“…Modeling methods were used to calculated soil carbon storage in China by Li et al [72] and Wu et al [73], and the results were 82.65 and 70.30 Pg, respectively. Based on data from the second national soil survey and 810 soil profiles from Northwest China especially from the Qinghai-Tibetan Plateau, Yang et al [74] used the relationships among organic carbon density, bulk density and depth change of soil profiles to estimate that the soil organic carbon pool in China was 69.10 Pg, while Li et al [75] found that the total soil organic carbon pool in China was 88.3 Pg by using 2456 soil profiles. China's soil information system database, which was developed with the change from the genetic soil classification of China to the USA soil classification system, has been used to connect the organic carbon data of soil types in total polygons to the "1 : 1000000 China soil map".…”

“…Yang et al (2010a) estimated the SIC stock of the Tibetan grasslands to 15.2 Pg. Temperature and precipitation both show significant relationships with SIC density (Li et al, 2007;Mi et al, 2008;Yang et al, 2010a).…”

“…On the scale of the whole of China, SOC densities are significantly influenced by temperature (Xie et al, 2007), while soil moisture and texture control SOC density in the Tibetan grasslands (Yang et al, 2008;Baumann et al, 2009). For SIC, total stocks of the top 1 m are estimated to vary from 53.3 Pg to 77.9 Pg Mi et al, 2008;Li et al, 2007) in China. Yang et al (2010a) estimated the SIC stock of the Tibetan grasslands to 15.2 Pg.…”

Abstract. Soil carbon (C) is the largest C pool in the terrestrial biosphere and includes both inorganic and organic components. Studying patterns and controls of soil C help us to understand and estimate potential responses of soil C to global change in the future. Here we analyzed topsoil data of 81 sites obtained from a regional survey across grasslands in the Inner Mongolia and on the Tibetan Plateau during 2006-2007, attempting to find the patterns and controls of soil inorganic carbon (SIC) and soil organic carbon (SOC). The averages of inorganic and organic carbon in the topsoil (0-20 cm) across the study region were 0.38 % and 3.63 %, ranging between 0.00-2.92 % and 0.32-26.17 % respectively. Both SIC and SOC in the Tibetan grasslands (0.51 % and 5.24 % respectively) were higher than those in the Inner Mongolian grasslands (0.21 % and 1.61 %). Regression tree analyses showed that the spatial pattern of SIC and SOC were controlled by different factors. Chemical and physical processes of soil formation drive the spatial pattern of SIC, while biotic processes drive the spatial pattern of SOC. SIC was controlled by soil acidification and other processes depending on soil pH. Vegetation type is the most important variable driving the spatial pattern of SOC. According to our models, given the acidification rate in Chinese grassland soils in the future is the same as that in Chinese cropland soils during the past two decades: 0.27 and 0.48 units per 20 yr in the Inner Mongolian grasslands and the Tibetan grasslands respectively, it will lead to a 30 % and 53 % decrease in SIC in the Inner Mongolian grasslands and the Tibetan grasslands respectively. However, negative relationship between soil pH and SOC suggests that acidification will inhibit decomposition of SOC, thus will not lead to a significant general loss of carbon from soils in these regions.

“…This result was also the reason for the decrease in the SIC to SOC ratio with plantation age. Although it is possible for the SOC to transform into SIC by the effect of temperature on the microcarbon cycle system "SOC-CO2-CaCO3" as Li et al 2007b), the opposite process dominated the soil of this arid region after the revegetation.…”

© iForest -Biogeosciences and Forestry IntroductionArid and semi-arid regions cover more than one-third of the surface of the Earth, making these systems the most common types of biomes in the world (Reynolds 2001, Gao et al. 2012. The vegetation and soils in these regions represent approximately 46% of the global terrestrial carbon (C) stock (Verhoef et al. 1996, Lal 2002. Thus, arid and semiarid ecosystems play an integral role in the response of the global C cycle to climate change (Melillo et al. 1993, Housman et al. 2006, Lufafa et al. 2008). However, ecosystems in these areas are particularly vulnerable to environmental constraints and human activities (Puigdefábregas & Mendizábal 1998, Gao et al. 2012. Previous studies showed that rising temperatures and shifting precipitation patterns associated with climate change will lead to the degeneration of community structures and functions in arid ecosystems (Ehleringer & Cooper 1988, Midgley et al. 2004. Elevated atmospheric CO2 concentrations may cause the temperature of arid regions to increase sharply (Schlesinger et al. 1990, Maestre & Cortina 2004. Areas affected by desertification have lost twothirds of their C, mainly through the loss of vegetation and soil organic matter (IPCC 1996).Revegetation is one of the most effective methods for combating desertification and preventing soil C loss in arid and semi-arid regions (Yang & Wu 2010, Amiraslani & Dragovich 2011, Corona et al. 2012, D'Odorico et al. 2013. Shrub species are usually selected for revegetation, and they are therefore the dominant vegetation in such regions (Lufafa et al. 2009, Zhang et al. 2009, Conti et al. 2013. Many studies on the C stock and allocation in shrub ecosystem of arid and semi-arid regions have been conducted on the Mediterranean coast, in Africa, and in Latin America (Farage et al. 2007, Trumper et al. 2008, Corona et al. 2012, RuizPeinado et al. 2013. Nevertheless, studies on this topic are scarce in China. China possesses 334 000 km 2 of desertified or desertification-prone lands, mainly in the north (Feng et al. 2000). Vegetation restoration, including revegetation using sand-binding species in desert regions to reduce the effects of desertification, has been applied to more than 2.4 million ha of degraded land in China (Li et al. 2004, 2007a, Zhang et al. 2009, Gao et al. 2012. Given the large distribution area, accurate and reliable estimates of C stock in the desertification regions are important in the development of effective policies and strategies to mitigate climate change. A number of studies have shown that stand age may have a significant effect on the changes in C stock and allocation among different ecosystem components, such as trees, understory vegetation, forest floor, and mineral soil (Turner et al. 1995, Peichl & Arain 2006, Peichl & Arain 2007, Noh et al. 2010. Tree biomass and C stock increase with stand age, and the allocation and growth rate of tree biomass and C pools vary across stands with different ages (Tobin & Nieuwenhuis 2007, Li et al. 2011, ...
