Patterns of Biomass and Carbon Distribution across a Chronosequence of Chinese Pine (Pinus tabulaeformis) Forests

Abstract: Patterns of biomass and carbon (C) storage distribution across Chinese pine (Pinus tabulaeformis) natural secondary forests are poorly documented. The objectives of this study were to examine the biomass and C pools of the major ecosystem components in a replicated age sequence of P. tabulaeformis secondary forest stands in Northern China. Within each stand, biomass of above- and belowground tree, understory (shrub and herb), and forest floor were determined from plot-level investigation and destructive sampli… Show more

“…Diameter at breast height (DBH) and height (H) were measured for all trees (DBH ≥ 5.0 cm) in each plot. In early August 2013, five Chinese cork oak trees within representative stand-specific DBH range were selected and harvested destructively in each stand following a previously published harvest method [19,[27][28][29][34][35][36]. Trees were cut near the ground surface, after measurement of the total H of each tree, the tree stem was first cut open at 1.3 m, and then the top part of stem (from 1.3 m to the tips) was divided into 1-m-long sections.…”

“…Shrub and herb biomass was determined using total harvesting destructive sampling techniques [34]. Sampling of the shrub layer and herb layer was conducted in five 2 m × 2 m subplots and 1 m × 1 m subplots, respectively.…”

“…For instance, the mean soil organic carbon was 22.7 g¨kg´1 in the plantation, which was significantly lower than the corresponding 44.9 g¨kg´1 in the natural forest. As a result, the site productivity and N availability is low as had been reported previously for the temperate forest [13,30,37]. It has also been suggested that N addition to N-limited forests will initially stimulate microbial activity, but eventually results in a carbon-limited state when microbial demand for N has been satisfied [6].…”

“…This nature reserve consists of an area of 3.355×10 4 ha with elevations ranging from 625 to 1,738 m. The region is in China's temperate zone -part of a semi-humid and semi-arid continental monsoon mountain climate. The long-term mean annual precipitation is 550 mm and the mean annual temperature is 7.3ºC, with monthly average temperatures ranging from -10.8ºC (January) to 22.9ºC (July) [29]. By and large, the reserve has a brown and cinnamon type of soil, classified as Eutriccambisol [30].…”
