Forest is the leading sink of carbon on the earth, while the forest resources of Heilongjiang Province take an important position in China. Based on the national forest inventory data from 1973 to 2003, the carbon storage of forests in Heilongjiang Province was estimated by the linear relationship between stand biomass and volume. The results showed that the total carbon storage of forests in 1973-1976, 1977-1981, 1985-1988, 1989-1993, 1994-1998 and 1999-2003 was 7.916 x 10(8), 5.413 x 10(8), 5.661 x 10(8), 5.880 x 10(8), 6.216 x 10(8) and 6.011 x 10(8) t, respectively, with an increasing trend since 1977, indicating that the forests in this Province played a role as a sink of atmospheric carbon dioxide, and this functioning was strengthened during the last 20 years. If the current forest is managed well, it would become a huge potential carbon sink in the future.
森林是地球上主要的碳汇，而黑龙江省的森林资源在中国占有重要地位。基于1973年至2003年的全国森林资源清查数据，利用林分生物量与蓄积量的线性关系估算了黑龙江省森林的碳储量。结果表明，1973 - 1976年、1977 - 1981年、1985 - 1988年、1989 - 1993年、1994 - 1998年和1999 - 2003年森林的总碳储量分别为7.916×10⁸、5.413×10⁸、5.661×10⁸、5.880×10⁸、6.216×10⁸和6.011×10⁸吨，自1977年以来呈增加趋势，表明该省森林起到了大气二氧化碳汇的作用，且在过去20年中这种作用得到加强。如果当前森林得到良好管理，未来它将成为一个巨大的潜在碳汇。
