Water affair disputes of interprovincial rivers in Yangtze River Valley are characterized by complex,sensitivity,multiformity and sudden occurrence.For designing a planning in advance and strengthening supervision to effectively avoid water-affair disputes,a Yangtze River Valley interprovincial rivers GIS has been established on the basis of both the 1∶250 000 and 1∶50 000 river vector database of Yangtze River Valley.This system adopts a three-layer distributed architecture,in which three kinds of technologies——GIS,WEB and database are fused.It possesses better foreseeable capacity and higher practicality,such as a long-distance visit of database.Through trial operations for a longer time,it is in good working order.
