To expand the coverage of spatial database data and improve data integrity, Taihu Basin Authority carries out database construction of 1：50 000 basic electronic map based on the 1：250 000 map. This article introduces the database construction background, material collection and database establishment process of the 1：50 000 basic electronic map of water resources for Taihu lake basin. The article provides graphic and attribute data review methods by taking river map layer for instance, and proposes some principles of river classification to meet the needs of results show. It is hoped that the article can provide primary data for further census for water, flood control, drought relief and water resources management.
