plantation in different regions .Carbon storage of these four stand were measured by using biomass method .It is found that carbon storage is proportional to biomass of four new varieties of poplar ;the descending order is trunks ,branches ,roots ,leaves .Annual net sequestration of four new varieties of P .alba× P .berolinensis ,P .pseudo-cathayana × P .deltoides Barry Shan Hai Guan ,P .nigra× P .si-monii,P.simonii×P.nigrais4.04t·hm-2·a-1 ,3.06t·hm-2·a-1 ,2.46t·hm-2·a-1 ,1.98t·hm-2·a-1 .
