| Abstract: |
| This research take in wetland soil covered by two different plants in the Ebinur Lake as the research object. By the ways field sampling and laboratory analysis, we tested the soil covered by desert shrubs and microphanerophytes desert shrubs and calculated the carbon stock volume in 5 different soil layers. The results show that the soil carbon content in microphanerophytes desert is 19.44 g·kg-1 which is much higher than that in shrub desert, the maximum content of carbon in the shrub desert. The peak organic carbon content occurs in the soil's surface layer(0～20 cm), and the maximum organic carbon density also is presented in the soil's surface layer(0～20 cm). Soil in shrubs desert is 2.48 kg·m-2, soil in microphanerophytes desert is 6.37 kg·m-2. The calculation of soil accumulate stock volume of organic carbon show that the carbon accumulation, soil in desert shrubs is 344 856.23 kg, and which is 3 743 517.41 kg in microphanerophytes desert. Soil carbon acumulationed ability in the microphanerophytes desert is higher than the shrub desert. This research can provide scientific reference for soil carbon cycle in arid wetland region and ecological restoration of Ebinur lake. |
