湖州市省重点公益林生物量和固碳能力研究

Biomass and Carbon Storage of Key Ecological Forest in Huzhou

在综述国内外森林生物量研究的基础上,应用相容性生物量模型对湖州市省重点公益林生物量特征进行了分析。结果表明:2008年湖州市省重点公益林生物量总量为583.46万t,年增长率7.59%。现有森林的生物量中阔叶林221.07万t,占37.89%;毛竹135.28万t,占23.19%;松林121.35万t,占20.80%;针阔混交林74.77万t,占12.82%;杂竹林14.42万t,占2.47%;杉木林12.77万t,占2.19%;灌木3.78万t,占0.64%。进一步计量测算湖州市重点公益林固碳价值为10.211 7亿元,释放氧气价值为6.806 7亿元,合计为17.018 4亿元。

Biomass of key ecological forest was analyzed with compatible biomass model in Huzhou, Zhejiang province. Results showed that in 2008 the gross biomass of key ecological forest topped to 5 834 600 t in Huzhou, and the annual growth rate was 7.59%. The biomass of broad-lcaved forest had 2 2 10 700 t, accounting for 37.89% of the total one, that of PhyIlostachys hereocycla vat. pubencens forest was l 352 800 t, about 23.19%, that of pine forest was 1 213 500 t, about 20.80%, that of mixed forest was 747 700 t, about 12.82%, that of bamboo forest was 144 200 t, about 2.47%, that of Chinese fir forest was 127 700 t, about 2.19%, that of shrubs was 37 800 t, about 0.64%. The total cvcaluated value of key ecological forest was 17.0184×10^8 yuan RMB, including both the carbon sequestration value of 10.2117× 10^8 yuan RMB, and the oxygen releasing value 6.8067× 10^8 yuan RMB.
