摘要
为贵州马尾松林的可持续经营及其采伐方案的编制提供科学依据,利用2006年和2015年贵州省马尾松林资源二类调查数据,依据马尾松蓄积量与生物量关系,结合支付意愿法,估算不同时期贵州马尾松林的碳储量和固碳经济价值。结果表明:贵州省马尾松林碳储量从2006年的2554.56万tC增至2015年的3603.56万tC,净增加1049.00万tC,年均增长116.56万tC;固碳经济价值从2006年的44.45亿元增至2015年的62.70亿元,提高41.06%;从不同龄林看,2006年和2015年,以中龄林和成熟林最高,分别为20.36亿元和25.65亿元,均以过熟林最低,分别为0.11亿元和1.21亿元;幼龄林和中龄林固碳经济价值2015年较2006年分别降低65.08%和9.63%;近熟林、成熟林和过熟林固碳经济价值2015年是2006年的2.95倍、6.22倍和11.00倍。贵州马尾松林固碳能力随着时间推移而逐渐提高,森林质量向良好方向发展。
In order to provide a scientific basis for the sustainable management of Pinus massoniana forest and the preparation of its cutting scheme,the carbon storage and carbon fixation economic value of P.massoniana forest in Guizhou Province in different periods were estimated by using the secondary survey data of P.massoniana forest resources in Guizhou in 2006 and 2015,based on the relationship between P.massonianavolume and biomass,and combining with the willingness to pay method.Results:The carbon storage of P.massonianaforest increased from 25.5456 million ton in 2006 to 36.0356 million ton in 2015,the economic value of carbon sequestration increased by 41.06%from 4.445 billion Yuan in2006 to 6.270 billion Yuan in 2015.From the perspective of different age forests,the middle-aged forest and mature forest were the highest,which were 2.036 billion Yuan and 2.565 billion Yuan respectively,and the over mature forest was the lowest,with 11 million Yuan and 121 Million yuan respectively;The economic value of carbon sequestration of young forest and middle-aged forest in 2015 decreased by65.08%and 9.63%compared with 2006;The economic value of carbon sequestration of near mature forest,mature forest and over mature forest in 2015 is 2.95 times,6.22 times and 11.00 times respectively compared with 2006.The carbon sequestration capacity of P.massoniana forest in Guizhou gradually improved with time,and the forest quality was developing in a good direction.
