| 摘 要： | Microbial crusts are attracting much interest in view of their possible uses in environmental conservation and ecological restoration of the arid and semiarid regions.Because algae play an irreplaceable important role in the early formation and the strengthening of microbial crusts,they are paid much more attention to than other cryptogams.In this paper,an overview of the current knowledge on the fine structure and development of microbial crust,focusing on the algal biomass,vertical distribution,succession,influential factors on algae,cohesion of soil stabilization,cementing mechanism for soil particles and the microalgal extracellular polymers is given,with particular emphasis on the authors' researches,and some prospects are put forward as well. |
