Mixed plantations of Chinese fir (Cunninghamia lanceolata, CL) and five broadleaf tree species (Ailanthus altissima (AA), Betula luminifera (BL), Sapindus mukurossi (SM), Tciliata varpubescens (TV) and Zelkova schnideriana (ZS)) were established. After 5 years, spatial distributions of carbon stocks were studied in Chinese fir monoculture and mixed plantations. Overstory tree carbon storages were significantly lower (P<0.05) in mixed plantations than that in Chinese fir monoculture plantations. Understory vegetation carbon storages were significantly lower (P<0.05) in CL+BL and CL+ZS plantations than in the monoculture plantations. No significant difference was observed between other mixed plantations and monoculture plantations. Litter carbon storage was significantly lower in CL+ZS plantations than in the monoculture plantations (P<0.05), there was no significant difference between other mixed plantations and monoculture plantations. Soil carbon storages (0-60 cm) in mixed plantations were higher than that in the monoculture plantations, except for CL+SM plantations. Total ecosystem carbon storage was no significant difference between monoculture and mixed plantations, except for CL+SM plantations. Nevertheless, spatial distribution of carbon storage was different among these mixed plantations.

Vegetation Carbon Storage

Forest structural change affects the forest’s growth and the carbon storage. Two treatments, thinning (30% thinning intensity) and underplanting plus thinning, are being implemented in a coastalMetasequoia glyptostroboidesforest shelterbelt in Eastern China. The vegetation carbon storage significantly increased in the underplanted and thinned treatments compared with that in the unthinned treatment (P<0.05). The soil and litterfall carbon storage in the underplanted treatment were significantly higher than those in the unthinned treatment (P<0.05). The total forest ecosystem carbon storage in the underplanted and thinned treatments increased by 35.3% and 26.3%, respectively, compared with that in the unthinned treatment, an increase that mainly came from the growth of vegetation aboveground. Total ecosystem carbon storage showed no significant difference between the underplanted and thinned treatments (P>0.05). The soil light fraction organic carbon (LFOC) was significantly higher at the 0–15 cm soil layer in the thinned and underplanted stands compared with that in the unthinned stand (P<0.05). The soil respiration of the underplanted treatment was significantly higher than that of the unthinned treatment only in July (P<0.05). This study concludes that 30% thinning and underplanting after thinning could be more favorable to carbon sequestration forM. glyptostroboidesplantations in the coastal areas of Eastern China.

Throughfall Exclusion

Soil water content is an important factor that influences plant growth of different forests, and then affecting the forest ecosystem carbon storage through the net primary productivity. In this study, a throughfall exclusion experiment was carried out to explore effects of drought on vegetation carbon storage in moso bamboo forest in North Zhejiang of China. The results were showed as follows. The vegetation carbon storage of moso bamboo forest under throughfall exclusion treatment was 14.35% lower than the control plots. And the net CO2 sequestration was 125.07% lower than the control plots. The litterfall in control plots has a tiny drop when compared with the throughfall exclusion plots. These results indicated that drought could reduce forest ecosystem carbon storage and carbon fixation capacity.

Mixed Plantation

Reforestation plays an important role in the carbon cycle and climate change. However, knowledge of ecosystem carbon sequestration through reforestation with mixed species is limited. Especially in dry hot valley of the Jinsha River, no studies cover total ecosystem carbon sequestration level in mature mixed plantations for a limited area of mixed plantations and difficulty in the sampling of plant roots and deep soil. In this study, carbon sequestration of seven mixed plantations of different ages in dry hot valley of the Jinsha River was investigated with analogous sites method. The results are as follows: 1) Deep soil organic carbon (SOC) storage significantly increased with stand age (p = 0.025), possibly due to fine root exudates and dissolved organic carbon transportation into deep soil and retention. 2) Total biomass carbon storage in the 30-year-old mixed plantation was 77.78 t C ha−1, 54 times reference wasteland and 9 times reference natural recovery shrub-grassland. However, total biomass carbon storage of 30-year-old mixed plantation was insignificantly lower than that of reference natural forest (p = 0.429). After 30 years of reforestation, plantation biomass carbon storage recovered to reference level, and its sequestration rate was 2.54 t C ha−1 yr−1. 3) The total ecosystem carbon storage of 30-year-old mixed plantation was 185.50 t C ha−1, 2.38 times reference wasteland, 2.29 times reference natural recovery shrub grassland, and 29% lower than reference natural forest. It indicated that niche complementary, good stand structure, and characteristics of dominant species Leucaena leucocephala in mixed plantations facilitate more rapid carbon sequestration, especially biomass carbon in the dry hot valley.

Solubilizing Activity

This paper considered whether it was possible to activate nonavailable phosphorus (P) with tree root organs in lateritic soils. We investigated the cell wall content and P-solubilizing activity of xylem and phloem from six different sizes of roots from 10, 22, and 34 year old plantations of the Chinese fir Cunninghamia lanceolata (Lamb.) Hook. We found that, on average, cell wall content accounted for 81.07% of the root biomass (dry mass), and the mean solubilization of aluminum-bound phosphate by cell wall preparations was 1.89 g·kg−1. Tissue type (i.e., phloem or xylem) had a significant effect on cell wall content, with more cell wall material in the xylem, whereas P-solubilizing activity was greater in the phloem. In addition, the cell wall content of xylem increased with increasing root diameter, but P-solubilizing activity did not. A significant difference was also observed among the P-solubilizing activity of the three age classes, with lower P-solubilizing activity in the roots of 10 year old trees than in those of 22 and 34 year old trees. Since the establishment of Chinese fir plantations is increasing in southern China, where lateritic soils are widely distributed, the findings of the present study undoubtedly provide pertinent information for improving the utilization of nonavailable P by the cell walls of tree roots.

The Impact

Land use/cover change (LUCC) has an important impact on the terrestrial carbon cycle. The spatial distribution of regional carbon reserves can provide the scientific basis for the management of ecosystem carbon storage and the formulation of ecological and environmental policies. This paper proposes a method combining the CA-based FLUS model and the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model to assess the temporal and spatial changes in ecosystem carbon storage due to land-use changes over 1990–2015 in the Qinghai Lake Basin (QLB). Furthermore, future ecosystem carbon storage is simulated and evaluated over 2020–2030 under three scenarios of natural growth (NG), cropland protection (CP), and ecological protection (EP). The long-term spatial variations in carbon storage in the QLB are discussed. The results show that: (1) Carbon storage in the QLB decreased at first (1990–2000) and increased later (2000–2010), with total carbon storage increasing by 1.60 Tg C (Teragram: a unit of mass equal to 1012 g). From 2010 to 2015, carbon storage displayed a downward trend, with a sharp decrease in wetlands and croplands as the main cause; (2) Under the NG scenario, carbon reserves decrease by 0.69 Tg C over 2020–2030. These reserves increase significantly by 6.77 Tg C and 7.54 Tg C under the CP and EP scenarios, respectively, thus promoting the benign development of the regional ecological environment. This study improves our understanding on the impact of land-use change on carbon storage for the QLB in the northeastern Qinghai–Tibetan Plateau (QTP).
