- Abstract:
- We chose Xinjiang Yanqi Basin as the research area and analyzed the different evolution stages of nitraria shrub dune and the physicochemical properties of between-dune lowland shrub dune soil. Results show that:(1) the silt, clay, organic matter and nutrient content of dune soil in different evolution stages were higher than the between-dune lowland, but the sand and pH values were lower; from development stage to the stable stage, the sand grains and pH values gradually reduced to the minimum, while the silt, clay, organic matter and nutrient content reached the highest values, from stable to the activation phase, sand grains and pH values increased sharply, and silt, clay, organic matter and nutrient content declined significantly; (2) from the entire profile view, due to the differences of erosion and accumulation of sand dune, with the increasing of depth, sand grains decreased first and then increased, while pH values, silt, clay, organic matter and nutrient contents were the opposite; the most sand grains were found in 0—15 cm soil layer, and the minimum was found in 15—45 cm soil layer; the lowest pH values, silt, clay, organic and nutrient content were detected in 0—15 cm soil layer, the highest values were found in 15—45 cm soil layer; (3) sand dune development and activation stage deflation are not conducive to the accumulation of organic matter, sand dune stabilizing will provide the strong protection for the dust sequestration, litter accumulation and microbial growth, it can improve clay surface sequestration, lichen like thin crust formation, and can increase soil organic matter.
