火干扰强度对大兴安岭森林地上植被碳储量的影响
Effect of fire severity on carbon storage of aboveground vegetation in Great Xing'an Mountains, China
摘要
Abstract
Forest aboveground vegetation (trees,shrub,and grass) was sampled in the Huzhong forest region of the Great Xing'an Mountains under different fire severities.The allometric-equation and biomass-harvesting methods were employed to derive biomasses of tree,shrub,and grass layers,which were subsequently converted to carbon storage.The differences of carbon storage (tree,shrub,and grass layers) under different fire severities were analyzed.Results showed that fire severities significantly affected the aboveground carbon storage.The carbon storage was ranked in the order of unbumed>low-severity>moderate-severity>high-severity.At the same fire severity,the forest carbon storage was generally ranked in the order of tree>grass>shrub.At the different fire severities,the carbon storage was ranked in the order of unbumed>low-severity>moderate-severity>highseverity.The shrub layer carbon storage was ranked in the order of low-severity>unbumed>moderate-severity>high-severity.The grass layer carbon storage was ranked in the order of low-severity>unburned>high-severity>moderate-severity.The fire severities significantly affected carbon storage of tree and grass layers.The effect of fire severities on carbon storage in shrub layer was not significant.关键词
