The Taklimakan desert is known as the largest dunefield in China and also as the world's second largest shifting sand desert. The Tarim Desert Highway, which is the first highway to cross the Taklimakan desert, was built for the purpose of oil and gas resources extraction in the Tarim area, as well as for the development of the southern area of the Xinjiang Uygur Autonomous Region. Shelterbelts have been planted along the highway to prevent shifting sand from burying the road. This paper analyzes the variations of moisture and salinity of the unirrigated desert soil under natural conditions in the center of Taklimakan Desert. A number of important findings indicating the moisture and salinity of the soil at capillary saturation zone were determined by the groundwater and related to the evaporation on the top. Salinity could be affected by vegetation, which was different from moisture in the soil. Meanwhile, clay layer played an important role in water preservation in the soil, which was also beneficial to the accumulation of salinity in soil. Compared with clay layer, vegetation was a decisive factor for the gathering of salinity. The findings were significant for reasonable adjustment of irrigation in the shelterbelts for the further development of the Tarim Desert Highway.

The Taklimakan Desert, located in the center of the Tarim Basin, northwest China, is the arid center of the Europe-Asia Continent. Due to the scarcity of surface water resources in the Taklimakan desert, the groundwater feeding water supply system was constructed by some ecological engineering and power engineering such as Tazhong Oilfield and the Shelter-forest Project of the Tarim Desert Highway in the hinterland of the desert. In this work, the chemistry data of shallow groundwater was obtained through positional observation section along Tarim Desert Highway in the Taklimakan desert and the main chemistry indicators of groundwater were carried out system analysis. The relationship between the major ions and TDS in the desert shallow groundwater was clarified by using descriptive statistical methods and correlation coefficient methods. The results were shown that the TDS in desert shallow groundwater was relatively high, its value ranged between 30.246 ~ 3.093 g/L. The spatial distribution characteristics were high in the north and lower in the south, and the south was slightly higher than central region.

The soils were collected from the Taklimakan Desert Highway shelter-belt with different planting years in Xinjiang, northwest of China. The soil organic carbon stork (SOCstork) in each layers. By chemical and physical pretreatment, we measured four carbon passive organic carbons, i.e., microaggregates organic carbon(OCMIA), humus organic carbon (OCHS), carbon resistance to oxidation (OCNaClO) and acid hydrolysis (OCHCl). The results showed that the OC and SOCstork was decreased with soil depth mainly in 0-50 cm. The artificial vegetation have more influence on TOC, OCMIA and OCHS than OCNaClO and OCHCl. The Tamarix chinensis shelter-belt is the most helpful for carbon sequestration in sandy soil and stabilization in surface layer than Calligonum mongolicunl and Haloxylon ammodendron.
