[目的]对红枫湖流域退耕还林项目的碳汇效应进行分析,为贵州省退耕还林的碳汇潜力提供参考依据。[方法]通过对2000~2006年红枫湖流域内退耕还林工程实施情况的调查,对林区内主要树种杉木(Cunninghamia lanceolata)、柳杉(Crypto-meria fortunei)、桃(Amygdalus persica)、李(Prunus salicina)、杏(Armeniaca vulgaris)、喜树(Camptotheca acuminata)和楸树(Catalpa bungei)7种林木的碳汇量及碳汇效应进行计算。在此基础上,估算了红枫湖流域2015年的森林碳汇总量。[结果]2000~2006年,随着时间的变化,森林的中、幼龄林生物蓄积量和碳汇量有上升的趋势,2006年达到1.05×107kg,将发挥越来越大的固碳潜力。在所研究的7种树种中,杉木是研究区内碳汇功能强的树种,预测到2015年,其单位面积碳汇量可以达到106.51t/hm2,其次为柳杉,单位面积碳汇量为99.42t/hm2,杏的碳汇功能最弱,单位面积碳汇量为13.03t/hm2;7种树种的森林碳汇总量为2.35×107kg,平均单位面积碳汇量为26.17t/hm2(c);按305.0元/t的价格计算,可产生7.17×106元的经济效益,按254.1元/t(c)的价格计算,可产生5.91×106元的经济效益。[结论]红枫湖流域退耕还林碳汇效应的经济效益巨大,具有较大的增值空间。
[目的]對紅楓湖流域退耕還林項目的碳彙效應進行分析,為貴州省退耕還林的碳彙潛力提供參攷依據。[方法]通過對2000~2006年紅楓湖流域內退耕還林工程實施情況的調查,對林區內主要樹種杉木(Cunninghamia lanceolata)、柳杉(Crypto-meria fortunei)、桃(Amygdalus persica)、李(Prunus salicina)、杏(Armeniaca vulgaris)、喜樹(Camptotheca acuminata)和楸樹(Catalpa bungei)7種林木的碳彙量及碳彙效應進行計算。在此基礎上,估算瞭紅楓湖流域2015年的森林碳彙總量。[結果]2000~2006年,隨著時間的變化,森林的中、幼齡林生物蓄積量和碳彙量有上升的趨勢,2006年達到1.05×107kg,將髮揮越來越大的固碳潛力。在所研究的7種樹種中,杉木是研究區內碳彙功能彊的樹種,預測到2015年,其單位麵積碳彙量可以達到106.51t/hm2,其次為柳杉,單位麵積碳彙量為99.42t/hm2,杏的碳彙功能最弱,單位麵積碳彙量為13.03t/hm2;7種樹種的森林碳彙總量為2.35×107kg,平均單位麵積碳彙量為26.17t/hm2(c);按305.0元/t的價格計算,可產生7.17×106元的經濟效益,按254.1元/t(c)的價格計算,可產生5.91×106元的經濟效益。[結論]紅楓湖流域退耕還林碳彙效應的經濟效益巨大,具有較大的增值空間。

[Objective]Study on carbon sink effects in Conversion of Farmland to Forest Project in Hongfenghu drainage basin in order to provide evidences for assessing carbon sink potential of conversion of farmland to forest in Guizhou Province.[Method]By investigating the implement of Conversion of Farmland to Forest Project in Hongfenghu drainage basin from 2000 to 2006,the carbon sink amount and effect of seven main tree species in the foreat region like Cunninghamia lanceolata,Cryptomeria fortunei,Amygdalus persica,Prunus salicina,Armeniaca vulgaris,Camptotheca acuminate and Catalpa bungei were calculated,based on which the amount of forest carbon sinks in Hongfenghu drainage basin in 2015 was estimated.[Result]Biomass storage and carbon sink amount in middle and young aged forests were increasing over time from 2000 to 2006,which reached 1.05×107 kg by 2006 and would engage more and more potential.Cunninghamia lanceolata has the superior carbon sink capacity in the seven tree species in the research region,of which the amount of carbon sink per unit area will be 106.51 t/hm2 by 2015,followed by Cryptomeria fortunei with the amount of carbon sink per unit area by 99.42 t/hm2.Armeniaca vulgaris has the weakest carbon sink capacity of all the seven species with the amount of 13.03 t/hm2.The total amount of carbon sink in seven tree species was 2.35×107 kg,while the average amount of carbon sink per unit area was 26.17 t/hm2,which could produced economic benefit of 7.17×106 yuan calculated on the price of 305.0 yuan/t or 5.91×106 yuan calculated on the price of 254.1 yuan/t.[Conclusion]Economic benefits of carbon sink effects of Conversion of Farmland to Forest Project in Hongfenghu drainage basin were great with huge appreciation potential.
