Abstract: Bryophytes are effective accumulators for chemical elements,which can indicate the quality and change of environment.This paper illustrated the composition,concentration,origin,and characteristics of chemical elements in bryophytes,described the influence factors,and provided theoretical foundation for taking bryophytes as indicators.There were abundant elements in bryophytes coming from atmospheric depositions,such as precipitation,dust,eluviations etc,and substrate,such as soil and rock.The element concentrations in bryophytes showed great differences among different areas,ecosystems,and seasons.Environmental conditions,such as area,ecosystems,and seasons,could be indicated by the different concentrations of elements in bryophytes.
