Abstract Experiment of artificially culturing moss crust has been carried out in Hobq Desert since 2006. The experiment results showed that the moss survival rate and coverage were closely related to soil matrix, precipitation, microhabitat and the development and reproduction identity of moss species. Bryum dichotomum Hedw. could form large area of moss crust owing to its highest survival rate and coverage, and its density was related to its coverage, while Didymodon vinealis(Brid.)Zand. played an important role in maintaining crust stability for its highest density in unit area. Moss species had a high speed of growth and reproduction in the prime of culture process as a result of consuming the nutrition of propagules, then it would stay at a level and the growth peak would not occur. The research provides experimental basis for artificially culturing moss crust and offers basic experiment data for in-depth exploration of the formation and maintainance mechanism of biological crust.
