摘要

Leyte saba盆地泥炭地(LSBP)是菲律宾第二大泥炭地，面积为3088公顷(31平方公里)。利用异速生长方程对泥炭地沼泽林(SF)、湿地(ML)、农林业(AF)和农用地(AL) 4种生态类型的碳储量和固碳能力进行了估算。在凋落物C储量中，落叶C储量以落叶C储量最高，其次是顺丰、ML和AL。根系C储量和CO2封存量以顺丰最高，其次是AL和AF。在土壤泥炭深度上，土壤C含量在ML中最高，为32- 43%，顺丰为29- 34%，而AL和AF均为19- 37%。LSBP储存了36.6 Tg的C和134.5 Tg的CO2。这种碳储量可以代表热带泥炭碳的0.04%。

Carbon Storage of Leyte Sab-A Basin Peatland, Philippines

Leyte Sab-A Basin peatland (LSBP) is the second largest peatland in the Philippines and comprises 3,088 ha (31 km2). The study estimated the C storage and carbon sequestration capacity of the peatland’s four (4) ecotypes, namely, swamp forest (SF), marshland (ML), agroforestry (AF), and agricultural land (AL) using allometric equations. SF rendered the highest downed wood C-stocks followed by AL and AF. For the litter C-stocks, AF rendered the highest, followed by SF, ML, and AL. SF rendered the highest root C-stocks and CO2 sequestered, followed by AL and AF. C% is highest in ML with values ranging from 32-43 C% across the soil peat depth, while SF ranges from 29-34 C%, and AL and AF both with 19-37 C%. The LSBP stores 36.6 Tg of C and 134.5 Tg of CO2 sequestered. This C storage amount can represent 0.04% of tropical peat carbon.

期刊介绍： The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
