Résumé partiel
As one of the main dominant species in the Taklimakan Desert Highway Shelterbelt,S.sibiricum has the highest litter reserve among all vegetation types for sand fixation.Calligonum Mongolicum as one of the main trees in the Taklimakan Desert Highway Shelterbelt,Calligonum Mongolicum has the highest litter reserve among all vegetation types for sand fixation.By exploring the changing law of litter decomposition under different environmental factors,it provides theoretical support for the nutrient material cycle of the Tarim Desert Highway Shelter Forest,which is of great significance for accurately estimating the material cycle and energy conversion in the area.In this paper,through indoor cultivation,the CO2 and N2O emissions process of sandy sandy soil under the conditions of fresh water(S0:0 g·L-1)and salt water(S1:4 g·L-1,S2:8 g·L-1,S3:16g·L-1)irrigation with different water content（W1:25%field water holding capacity,W2:50%field water holding capacity）,soil organic carbon（SOC）and inorganic carbon.（SIC）,soluble organic carbon（DOC）,nitrate nitrogen（NO3—N）,ammonium nitrogen（NH4+-N）,dynamic changes of p H and EC were explored.The
