| 摘 要： | 本文以广东三岭山森林公园的马尾松、尾叶桉、大叶相思人工林为研究对象，研究对比它们的碳储量和碳汇经济价值，为评价广东的3个优势造林树种的碳汇能力及为广东的造林选择提供依据。结果表明：3种人工林树种单位碳储量由大到小排列次序为：尾叶桉(166.89 t·hm-2)＞大叶相思(128.72 t·hm-2)＞马尾松(70.12 t·hm-2)。3种人工林平均碳汇经济价值按大小排列次序为：尾叶桉(45611.04元·hm-2)＞大叶相思(35179.18元·hm-2)＞马尾松(19163.80元·hm-2)。尾叶桉是这3种人工林中碳储量的主要部分，对广东三岭森林公园发挥着巨大的碳汇功能并具有强大的碳汇经济价值。因此，可以考虑在广东省碳汇造林时选择尾叶桉种植。

The Evaluation of Carbon Sink Function and Economic Value of Plantations in Guangdong Three Ridge Hill Forest Park |
| |
| Abstract: | Pinus massoiana, Eucalyptus urophylla and Acacia auriculiformis plantations in Guangdong Three Ridge Hill Forest Park were studied to evaluate carbon sink capacity of three predominant forestation trees used in Guangdong, and provide the basis for further forestation efforts in this province. The results showed that carbon storage was highest in E. urophylla plantations (166.89 t·hm-2), followed by Acacia auriculiformis plantations (128.72 t·hm-2) whilst Pinus massoniana plantations (70.12 t·hm-2) had the lowest carbon storage of the three species. The average economic values of carbon sinks of stands of the three species order by decreasing value were:Eucalyptus urophylla plantations (45 611.04 CNY·hm-2) > Acacia auriculiformis plantations (35 179.18 CNY·hm-2) > Pinus massoniana plantations (19 163.80 CNY·hm-2). Carbon storage provide Eucalyptus urophylla plantations in this part of Guangdong already far exceeds that provided by the other two species, and its plantations function as important carbon sinks providing strong potential economic benefits. |
