摘要：运用生态经济学原理,对广西主要人工林类型在一个完整轮伐期内的固碳成本现值动态变化及其敏感性进行系统分析和比较,并分析不同贴现率对各人工林类型固碳成本的影响,同时结合木材收益分析主要人工林类型固碳成本与净收益,并且将净收益与不考虑木材收益时的固碳成本进行比较。结果表明:主要人工林固碳成本现值均随林龄的增加而降低;各人工林类型在轮伐期末的固碳成本现值以木荷+枫香、杉木、桉树较大,其中,木荷+枫香每吨碳171.8～283.4元,杉木178.3～271.7元,桉树211.0～225.9元;马尾松、柳杉+水杉、木麻黄+檫树较小,其中,马尾松每吨碳133.3～218.9元,柳杉+水杉133.0～205.7元,木麻黄+檫树122.0～159.1元;栎类+青冈最小,每吨碳仅48.9～100.4元;以杉木为例的各项成本的年际波动明显影响所核算的固碳成本;采用较低贴现率与较高贴现率所计算出的各树种轮伐期末固碳成本现值相差较大,贴现率对木荷+枫香轮伐期末固碳成本影响较大,对桉树影响较小;在评价碳汇造林项目实施的可行性方面,固碳成本-净收益分析是非常必要的。
Dynamic changes and sensitivity of present value for carbon-sequestrated cost were systematically analyzed and compared in a complete rotation from main plantation types in Guangxi with ecological economic principles. This study also analyzed impact of different discount rates on carbon-sequestrated cost of various plantation types,calculated the carbon cost-net income of main species plantations with timber benefits,and compared the net income with cost of plantation without timber benefits. The results showed that the present values of carbon-sequestrated cost were decreased with increasing ages of main plantations. Schima superba ＋ Liquidambar formosana, Cunninghamia lanceolata and Eucalyptus spp. had higher present value for carbon cost than others at the end of rotation. It cost $ 171. 8 ～ 283. 4 per ton C for Schima superba ＋ Liquidambar formosana,$ 178. 3 ～ 271. 7 for Cunninghamia lanceolata,$ 211. 0 ～ 225. 9 for Eucalyptus spp. , $ 133. 3 ～ 218. 9 for Pinus massoniana, $ 133. 0 ～ 205. 7 for Cryptomeria fortunei ＋ Metasequoia glyptostoboides, $ 122. 0 ～ 159. 1 for Casuarina equisetifolia ＋ Sassafras tzumu,and $ 48. 9 ～ 100. 4 for Quercus. sp. ＋ Cyclobalanopsis glauca. Annual fluctuations of input costs affected the counted carbon cost in the case of Cunninghamia lanceolata. The calculated present values of cost were obviously different by using a lower discount rate from a higher discount rate at the end of rotation,and the discount rate impacted obviously Schima superba ＋ Liquidambar formosana, however not obviously Eucalyptus spp. at the end of rotation. It was necessary to analyze carbon cost - net income in evaluating the feasibility of carbon project implementation from afforestation.
