AB  - Calligonum mongolicum is one of the dominant species in the Taklimakan Desert 
      highway shelterbelt, the litter of which plays an important role in carbon 
      cycling. After litter addition, we carried out a laboratory incubation experiment 
      to investigate the dynamics of soil CO(2) emission, soil organic carbon (SOC), 
      soluble organic carbon (DOC), pH, and electrical conductivity (EC) under the 
      condition of salt water (SW) and fresh water (FW) with field water holding 
      capacity of 25%, 50%, 75%, and 100%. The results showed that saline water 
      irrigation had an inhibitory effect on soil CO(2) emission. Under the four soil 
      water content treatments, the cumulative CO(2) emission of freshwater irrigation 
      increased by 1.9%-29.1% compared with that of saline irrigation. Cumulative soil 
      CO(2) emissions increased with increasing soil water content. With litter 
      addition, SOC decreased rapidly in the early stage, then gradually increased, and 
      finally tended to be stable. The DOC contents of each treatment following the 
      incubation increased by 41.3%-92.4% compared with that before the incubation. At 
      the end of incubation, soil pH of each treatment increased by 0.20-0.35. The EC 
      increased with the increases of soil water content. Under the four water content 
      conditions and compared with the situation before the incubation, the EC values 
      irrigated with SW increased by 0.11-0.79 mS.cm(-1), while those with FW increased 
      or decreased at the end of incubation. Cumulative soil CO(2) emission was 
      positively correlated with SOC, DOC, and pH, but not with soil water content. 
      Both saline irrigation and lower water content could inhibit CO(2) emission of 
      aeolian sandy soil under litter addition, while EC was significantly affected by 
      the quality of irrigation water and soil water content.
