In this paper, the source data and computer standardization of environmental change database during historical times in China was expounded. Based on the technique of computer, database, the general design, main function and application prospect of the database was introduced. There are three kinds of source data including historical documents, instrumental data and natural evidence in the database, in which each kind of source data covers three main tables for keeping the original data (such as the document cards), raw data derived from the original data and the proxy data for environmental change which was reconstructed by the methodology for time series reconstruction during historical times respectively. The structure for the database includes two main parts,in which part one contains tables for saving the source data and part two serves as management ware for data table linkage and database running. There are four main functions for the database, including data browser and backup, data query and statistical analysis, data editing, appending, deletion and modification, and the user guide and help.
Keywords:historical times of source data  environmental change  database establishment
