研究冀北山地常见的2种灌丛(榛子灌丛、土庄绣线菊灌丛)的碳密度特征。结果表明：土庄绣线菊灌丛各个组分的碳密度及总碳密度都明显低于榛子灌丛，土庄绣线菊灌丛的生物碳密度、凋落物碳密度、土壤碳密度和总碳密度分别为5.91，0.23，54.31和60.44 t·hm -2，榛子灌丛的生物碳密度、凋落物碳密度、土壤碳密度和总碳密度分别为12.81，1.38，141.08和155.27 t·hm -2；土庄绣线菊灌丛的生物碳密度明显低于中国主要6种灌丛的平均值(10.88 t·hm -2)，而榛子灌丛则高于该平均值；绣线菊灌丛的总碳密度也明显低于该地区的华北落叶松林、山杨林、白桦林、蒙古栎林和油松林，榛子灌丛的总碳密度则低于落叶松林、山杨林和白桦林，但高于油松林和蒙古栎林。由此得出结论：2种灌丛之间的碳密度存在较大差异，未受到明显干扰且立地条件较好的灌丛具有较高的碳密度；在区域植被碳密度的评估中应将灌丛纳入评估范围；应采取有效措施诱导该地区的灌丛向乔木林进行演替，以提高碳截存能力；灌丛的碳截存是乔木林碳汇作用在空间和时间上的补充。

The carbon density characteristics of two common types of shrubs ( including Spiraea pubescens shrub and Corylus heterophylla shrub ) were studied in the paper,which are distributed in northern mountain region of Hebei province. The results showed that Spiraea pubescens shrub was higher than Corylus heterophylla shrub in both the carbon density of every parts and total carbon density. The biological carbon density,litter carbon density,soil organ carbon density and total carbon density of Spiraea pubescens shrub were 5. 91 ,0. 23 ,54. 31 and 60. 44 t·hm -2 ,and those of Corylus heterophylla shrub were 12. 81 ,1. 38 ,141. 08 and 155. 27 t·hm -2 . The biological carbon density of Spiraea pubescens shrub was lower than the average carbon density of shrub communities of China which was 10. 88 t·hm -2 ,and that of Corylus heterophylla shrub was higher than that. The total carbon density of Spiraea pubescens shrub was lower than that of Larix gmelinii forest,Populus davidiana forest,Betula platyphylla forest,Quercus mongolica forest and Pinus tabulaeformis forest,and the total carbon density was lower than that of Larix gmelinii forest,Populus davidiana forest, Betula platyphylla forest,and higher than that of Quercus mongolica forest and Pinus tabulaeformis forest. It was concluded that there is significant difference among various shrubs,and there is a bigger carbon density in the shrubs under better site conditions and free of disturbance for long time and the carbon density of shrubs should be considered when the carbon density is evaluated in regional scale, moreover, in order to enhance carbon sequestration of vegetation, some measurements should be carried out to lead a succession from shrubs to forests. Shrubs might be regarded as complementary for forests in carbon sequestration in temporal and spatial aspects.
