For the difficulties that BIM technology could not manage ribbon projects and present surrounding spatial informations of projects，BIM and GIS data characteristics are analyzed and the method of BIM and GIS integration by format conversion，coordinate transformation，and data correlation is proposed in this paper. The method is applied in the Qichun waterway & channel regulation project. The results show that the BIM and GIS integration method is feasible and implements the functions including integrated view，display，management，and analysis of BIM and GIS data. The research results solve the difficulties that BIM could not manage the wide ranges of projects and reflect the surrounding environments，so they are important technical supports for the application of BIM and GIS technology in channel regulation project.
