国际生物制氢相关研究的知识图谱分析

氢气是一种理想的洁净能源。生物制氢技术具有能耗低、环保等优势，是目前国内外研究的热点。从能源和环境角度考虑，发展生物制氢技术都具有重要的意义。通过ISI Web of Knowledge网络数据库检索2000~2008年8月期间生物制氢的相关研究，利用作者共引分析方法，并绘制了知识图谱。该图谱显示出此研究领域存在两大主流学术群体：群体1，其研究焦点为光解水制氢两大类，包括藻类光合制氢和蓝细菌等光合细胞制氢；群体2，其研究聚集在厌氧发酵制氢研究方面，又分为暗发酵制氢和光发酵制氢。其中厌氧发酵制氢的研究人员比较密集，说明这方面的研究是目前该领域的重点。

The Knowledge Mapping Analysis on the Research of BioHydrogen

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.
