Abstract: GIS coupling technology is an effective approach to obtain accurate results about the comprehensive assessment of ecological riparian zone. The coupling techniques, including database design, accessing way of assessment model, visualization of assessed result, etc., were introduced. The logical structure and physical structure for different assessment databases were designed by use of the map-layer structure and relation table; the relation table and model dictionary were adopted as the way of data storage in the descriptive assessment model and the computational assessment model, respectively; the results of assessment were reflected with the thematic map. As a result, the GIS coupling technology can give a direct and reasonable assessed result of ecological riparian zone.
