摘要:
 基于森林资源二类调查数据,运用生物量转换因子法和单位面积平均生物量法,估算西藏自治区扎囊县森林生物量,再乘以含碳系数估算森林碳储量。根据生物群落演替的顶级理论和空间代替时间法,以成熟林碳储量作为森林生物量碳容量参照,应用森林生物量碳容量与当前( 或某一年) 森林碳储量的差值估算森林固碳潜力。结果表明,扎囊县森林植被碳储量为768 751.91 t。灌木林是青藏高原的原生植被,碳储量占森林碳储量的84%,发挥着重要的固碳作用。扎囊县森林资源以发挥生态防护功能为主要目的,有利于森林自然生长积累碳储量,防护林面积和碳储量占森林面积和碳储量比例均高达99%。乔木林碳储量按起源以人工林为主,占91%;按树种以柳树和杨树为主,占90%;在龄组方面,中龄林、近熟林和成熟林碳储量较大,占88%。随着龄组增大,从幼龄林、中龄林、近熟林、成熟林到过熟林,碳密度依次增大,从1.17 t/hm2到55.67 t/hm2。乔木幼龄林、中龄林和近熟林在乔木林面积中占88%,但是碳密度远低于乔木成熟林的平均碳密度40.28 t/hm2。随着乔木林从幼龄林逐步成长为成熟林,碳储量将显著增大。乔木林固碳潜力为251 782.90 t,是乔木林碳储量的2.21倍。宜林地、无立木林地、未成林造林地和苗圃地固碳潜力与面积大小正相关,固碳潜力为365 947.81 t。相应的措施可以进一步提高森林碳汇:封山(沙)育林等措施促进灌木林资源发展,稳定并提高灌木林面积和覆盖度;全面提升森林经营管理水平,提高森林资源质量;继续推进重点林业工程建设,因地制宜开展人工造林和封山育林,提升森林资源培育水平,确保人工造林成效。
Abstract:
 Based on the second type inventory of forest resources,forest biomass in Zha’nang county,Tibet Autonomous Region was estimated by using the methods of biomass expansion factor and average biomass per unit area,from which forest carbon storage was calculated by further multiplying carbon coefficient.According to the top theory of biological community succession and space-for-time substitution method,and taking carbon storage of mature forest as a reference of carbon carrying capacity,potential carbon sequestration was estimated based on the difference between carbon carrying capacity and carbon storage in current or a certain year.The results showed that forest carbon storage in Zha’nang county was 768 751.91 t.Shrub forests were the native vegetation in the region,which played an important role in carbon storage,and accounting for 84% of the total.For the purpose of ecological protection,forest resources growing naturally in Zha’nang county were beneficial to the accumulation of carbon storage.Percentages of both protection forest area and carbon storage accounted 99% of the total.The carbon storage of arbor forest was mainly comprised of planted forests with the proportion of 91%.From the view of forest types,Salix sp.and Populus sp.were the main arbor species with the proportion of 90%.From the view of forest age,middle-aged,pre-mature,and mature forests demonstrated high carbon storage (accounting for 88%).Carbon density increased with the forest age,ranged from1.17 t/hm2 to 55.67 t/hm2.The carbon densities of young forest,middle-aged forest and pre-mature forest were far below that of mature forest.As young forest developed into mature forest,carbon storage increased significantly.The potential carbon sequestration of arbor forest was 251 782.90 t,2.21 times the carbon storage of arbor forest.The potential carbon sequestrations of suitable land for forest,unstocked forest land,unforested land and nursery were 365 947.81 t,positively correlated to the area.Taking relevant measures could further promote forest carbon sequestration:to conduct closing hillside project to develop shrub forest,to stabilize and increase the area and coverage of shrub forest; to promote the level of forest management and to improve the quality of forest resources; to sustainably carry out the key forestry projects and to further implement the policy of afforestation and closing the land for reforestation,to promote the level of forest resource cultivation and to ensure artificial afforestation effect.
