摘要/Abstract

摘要： 通过建立不同优势树种生物量与蓄积量之间的回归模型,以树种含碳率作为生物量转换为碳储量的系数,利用2007年河南省森林资源规划设计调查资料,对南阳市南水北调中线工程渠首水源地乔木林生物量和碳储量进行推算。结果表明:水源区总生物量为2 212.25万t,总碳储量为1 103.35万t;阔叶林碳储量占乔木林碳储量的96.5%,其中栎类最多占82.1%;幼龄林碳储量占用材树种的90.9%;研究区乔木林平均碳密度为22.08t/hm²。研究可为当地生态环境改造提供借鉴参考依据。

Abstract: In this study,we used regression equation between biomass of various tree species and volume,took carbon-included reat in different tree species as the transferring coefficient from biomass to carbon stock.The arbor biomass and carbon storage in Nnanyang Water Source area of the middle section of the South to North Water Transfer Project were estimated based on original Forest Resource Inventory Data of Henan Province in 2007.The results showed that the total arbor biomass is 2212.25×10⁴ t,the total carbon storage is 1103.35×10⁴t.Carbon storage of the broad leaf forests is more that 96.5% of total arbor forests in this area and that of deciduous oaks is the most,acounting for 82.1%,the carbon storage of young aged forests is 916.6×10⁴t,accounts for 83.3% of the total timber tree species biomass carbon storage in the areas;The average carbon density of arbor forest is 22.08t/hm².

Key words: arbor forest, biomass, biomass expansion factor, carbon storage, carbon density
