Figure 1.
Average monthly climatic data of the study region during experimental periods from July 2012 to June 2013.
Table 1.
Summary of characteristics of the different sites.
Figure 2.
Daily and seasonal variations in soil respiration (SR) in the grassland (A), shrubland (B) and plantation (C) sites, respectively.
Note: Time of x-axis is Chinese Standard Time (UTC+8). Error bars are standard error of means (n = 9).
Figure 3.
Temporal variations in SR (A), ST at 10 cm depth (B) and SM at 10 cm depth (C) for the three different sites.
SR, ST and SM represents soil respiration, soil temperature and soil moisture, respectively. Error bars are standard error of means (n = 9).

Effects of soil temperature and soil moisture on the variation in soil respiration rate of different sites during the experimental period.
Figure 4.
Comparison of “measured” and “modeled” annul soil C flux from the different sites.
*denotes statistical significance using a pairwise t test comparing “measured” with “modeled” annual values at each site.
Figure 5.
Cumulative soil C flux (g C m−2) for Winter (December-February), Spring and Fall (March-April and October-November), and Growing season (May-September) in the three different sites.
Error bars are standard error of means (n = 3). Different letters denote significant differences as determined by Tukey’s HSD test.
