摘要
以2013年安仁县"十二五"森林资源调查资料作为依据,运用生物量、蓄积量为依据的生物量转换因子连续函数法,对安仁县9种森林类型的生物量、碳贮量进行了估算。结果表明:安仁县的主要森林类型是杉木、慢生阔叶树、马尾松、中生阔叶树、湿地松、速生阔叶树、桉树组、柏木、杨树,其中杉木是优势树种,林分面积占乔木总面积的40.07%;幼龄林占乔木林面积的51.85%,中龄林占乔木林面积的21.15%,近熟林占乔木林面积的11.35%,成熟林占乔木林面积的7.25%,过熟林占乔木林面积的1.40%;主要树种的生物量、碳贮量分别为1 808 132.55×10~3、904 006.37×10~3 t,碳汇价值为5.8×10^(10)元;林分单位面积生物量、平均碳密度分别为25.37、12.68 t·hm^(-2);几种森林类型单位面积的生物量、碳密度都比全国平均水平低,因此,安仁县的碳汇潜力非常大。
This article based on the data twelve five forest resource survey of Anren county in 2013, using the biomass conversion factors between biomass and volume based on continuous function method 9 tree species of biomass, carbon and carbon storage were estimated of Anren county. Results is concluded that： the main forest types of Anren is Cunninghamia lanceolata, slow-growth broadleaved trees, Pinus massoniana, normal-growing broadleaved trees, Pinus elliottii, fast-growth broadleaved trees, Eucalyptus, Cedar wood, Populus L. The Cunninghamia lanceolata is advantage, the forest stand area accounted for 40.07% of the total area. the young forest age, the mid-maturation forest age, the nearly ripe forest age, the arbor area mature forest, the overripe Lin forest stand area accounted for 51.85%, 21.15%, 11.35%, 7.25%, 1.40% of the total area. The biomass and carbon storage of the main tree in Anren were 1 808 132.55×10^3, 904 006.37×10^3 t; The value of carbon sinks was 5.8×10^10 yuan; the average biomass and the average carbon density are 25.37, 12.68 t·hm^-2; the average forest biomass and the average carbon density of Anren were lower than that of the national level. Therefore, the potential carbon sink of forest is very great in Anren.
