This paper uses geographic information system (GIS) as a tool to
study water resources management. Taking the irrigation area as an example,
according to the goal set by the system, the spatial data model and attribute
data model describing the state of water resources are established, the modular
construction method commonly used in software engineering is established,
and the design conception of geographic information system framework of
water resources management in the irrigation area is completed. The system has
been applied to water resources management in irrigated areas and achieved
good results.
