摘要

与次生林相比，原始天然林通常具有更高的生物多样性和生物量。本研究旨在分析南苏门答腊省木泗班原辛县泥炭地保护区老次生林(HST)、幼次生林(HSM)和老灌丛林(HBT)的物种组成、森林结构、生物量和碳储量。在HST、HSM和HBT的100 m × 100 m测量样地进行森林清查。结果表明:高寒林区直径≥10的树木有20科39种565棵，高寒林区有20科48种430棵，高寒林区有1科2种4棵。乔木级以上的高寒林带植被以金针花(Eugenia sp.)、Alseodaphne insignis和Adenanthera pavonina为主，高寒林带植被以Macaranga maingayi、Koompassia malaccensis和Alseodaphne insignis为主，高寒林带植被以相思(Acacia mangium)和刺槐(Acacia crassicarpa)为主。高通量林下立木生物量和碳储量分别为1 81、6 1 t/ha和90、79 t C/ha;HSM分别为117.04 t/ha和58.51 t/ha;而HBT分别为1.33 t/ha和0.66 t/ha。结果表明，高温合金的碳储量高于高温合金和高温合金。关键词:碳储量，碳吸收，木思板原，泥炭地，植被结构

Vegetation Structure and Carbon Stocks in Secondary Forests of Muara Merang Forest Complex, South Sumatera

Primary natural forests generally have higher biodiversity and biomass compared to secondary forests . Th is study aimed to analyze the species composition, forest structure, biomass and carbon stock in the Old Secondary Forest (HST), Young Secondary Forest (HSM), and Old Shrub Forest (HBT) in Peat land Protect ion Area, Musi Banyuasin Regency, South Sumatera Province. Forest inventory was conducted in measurement plots of 100 m x 100 m in the HST, HSM, and HBT . The results recorded 39 species of 20 famil ies and 565 standing trees with a diameter of ≥ 10 in the HST, 48 species of 20 famil ies and 430 standing trees in the HSM, and 2 species of 1 family and 4 standing trees in the HBT . Vegetation a t the tree level in the HST was dominated by Eugenia sp., Alseodaphne insignis, and Adenanthera pavonina , while t he HSM was dominated by Macaranga maingayi , Koompassia malaccensis , and Alseodaphne insignis , and the HBT was dominated by Acacia mangium and Acacia crassicarpa . The b iomass and carbon stock of standing tree s in the HST were 1 81 ,6 1 t/ha and 90 , 79 t C/ha , respectively; in the HSM were 117 , 04 t/ha and 58 , 51 t C/ha ; while in the HBT were 1 , 33 t/ha and 0 , 66 t C/ha. The results revealed that carbon stock in the HST was higher than that in the HSM and HST. Keywords: carbon stocks, carbon uptake, Musi Banyuasin , peat lands, vegetation structure

期刊介绍： The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
