太岳山3种林型碳储量及其空间分配格局
Carbon storage and spatial distribution of natural forest in Taiyue Mountain
摘要
Abstract
Carbon (C) storage and its distribution among aboveground parts, including tree, shrub, herb layers, floor litter, and soils in the depth of 0-20 cm were investigated in Pinustabulaeformis forest(PF),Quercusliaotungesis forest (QF), and PF × QF mixed forest(MF) in Taiyue natural reserve. Results showed that total C stock averaged at 123.01,153.53,132.93 t·hm-2in PF, QF,and MF, respectively, with C stock of aboveground parts accounting for 70.83%, 60.94%, 57.50% of the total. And aboveground C stock most enriched in tree layer,peaking at 65.96%,58.07%,and 54.01% in PF,QF,and MF,respectively. To-tal C stock for shrub and herb layers and floor litter was less than 5% for each forest type. When it comes to underground part, C stock of soil in the depth of 0-20 cm was 33.45, 54.07, 57.88 t·hm-2in PF, MF, and QF, reaching 23.58%, 36.43% and 33.04% of total C stock. Carbon stock for root was 2.04,1.92,1.49 t·hm-2for PF,QF and MF,accounting for 1.74%,1.26%, 1.19% of total C stock. Generally,C stock ratio among aboveground arborous layer,surface soil and root was 6 : 3 : 1 in temperate forest ecosystem in Taiyue Mountain.关键词
