Capacity of Forest Carbon Sequestration Driven by Npp Increasing in China
نویسندگان
چکیده
Forest ecosystem could significantly sequestrate some atmospheric CO2 and, therefore, partly mitigate current pressure on global warming. The carbon sequestration capacity of forest ecosystem is determined by both the NPP increase trend and turnover time. In order to estimate the capability of forest C sequestration in China, a carbon turnover model, which bases on NPP increase trend monitored by remote sensing and carbon turnover time derived from forest observed data, was designed. Modelled results illustrated that China forest is an apparent carbon sink with a magnitude of 0.052 PgC a-1, in which about 0.034 PgC a-1 in plant tissues and the other of 0.018 PgC a-1 in soil. The further analysis on carbon sequestration efficiency (CSE) indicated that the CSE value is controlled by carbon turnover time. *Corresponding author: [email protected]

Separating effects of changes in atmospheric composition, climate and land-use on carbon sequestration of U.S. Mid-Atlantic temperate forests
Terrestrial carbon dynamics have been vastly modified because of changes in atmospheric composition, climate, and land-use. However, few studies provide a complete analysis of the factors and interactions that affect carbon dynamics over a large landscape. This study examines how changes in atmospheric composition (CO2, O3 and N deposition), climate and land-use affected carbon dynamics and seq...
متن کاملEconomic Evaluation of Carbon Sequestration in Zagros Oak Forests (Case Study: The Pahnus Forest habitat, Chaharmahal and Bakhtiari Province)
Examining the economic value of carbon sequestration in forests is essential, given the risk of global climate change, which has posed a profound challenge to societies internationally. The present study investigates the amount of carbon sequestration and its economic value in the oak forests (Quercus brantii L.) of Pahnus forest habitat with an area of 990 ha, located in Chaharmahal va Bakhtia...
متن کاملImpacts of fine root turnover on forest NPP and soil C sequestration potential.
Estimates of forest net primary production (NPP) demand accurate estimates of root production and turnover. We assessed root turnover with the use of an isotope tracer in two forest free-air carbon dioxide enrichment experiments. Growth at elevated carbon dioxide did not accelerate root turnover in either the pine or the hardwood forest. Turnover of fine root carbon varied from 1.2 to 9 years, ...
متن کاملA Preliminary Study on the Carbon Dynamics of China’s Forest Ecosystems in the Past 20 Years
Carbon balance is characterized by the net ecosystem productivity (NEP), the difference between net primary productivity (NPP) and the heterotrophic respiration (Rh), namely the decomposition of dead organic matter by soil microbes. At the global scale, NEP is of great interest because it indicates the capacity of terrestrial ecosystems absorbing/releasing CO2 from/to the atmosphere. In this pa...

An improved individual-based forest ecosystem carbon budget model for China (FORCCHN) was applied to investigate the spatial-temporal dynamics of net primary productivity of different forest types in northeastern China. In this study, the forests of northeastern China were categorized into four ecological types according to their habitats and generic characteristics (evergreen broadleaf forest,...
