- Abstract
Microbiotic crusts widely distribute in arid and semi-arid desert areas, which are of great significance for maintaining the stability of desert ecosystem. Lichen crust, as important component and one of the main types of microbiotic crusts, has unique superiority in sand, carbon and nitrogen fixation. This paper summarizes the domestic and foreign research progress of desert lichen distribution, community composition and influence factors on regional and local scales, and discussed the function of possible biotic factors affecting desert lichen symbiosis on microscale. Although the existing studies have indicated that the climate type, precipitation, physical and chemical properties of soil, microtopography and temperature can impact lichen habit, species, abundance and coverage, and the biotic factors connected with lichen thallus, lichen crust and lichen crust soil are related to the function of maintaining life activities and distribution of lichens, the conclusions are still limited due to mainly lack of specialized researches on desert lichens on regional scale, and experimental exploration and validation on the lichen-associated biological functions. To a certain extent, all the mentioned limitations will restrict the study of large-scale application of artificial lichen crusts in deserts. The application of desert lichen crust is prospected in order to provide references for artificial construction of desert lichen crusts, arid and semi-arid desert control, and ecological restoration.
