Estimation of Carbon Stock and Carbon Sequestration Potential of Mid-subtropical Forest in Jinggang Mountain National Nature Reserve
摘要
Abstract
Forest plays the key role in the global terrestrial carbon cycling. Therefore, the estimation of carbon storage capacity of forest ecosystem and its influencing factors at different scales is of great importance for the researches of global carbon balance and carbon budget. So far, related studies have mainly focused on forest carbon sink function analysis of tropical and temperate forests, but less research for the carbon sink function of subtropical forest, especially the subtropical evergreen broad-leaved forest in the eastern part of China. Taken Jinggang Mountain National Nature Reserve as the typical representative of subtropical forest ecosystem, the sample plots were set according to different forest types, the carbon storage of forest vegetation in the study area was estimated using the classic method of volume-derived biomass based on field sampling and investigation data, and the carbon sequestration potential was calculated as the discrepancy between the carbon stock of referred ecosystem (carbon storage of old-growth forest) and the carbon stock (carbon storage of forest ecosystem in 2012). This research can help to define the contribution of subtropical forest ecosystems in the global carbon cycle. The results showed: (1) the vegetation carbon storage of forest ecosystem was 1589531 t with the carbon density of 7.29 kg·m-2 which was higher than the mean value in China and other countries located at similar latitudes. The evergreen broad-leaved forest vegetation had the maximum carbon density of 9.25 kg·m-2, followed by mixed coniferous broad leaved forest and mixed evergreen and deciduous broad leaved forest, with the carbon density of 8.12 and 7.83 kg·m-2, respectively; (2) the vegetation carbon density of old-growth forest was higher than the average vegetation carbon density for all forest types. The old-growth evergreen broad-leaved forest had the maximum vegetation carbon density of 10.53 kg·m-2; (3) the carbon sequestration potential of forest vegetation was 182868 t. The evergreen broad-leaved forest vegetation had the maximum carbon sequestration potential of 74086 t, followed by mixed evergreen and deciduous broad leaved forest, warm temperate coniferous forests and mixed coniferous broad leaved forest. The results suggest that the forest system in the study area has great carbon storage capacity.关键词
