英文摘要	Biological soil crusts (BSCs), a layered structure formed by associations of soil organisms and topsoil, dominate arid and semiarid areas and serve important ecological functions in these areas (Eldridge and Greene, 1994). Nitrogen fixation by BSCs is the main source of N in arid and semi-arid ecosystems. Desiccation is the most notable factor that influences BSCs, which recover physiological activity only after moistening. By influencing the amount of carbohydrates, energy pools, nitrogen compounds, and nitrogenase enzyme, desiccation affects nitrogen fixation of BSCs (Belnap, 2003). Desiccation patterns are common and diverse due to the episodic and reduced precipitation leading to varied and complex effects of desiccation on nitrogen fixation, which require a deeper understanding. In addition, responses of nitrogen fixation to desiccation vary among different crust types and compositions (Jeffries et al.,1992). Therefore, it is essential to study the response of nitrogen fixation in BSCs with different successional stages to drought regimes.
