Abstract: Bryophyte is a kind of higher plants with small size and simple structure, being the transitional form from aquatic to terrestrial and the most original group of existing higher plants. With the development of scientific research, people realized more and more the important roles of bryophyte in the structure and function of ecosystem. Some researches were made on the roles of bryophyte in environmental bio-monitoring, water and soil conservation, and forest regeneration. Aiming at the hotspots in environmental sciences research, and from the viewpoints of global climate change and ecosystem carbon, nitrogen, and phosphorus cycles, this paper summarized the recent research progress in the ecological functions of bryophyte, which could be helpful to deepen our understanding on bryophyte and to promote the researches of its ecological functions.
