| 中文摘要 | 黄土高原碳储量及碳密度的准确估计对全球碳失汇的研究有重要贡献。通过研究黄土高原子午岭林区辽东栎天然次生林不同组分的碳含量及碳储量,为准确估算黄土高原森林植被碳储量及碳密度提供依据。结果表明:辽东栎中幼林、近熟林和成熟林乔木干、皮、枝、叶、根的碳含量分别为44.16%～47.01%、44.09%～45.50%、43.17%～46.25%、44.67%～46.36%和38.93%～41.10%;灌木层叶、枝、根的碳含量分别为44.39%～46.26%、30.19%～48.95%和28.06%～40.13%;草本层地上、地下的碳含量分别为28.38%～45.27%和24.53%～46.06%;枯落物层的碳含量为32.10%～32.90%。3个林龄段乔木层碳储量依次为32.78、35.51和43.79t·hm-2,灌木层碳储量依次为3.31和1.72、0.87t·hm-2,草本层碳储量为0.32、0.77和0.64t·hm-2,枯落物层碳储量为6.03、3.14和4.37t·hm-2。在3个林龄段,辽东栎群落的碳储量依次为42.45、41.41和49.67t·hm-2。由此可知,在子午岭区,辽. |
| 英文摘要 | To accurately estimate the carbon storage and carbon density in Loess Plateau is of significance to understand the global carbon sink-source balance． In this study，an investigation was made on the carbon distribution in different components of natural Querus wutaishanica ( syn． Q． liaotungensis) forest in Ziwuling of Loess Plateau hinterland，aimed to provide basis for accurately estimate the carbon concentration and carbon storage of forest vegetation in Loess Plateau． In the young and medium age，near-mature，and matured Q． wutaishanica forests，the carbon concentration of stem，bark，branch，leaf，and root was 44． 16% － 47． 01%，44． 09% － 45． 50%， 43． 17% － 46． 25%，44． 67% － 46． 36%，and 38． 93% － 41． 10%，respectively． In shrub layer， the carbon concentration of leaf，branch，and root was 46． 26% － 44． 39%，30． 19% － 48． 95%，and 28． 06% － 40． 13%; in herb layer，the carbon concentration of above- and belowground parts was 28． 38% － 45． 27% and 24． 53% － 46． 06%，respectively; and in litter layer， the carbon concentration was 32． 10% － 32． 90%． The carbon storage of tree layer in the young and medium age，near-mature，and matured Q． wutaishanica forests was 32． 78，35． 51，and 43． 79 t·hm － 2，and that of shrub layer，herb layer，and litter layer was 3． 31，1． 72 and 0． 87 t·hm － 2，0． 32，0． 77 and 0． 64 t·hm － 2，and 6． 03，3． 14 and 4． 37 t·hm － 2，respectively． The total carbon storage of the three age forests was 42． 45，41． 41，and 49． 67 t·hm － 2，respectively． All the results indicated that in the Ziwuling of Loess Plateau hinterland，matured Q． wutaishanica forest had the greatest carbon storage，and in the three age natural Q． wutaishanica forests，the carbon storage was in the order of tree layer ＞ litter layer ＞ shrub layer ＞ herb layer． It was considered that in Ziwuling of Loess Plateau hinterland，the carbon storage of matured forest had the greatest contribution to the carbon storage of natural Q． wutaishanica forest，which should be paid more attention in the estimation of |
