Abstract:

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.
