Carbon conversion is one of the hot-point issues to address climate change, and an important component of global carbon budgets.【Objective】 Explore the significance of soil carbon processes and enhance development of strategies to establish and the calculate carbon storage.【Method】 The object of study was differed with soil textures, they were loam (A), clay loam (B), silty clay loam (C) and sand loam (D), respectively. A simulation experiment was conducted to study the effects of salt solution (NaCl, Na_2SO_4) with different mineralizations (0,2, 4, 6g/L) on soil organic carbon and inorganic carbon.【Result】 There were significant differences in soil salt, organic carbon and inorganic carbon for irrigating the different mineralization degree of NaCl and Na_2SO_4 solution in the four soil textures.【Conclusion】 There were extremely significant differences in soil organic carbon (p<0.01) between loam (A) and silty clay loam (C), and between clay loam (B) and sand loam (D),respectively. There were significant differences in soil organic carbon (p<0.05) between clay loam (B) and sand loam (D).Soil inorganic carbon had extremely significant differences(p<0.01 )between loam (A), clay loam (B), silty clay loam (C) and sand loam (D), respectively.
