摘要

[目的

]

研究不同造林模式的碳储量

为区域碳汇森林的营建提供理论依据。[方法

]

以江苏省徐州市石灰岩山地分布普遍的6种植被恢复模式为研究对象

对其碳储量及其分配格局进行了计算。[结果

]

6种植被恢复模式总碳储量的变化范围在28.379~46.561 t/hm

之间

表现为侧柏(Platyclatdus orientalis)×梧桐(Firmiana simplex) > 侧柏×女贞(Ligustrum lucidum) > 侧柏×枫香(Liquidambar formosana) > 侧柏 > 侧柏×栾树(Koelreuteria paniculata) > 侧柏×黄栌(Cotinus coggygria)。土壤碳储量占总碳储量的54.333%~78.290%。植被碳储量占总碳储量的20.213%~44.414%。枯落物碳储量占总碳储量的0.582%~3.897%。[结论

]

土壤碳储量是不同植被恢复模式总碳储量的主体。保护石灰岩山地现有土层

防治水土流失及频繁的人为扰动对于维持土壤碳储量具有重要作用。加强对侧柏的养护管理

配置适宜的阔叶树种可以有效地增加植被的固碳潜力。

Abstract

[Objective] To investigate the carbon storage of different forest restoration patterns in order to provide theoretical basis for the construction of regional forest carbon sinks. [Methods] The storage and distribution was calculated based on different forest restoration patterns that widely distributed in limestone mountains of Xuzhou City. [Results] The carbon storage of different forest restoration patterns was in the range of 28.379~46.561 t/hm2

followed a sequence of Platyclatdus orientalis×Firmiana simplex > P. orientalis×Ligustrum lucidum > P. orientalis×Liquidambar formosana > P. orientalis > P. orientalis×Koelreuteria paniculata > P. orientalis×Cotinus coggygria. The carbon storage of soil occupied 54.333%~78.290% of the total carbon storage. The carbon storage of vegetation occupied 20.213%~44.414% of the total carbon storage

and the carbon storage of litter only occupied 0.582%~3.897% in total carbon storage. [Conclusion] Soil carbon storage is an important component of the total carbon storage. It is an effective way to maintain soil carbon storage by protecting surface soil

controlling soil and water losses

and reducing artificial disturbance on limestone mountains. Furthermore

strengthening maintenance for Platyclatdus orientalis and selecting the suitable broadleaved tree species can effectively increase the carbon sequestration potential.
