چکیده

Tree species composition was important for carbon storage within the same climate range. To quantify the dynamics of ecosystem carbon allocation as affected by different tree species, we measured the above- and below-ground biomass accumulation in 22 years, as well as the tissue carbon concentrations of trees in Cunninghamia lanceolata plantation and Michelia macclurei plantation. Results indicated that M. macclurei plantation significantly stored more carbon (174.8 tons/hm2) than C. lanceolata plantation (154.3 tons/hm2). Most of the carbon was found in the soil pool (57.1% in M. macclurei plantation, 55.2% in C. lanceolata plantation). Tree and soil component of M. macclurei plantation possessed significantly higher carbon storage than that of C. lanceolata plantation (p <0.05). No significant difference was found in the carbon storage of understory and forest floor. These results suggest that the broadleaved species (M. macclurei) possesses greater carbon sequestration potential than the coniferous species (C. lanceolata) in southern China.

Biomass partition and carbon storage of Cunninghamia lanceolata chronosequence plantations in Dabie Mountains in East China

The quantification of biomass carbon pools is important for understanding carbon cycling in forest ecosystems. This study was designed to reveal the effects of stand age on biomass partitioning and carbon storage of Chinese fir plantation stands in Dabie Mountains of Anhui, East China. A total of six even-aged Chinese fir plantation stands along an age-sequence from 10 to 50 years were selected...

Effects of Increased Nitrogen Deposition and Rotation Length on Long-Term Productivity of Cunninghamia lanceolata Plantation in Southern China

Cunninghamia lanceolata (Lamb.) Hook. has been widely planted in subtropical China to meet increasing timber demands, leading to short-rotation practices that deplete soil nutrients. However, increased nitrogen (N) deposition offsets soil N depletion. While long-term experimental data investigating the coupled effects related to short rotation practices and increasing N deposition are scarce, a...

Effects of Thinning on Soil Organic Carbon Fractions and Soil Properties in Cunninghamia lanceolata Stands in Eastern China

Soil organic carbon (SOC) fractions, along with soil properties, are greatly affected by forest management. In this study, three thinning treatments: control (conventional management mode), moderate thinning intensity and heavy thinning intensity, were applied in Chinese fir (Cunninghamia lanceolata) plantations in eastern China. The dissolved organic carbon (DOC), soil light fraction organic c...

Comparative Analysis of the Chloroplast Genomic Information of Cunninghamia lanceolata (Lamb.) Hook with Sibling Species from the Genera Cryptomeria D. Don, Taiwania Hayata, and Calocedrus Kurz

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is an important coniferous tree species for timber production, which accounts for ~40% of log supply from plantations in southern China. Chloroplast genetic engineering is an exciting field to engineer several valuable tree traits. In this study, we revisited the published complete Chinese fir (NC_021437) and four other coniferous species chlor...

Development of a stem taper equation and modelling the effect of stand density on taper for Chinese fir plantations in Southern China.

Chinese fir (Cunninghamia lanceolata) is the most important commercial tree species in southern China. The objective of this study was to develop a variable taper equation for Chinese fir, and to quantify the effects of stand planting density on stem taper in Chinese fir. Five equations were fitted or evaluated using the diameter-height data from 293 Chinese fir trees sampled from stands with f...
