Though interdisciplinary research has become a popular term in recent years ,the academic community holds various opinions on its meanings and is divided on many basic issues concerning the study . Therefore ,understanding its academic background and theoretical focus has become a fundamental premise for advancing interdisciplinary research both theoretically and practically .Due to the semantic diversity of the study and its diversity in research findings ,the selection of research methods and the completeness of literature data influence the overall understanding of the study and its developmental process . This article proposes to categorize interdisciplinary research publications by combining literature analysis and archival research methods while also considering research themes and the frequency of citations . Among the literatures of interdisciplinary research ,articles that haven't been referred directly in interdisciplinary research but are nevertheless frequently quoted by interdisciplinary researchers constitute the academic background of the study . These literatures fall into three main aspects : production mode ,research method of scientific knowledge and development of situated learning theory .Similarly ,frequently quoted literatures that contain the wording″interdisciplinary research″make up the theoretic framework ,while the less quoted compose the branches . Since the 1970s ,interdisciplinary research has advanced its discussion on various themes ,but has not yet reached a consensus on major issues such as its definition ,categorization and interdisciplinary integration .In recent years ,however ,the interdisciplinary research community has focused their attention on the integration between different fields of study . A new field of interdisciplinary studies is gradually taking form . Explorations into this new field lie in the measurement and evaluation of integration between various fields of study ,which has emerged as the primary difficulty in interdisciplinary research and will be the trend for future studies .
