摘要
采用样方调查和室内分析方法,研究了贵州喀斯特地区5种人工林配置模式碳储量的异质性,为人工林群落碳循环和碳平衡机制的研究提供参考。结果表明:(1)乔木树种不同器官中的碳储量存在差异,除构树外,均表现为枝的碳储量最低,国槐、白蜡、构树根的碳储量最高,女贞和任豆树干碳储量最高;(2)灌木树种除模式4多花木兰外,其余均表现为根的碳储量最高;(3)藤本树种各器官碳储量存在差异,模式1金银花和模式2金银花表现为枝的碳储量最高,其余3种模式均以叶的碳储量为最高;(4)各模式草本碳储量除对照外,均表现为地上部>地下部,且差异显著。
The heterogeneity of carbon stocks for five forest recovery modes in karst area of Guizhou was studied using methods of quadrat investigation and laboratory analysis, which provided reference for the study on carbon cycle and carbon balance mechanism of plantations. The results showed that ： （ 1 ） Carbon stocks in different organs of tree were different, carbon stocks of branches in the other four kinds of tree was the lowest except Broussonetia papyrifera, carbon stocks of root in Sophora japonica, Fraxinus chinensis and Broussonetia papyrifera were the highest, while the carbon stocks of trunk in Ligustrum lucidum and Zenia insignis were the highest. （2） Carbon stocks of root in the other four kinds of bushes were the highest except Magnolia multiflora ; （ 3 ） Carbon stocks in different organs of fuji- moto were different. Carbon stocks of branch in mode 1 and mode 2 were the highest, while, carbon stocks of leaf in the other three modes were the highest ; （4） Carbon stocks of herbaceous were aboveground 〉 underground in all modes except the control, and the difference was significant.
