Changes in carbon density for three old-growth forests on Changbai Mountain, Northeast China: 1981–2010

“…The estimates of carbon density for living trees and changes in this density over time are relatively reliable because: (1) the three permanent forest plots were selected because they were representative of typical forest types on Changbai Mountain (Dai et al 2011); (2) carbon contents in living trees were computed by using species-specific biomass equations developed from trees sampled in nearby forests; and (3) repeated measurements over time were used to quantify changes in forest biomass and carbon. Because a single 1-ha plot was used for each forest type, we were unable to compute the precision of carbon density estimates.…”

Atmospheric wet and litterfall mercury deposition at urban and rural sites in China

“…Changbai, northeastern China, which is one of the largest national forest reserves in China and covers an area of ∼ 1965 km 2 . The forest is dominated by tree species of Pinus koraiensis, Fraxinus mandshurica, Tilia amurensis, Acer mono and Quercus mongolica (Dai et al, 2011). There are no nearby sources at the MCB site and the predominant wind directions are from southwest to northwest, which could carry air pollutants from regional industrial and urbanized centers and northern China by long-range atmospheric transport (Fu et al, 2012b).…”

Long-term field studies of old-growth forests on Changbai Mountain in Northeast China

“…This special issue tends to cover broad disciplines/ approaches ranging from forest ecology to land use science, from ground observation to remote sensing/modeling, and from descriptive to analytical analysis. Dai et al (2011) investigated changes in forest structure and tree species composition, as well as population dynamics of the dominant tree species for two old-growth forests on Changbai Mountain from 1981 to 2010. They found that while stem density of the broad-leaved coniferous mixed forest at 740 m above sea level (asl) displayed almost no change, the total basal area increased from 36.2 to 46.5 m 2 ha −1 .…”
