chinois. 利用2010―2011年在浙江省中部地区调查的517块公益林固定小班监测数据,推算不同群落类型生物量,估算公益林植被碳储量与碳密度,并建立碳密度模型。结果表明：浙江中部地区公益林的生物量为99.30t・hm-2,现存总生物量16430.40万t,植被碳密度平均为49.59tC・hm-2,总碳储量为8205.59万tC;浙江中部地区公益林植被碳密度受林龄与林分密度的影响显著,基于林龄、林分密度两因子拟合了公益林植被碳密度预测模型Cb=aA＋bD＋c,为提高公益林固碳能力的经营管理提供科学依据。

Using the monitoring data from 517 public service forest plots in the central area of Zhejiang Province in 2010-2011, the carbon storage and carbon density of the public service forest were evaluated based on the calculated biomass of different communities. The results showed that the average biomass of the public service forest was 99.30 t・hm-2, the present total biomass was 16 430.40× 104 t, the average carbon density was 49.59 t C・hm-2, and the total carbon storage was 8 205.59×104 t C in central Zhejiang. The analysis also demonstrated that the carbon density was significantly affected by stand age and density. Finally, this study established a model, Cb=aA＋bD＋c ,which was composed by stand age and density to estimate the carbon density of the public service forest in central Zhejiang for improving the public welfare forest carbon sequestration ability.
