摘要：

以清潔發(fā)展機(jī)制（CDM）廣西珠江流域治理再造林項(xiàng)目為例，對(duì)項(xiàng)目及其5種造林模式臨時(shí)核證減排量（temporary certified emission reduction，縮寫為tCER）和長(zhǎng)期核證減排量（long-term certified emission reduction，縮寫為lCER）成本的動(dòng)態(tài)變化進(jìn)行了初步研究。結(jié)果表明：從項(xiàng)目期初到期末，整個(gè)項(xiàng)目及5種造林模式人工林的tCER成本均逐漸降低，其中項(xiàng)目成本由第一承諾期末的40.33 ￥/t CO₂降至最后承諾期末的13.34 ￥/t CO₂；lCER成本先降低后升高，在第一承諾期末均降至最小值，項(xiàng)目成本由第一承諾期末的40.33 ￥/t CO₂增加至最后承諾期末的105.27 ￥/t CO₂；各造林模式tCER和lCER成本均以楓香+杉木、楓香+馬尾松較高，馬尾松+荷木、馬尾松+櫟類較低，桉樹最低；貼現(xiàn)率對(duì)項(xiàng)目tCER和lCER、桉樹tCER、楓香+杉木lCER成本影響均較大，而對(duì)馬尾松+櫟類tCER和lCER成本影響均較小；對(duì)桉樹一個(gè)輪伐期內(nèi)的tCER成本進(jìn)行了敏感性分析，單位面積碳貯量的變化對(duì)其影響較大；考慮木材收益時(shí)，項(xiàng)目期末tCER凈現(xiàn)值為13.11 ￥/t CO₂，從中反映了該CDM項(xiàng)目實(shí)施是可行的。

Abstract:

Based on a case study of facilitating reforestation for Guangxi section of Pearl River watershed, dynamic cost changes in carbon sequestration under the clean development mechanism (CDM) project and the five afforestation models in tCER (temporary certified emission reduction) and lCER (long-term certified emission reduction) were explored. The results show that tCER costs of the project and five models will decrease gradually, and project cost will reduce from 40.33 ￥/t CO₂to 13.34 ￥/t CO₂. The lCER costs will be down to the minimum in the terminal of the first commitment period, and project cost will increase from 40.33 ￥/t CO₂ to 105.27 ￥/t CO₂. The costs of L. formosana plus C. lanceolata and L. formosana plus P. massoniana will be higher than P. massoniana plus S. superba and P. massoniana plus Quercus sp., and Eucalyptus sp. will be the lowest cost. The choice of discount rate will impact on cost of the project, Eucalyptus sp. in tCER and L. formosana plus C. lanceolata in lCER, and it is not obvious to P. massoniana plus Quercus sp. in tCER and lCER. The sensitivity of tCER cost to Eucalyptus sp. were also analyzed. It is found that changes in carbon storage per unit area can affect the tCER cost. The net present value of project tCER will be 13.11 ￥/t CO₂ with timber benefits in the end, thus suggesting that the implement the CDM project is feasible.
