摘  要:
利用湖南2014年森林资源清查样地资料,采用系统抽样理论,综合运用回归模型方法对长株潭地区绿地植被(乔、灌、草)碳贮量与碳密度进行了研究,为建立碳汇计量监测体系提供可靠数据,以期为科学评价区域植被在碳平衡中的作用提供依据。研究结果表明:长株潭地区植被总碳贮量为47.31 Tg(1Tg=10~(12)g),森林植被碳贮量为39.22 Tg,占植被总量的89.73%,其中乔木层碳贮量占71.7%、灌木层碳贮量占22.8%、草本层碳贮量占5.5%;植被平均碳密度为16.9 t/hm~2,森林植被平均碳密度为29.53 t/hm~2;自然地理因子与植被碳密度具有明显相关性。

摘  要:
In order to provide reliable data for the measurement and monitoring system of carbon sink,and evaluate the role of vegetation in the carbon balance. In this paper,based on original data of Hunan forest continuous inventory in 2014,the vegetation carbon storage and carbon density of Changsha-Zhuzhou-Xiangtan urban agglomeration were studied. The results showed that: the total vegetation carbon storage was 47. 31 Tg,forest vegetation carbon storage was 39. 22 Tg,account for 89. 73 %; In forest vegetation storage,the carbon storage of tree layer,shrub layer,herb layer account were 71. 7 % and 22. 8 % and 5. 5 % respectively; the average vegetation carbon density was 16. 9 t / hm~2,the average carbon density of forest vegetation was29. 53 t / hm~2. Natural geographical factors and vegetation carbon density had a significant correlation.
