“…A number of previous studies demonstrated that power function allometric equations based on DBH or squared DBH multiplied by H can be used to estimate tree biomass [29,35]. Allometric equations based on DBH are recommended because the measurement of H is time-consuming and less accurate than DBH [19,34,40,41].…”

“…The highest percentage was 73% for four Mediterranean oak forests in Spain [19]. The proportion of stem to total tree biomass has been used to infer the light conditions, soil nutrient and age stage at study sites [35,36]. For example, the ratios in Chinese pine were 46.9%, 72.2%, 70.6% and 70.7% for young, middle-aged, immature, and mature stands, respectively [34].…”

“…Moreover, soil organic matter is essential to ecosystem productivity and regeneration. Recently, many studies have focused on biomass, C, and nutrient storage during stand development [1,7,[34][35][36]48,55]. These studies provided a comprehensive understanding of the importance of considering the succession development of forest ecosystem C pools and the interaction with other nutrient elements, especially when estimating C sink potential over a life cycle.…”

“…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.…”

Chinese cork oak (Quercus variabilis) forests are protected on a large-scale under the Natural Forest Protection (NFP) program in China to improve the ecological environment. However, information about carbon (C) storage to increase C sequestration and sustainable management is lacking. Biomass, C, nitrogen (N) and phosphorus (P) storage of trees, shrubs, herb, litter and soil (0-100 cm) were determined from destructive tree sampling and plot level investigation in approximately 30-year old Chinese cork oak forests on the south slope of the Qinling Mountains. There was no significant difference in tree components' biomass estimation, with the exception of roots, among the available allometric equations developed from this study site and other previous study sites. Leaves had the highest C, N and P concentrations among tree components and stems were the major compartments for tree biomass, C, N and P storage. In contrast to finding no difference in N concentrations along the whole soil profile, higher C and P concentrations were observed in the upper 0-10 cm of soil than in the deeper soil layers. The ecosystem C, N, and P storage was 163.76, 18.54 and 2.50 t ha −1 , respectively. Soil (0-100 cm) contained the largest amount of C, N and P storage, accounting for 61.76%, 92.78% and 99.72% of the total ecosystem, followed by 36.14%, 6.03% and 0.23% for trees, and 2.10%, 1.19% and 0.03% for shrubs, herbs and litter, respectively. The equations accurately estimate ecosystem biomass, and the OPEN ACCESSForests 2015, 6 1240 knowledge of the distribution of C, N and P storage will contribute to increased C sequestration and sustainable management of Chinese cork oak forests under the NFP program.

“…4). According to the biomass equation Y = 0.232 × DBH 2.247 for lacebark pine (Li et al 2014) and carbon concentrations with a mean value of 0.5 (Li et al 2013), biomass and carbon storage at different DBHs (10.0 cm, 20.0 cm, 30.0 cm, 40.0 cm and 50.0 cm) may be predicted. As temperatures rise, biomass and carbon storage significantly increase (Table 3).…”

The correlation between tree-ring widths of lacebark pine and climate was investigated. Radial growth was positively correlated with monthly mean temperatures in the previous September and significantly negatively correlated with monthly mean and monthly maximum temperatures in March. There was no significant response to levels of precipitation. Treering variation was reconstructed by a transfer function using STD chronology and monthly mean temperatures. Assuming future temperature increases of 1.4 ЊC to 4.0 ЊC according to IPCC (2006), tree-ring widths would increase by 4.7% to 12.8%, and lacebark pine carbon pools would increase observably by 10.9% to 31.1%. Temperature has a positive impact on increasing biomass and hence carbon stored for lacebark pine. The results provide a theoretical reference for forest management and an evaluation of the capacity for forests to sequester carbon under climate change.Key words: lacebark pine, temperature changes, tree-ring growth, biomass, carbon stock RÉSUMÉCette étude porte sur la corrélation entre la largeur des anneaux de croissance du pin Napoléon et le climat. La croissance radiale a démontré une corrélation positive avec les températures moyennes du mois de septembre précédent et négative avec les températures moyennes et les températures maximales mensuelles du mois de mars. Le niveau de précipitation ne semblait pas avoir d' effet significatif. La variation dans la largeur des anneaux de croissance a été reproduite au moyen d'une fonction de transfert utilisant une chronologie STD et les températures mensuelles moyennes. Si la température devait augmenter de 1,4 °C à 4,0 °C dans le futur, tel que prévu par le GIEC (2006), la largeur des anneaux de croissance pourrait augmenter de 4,7 % à 12,8 % et la rétention de carbone chez le pin Napoléon afficherait une augmentation notable de 10,9 % à 31,1 %. La température a un effet positif sur l'accroissement de la biomasse et de ce fait sur le carbone séquestré par le pin Napoléon. Les résultats offrent une base théorique pour guider l'aménagement forestier et pour éva-luer la capacité des forêts à séquestrer le carbone en réponse aux changements climatiques.

Carbon partition among plant parts has a vital influence not only on the growth of individual plants but also on decomposition, carbon and nitrogen sequestration, and plant–atmosphere water exchange. Although many studies have tried to reveal plant growth mechanisms using observational living biomass or the biomass ratio among different organs, knowledge and understanding about carbon partition is still scarce and exists much uncertainty. In this work, a dataset about 1,089 sample plots of natural forests downloaded from the Chinese Ecosystem Research Network (CERN) was used to explore the dependences of net primary production (NPP) partition among foliage, stem and branch, and root on forest age, and mean annual temperature (MAT). The results found that (a) for all forest types, NPP partition had a significant relationship with forest age (p < 0.0001), that is, younger plants usually allocated a higher proportion of the NPP to stems, branches, and roots. As plants aged, an increasing proportion of the NPP was allocated to foliage; (b) MAT was negatively correlated with the proportions of the NPP allocated to foliage (F leaf; %) and roots (F root; %), while proportions of the NPP allocated to stems and branches (F stbr; %) were positively dependent on MAT; (c) independent effect analysis demonstrated that forest age had a larger direct influence on F leaf and F root, while MAT was relatively important for F stbr; and (d) forest age and MAT had a stronger combined effect on NPP allocation for broad‐leaved forests, while for needled‐leaved forests, the influences of forest age and MAT existed large differences among different forest types. This work not only is important for understanding the contribution of climatic factor and forest age on forest NPP partition, but also provides valuable ideas for developing ecological models.
