Abstract

Abstract:

The biological soil crust is important for maintaining stability in desert ecosystems. Therefore, the use of sand barriers as auxiliary measures to promote the formation and development of biological soil crust in arid areas is of great significance. In this paper, the effects of sand fixation by sand barriers (straw checkerboard, nylon grids, and covered nets) on the formation and development of biological soil crusts were studied using microbial high-throughput sequencing combined with soil physical and chemical properties determination. The results showed that the crust thickness under the covered nets was the thickest, although the colors of the crust in the straw checkerboard and nylon grids were similar to that of the algae crust. The proportions of clay and powder particles in the crust of the three types of sand barriers for sand fixation were significantly higher than that of the moving sand. The nutrition degree of the crust in the covered nets was the highest, indicating the highest degree of soil formation. From the composition analysis of fungi, bacteria, and blue-green algae in crusts from the three types of sand barrier, it was found that the proportions of Cyanobacteria and Leptolyngbya in the crust in the covered nets were higher than those in the crust in the straw checkerboard and nylon grids. In contrast, the proportions of Dothedeomycotes and Microcolleus were lower, and the number of unique microbial OUT was highest. Based on the previous process of soil crust formation and microbial succession in arid areas, it was inferred that the degree of crust development in the cover nets was likely higher than that in the straw checkerboard and nylon grids and that their formation and development trajectory differ. Therefore, among the three types of sand barriers, the covered nets for sand fixation were more suitable for biological soil crust formation and development.

Key words: biological soil crust, sand barrier, microbial succession, high-throughput sequencing
