| 为将植被的固碳增汇效应纳入到贵州喀斯特山区植被恢复与重建工程中，研究了贵州典型喀斯
特峰丛洼地环境下5 种植物配置模式的碳储量、空间分布特征及其固碳效益。结果表明：不同配置模式植被
各层碳储增量表现为草本层＞藤本层＞灌木层＞乔木层，其中草本层碳储量增量占植被层碳储量比重变化范
围为36.56%~78.07%，在植被层中居主导地位；不同配置模式土壤层碳储量与对照相比没有明显变化，女
贞林、国槐林、任豆林和白蜡林较对照有略微增加，而构树林则稍有下降，且土壤层的碳储量在各配置模
式碳储量中占据主导地位；研究区实施植被恢复后各配置模式碳储量均有所升高，女贞林、国槐林、任
豆林、白蜡林和构树林的碳储量分别增加了0.579、1.813、3.254、1.227、1.349 t/hm2，固碳效益表现为任豆林

| 英文摘要: |
| In order to integrate increasing carbon sequestration of plants into vegetation restoration and
reconstruction project in Guizhou karst areas，the carbon storage，spatial distribution characteristics and
carbon sequestration benefits of 5 kinds of configuration modes were studied in depression between karst
hills. The results showed that，carbon storage increment of each layer plants in different configuration modes
performanced as herbaceous layer ＞ fujimoto layer ＞ shrub layer ＞ tree layer，the proportion of carbon storage
of herbaceous layer in total carbon storage varied from 36.56% to 78.07%，which was dominant in vegetation
layer. Carbon storage of soil had no significant change compared with the control group，soil carbon storage of
Ligustrum lucidum，Sophora japonica，Zenia insignis and Fraxinus chinensis increased slightly，but decreaced
for Broussonetia papyrifera，and carbon storage of soil was dominant in the total carbon storage of different
configuration modes. the carbon storage of each configuration mode were all increaced after the implementation
of vegetation restoration in research areas，the carbon storage of L. lucidum，S. japonica，Z. insignis，
F. chinensis and B. papyrifera increaced by 0.579
t/hm2、1.813 t/hm2、3.254 t/hm2、1.227 t/hm2、1.349
t/hm2 respectively，carbon sequestration benefits
performanced as Z. insignis（848.97 Yuan/hm2）
＞ S. japonica（473.01 Yuan/hm2）＞ B. papyrifera
（351.95￥/hm2）＞ F. chinensis（320.12 Yuan/hm2）
＞ L. lucidum（151.06 Yuan/hm2）. |
