英文摘要	In May to August of 2011, we assessed the effects of extreme rainfall (quantity and intensity) events on the carbon release from soils covered by different types of biological soil crusts (BSCs) in fixed sand dunes in the Tengger Desert, northern China. A Li-6400-09 Soil Chamber was used to measure the respiration rates of the BSCs immediately after the rainfall stopped, and continued until the respiration rates of the BSCs returned to the pre-rainfall basal rate. Our results showed that almost immediately after extreme rainfall events the respiration rates of algae crust and mixed crust were significantly inhibited, but moss crust was not significantly affected. The respiration rates of algae crust, mixed crust, and moss crust in extreme rainfall quantity and intensity events were, respectively, 0.12 and 0.41 mumolCO_ 2 /(m~ 2 ·s), 0.10 and 0.45 mumolCO_2 /(m~ 2 ·s), 0.83 and 1.69 mumol CO_ 2 /(m~ 2 ·s). Our study indicated that moss crust in the advanced succession stage can well adapt to extreme rainfall events in the short term.
