Abstract:

In recent years,alona with the develop ment of computer science,Geograp hic information systems(GIS) and Remote sensing ( RS) technology,the study of Dist ributed Hydrological Model (DHM) has also made quick progress. First the applications of GIS in DHM were introduced, and four different approaches widely used to integrate GIS with DHM were addressed.Based on the analysis of the advantages and disadantages of these approaches,the author developed the GIS-based Distributed Time Variant Gain Model(DTVGM) system by coupling mechanism of water cycle wit h system theory,which integrate GIS and DHM by means of loosing coupling. The system was proved valid and efficient by the case study in Gansu province Banqiao basin.

Key words: geograp hicinformation systems, distributed hydrological model, coupling, Banqiao basin
