地球生物学是生命科学和地球科学两大基础学科交叉而成的学科。拟通过学科门类的知识流动和研究主题的演变了解地球生物学的形成、发展和演化趋势；通过科研团队的分析，提供全球科研团队的科研合作可能性；通过研究前沿和热点分析对科技创新提供参考。研究发现，地球生物学发展早期主要从地球科学学科汲取知识，而发展中后期被其他学科引用较多，存在明显的学术溢出情况，流入学科主要为环境/生态学、植物&动物科学、微生物学、生物&生物化学和分子生物学&遗传学。地球生物学的研究主题变化不明显，天体生物学可能成为未来重点发展方向之一。麻省理工学院和哈佛大学地球生物学组研究方向重合最多，合作也最紧密。

Geobiology， as an interdisciplinary subject， was formed by the intersection of life science and earth science. According to analyzing the knowledge flow of multiple disciplines and the evolution of research topics， we try to understand geobiology's formation， development， and evolution trend. Based on the analysis about relations among geobiological groups， the cooperation possibility of the global teams is provided. The analysis of research frontiers and hot spots also provides a reference for future scientific and technological innovations. In the early stage of geobiology， its knowledge was mainly derived from Geosciences. However， in the middle and late stages， it was widely cited by other disciplines， which resulted in apparent academic spillover. The primary inflow disciplines were Environment/Ecology， Plant & Animal Science， Microbiology， Biology & Biochemistry， and Molecular Biology & Genetics. In general， the research topics around geobiology do not have major changes， and astrobiology is projected to be one of the most important research areas in the future. The geobiology research groups from MIT and Harvard University have the most overlapping research directions and the closest cooperation.
