Abstract:: [Objective] To investigate the effects of soil texture on the development and structural stability of artificially cultivated moss crusts, thereby providing a scientific basis for ecological restoration and ecosystem management in arid and semi-arid regions. [Methods] Two soil types with distinct textures, namely loam soil (with 10.33% clay, 48.46% silt, and 41.21% sand ) and sandy soil(with 1.23% clay, 3.26% silt, and 95.51% sand), were selected for the artificial cultivation of moss crusts. The differences in developmental indicators such as crust coverage, biomass, and extracellular polysaccharide content of artificially cultivated moss crusts under the influence of soil texture and their effects on structural stability were explored. [Results] (1) Soil texture significantly affected the development of artificially cultivated moss crusts. Compared to sandy soil, the coverage, thickness, biomass, moss density, moss height, and extracellular polysaccharide content of artificially cultivated moss crusts cultivated on loam soil were significantly increased by 49.7%, 145.8%, 90.8%, 70.9%, 28.6%, and 78.4%, respectively. (2) The structural stability of artificially cultivated moss crusts cultivated on loam was significantly higher than that on sandy soil. At the end of the oscillation test, the cumulative mass loss rate of artificially cultivated moss crusts on loam soil was 69.3%, significantly lower than the 83.7% observed on sandy soil, representing a reduction of 28.8%.(3) The structural stability of artificially cultivated moss crusts under the influence of soil texture was significantly and positively correlated with moss crust thickness, biomass, moss height, and extracellular polysaccharide content, with biomass being the primary factor affecting structural stability. [Conclusion] Soil texture significantly affects the development of artificially cultivated moss crusts, thereby influencing their structural stability. Moss crusts cultivated on loam soil exhibit superior development and structural stability compared to those on sandy soil.
