[Purpose/significance] This paper aims to research the integration of heterogeneous information in the process of data integration. Based on the accuracy requirements of literature information extraction in literature Meta-synthesis system, we proposed a heterogeneous information standardized approach by the case of resource and environment subject.[Method/process] Using the self-discipline ontology of resources and environment subject, we put forward the idea of heterogeneous information standardization process to guide to putting up literature comprehensive integration platform supporting comprehensive integration of human-computer interaction and information integration, through the analysis of standardizing of heterogeneous information in the geographic space, time and attribute extraction in resources and environment subject.[Result/conclusion] Finally, the paper realized the task of data preparation phase in literature Meta-synthesis, according to knowledge extraction and processing of documents from different sources in different data formats. The standardization of heterogeneous information is only the starting point of knowledge discovery process, and we will focus on the statistical analysis and visual display of standardized information to completely implement knowledge discovery process of literature meta-synthesis.
