Hydrogen is a kind of ideal clean energy sources．With low energy consumption，environmental protection and other advantages，biological hydrogen production technology become the hotspot of current study home and abroad．Considering from energy source point of view and environment point of view，it is very important to develo Ptechnology of hydrogen production from biomass．It attempts to analyzed the research of biohydrogen in foreign countries from 2000 to 2008 and drew its knowledge mapping. The knowledge mapping displays that there are two research groups on biohydrogen．The first research grou Pconcentrate on photoproduction of hydrogen from water,including algae and cyanobacteria；The second grou Pfocus on anaerobic fermentation of hydrogen, including photofermentation and dark fermentation．The ma Pshows the researchers of anaerobic fermentation of hdyrogen is the major category in biohydrogen.
