摘要

地理信息系统（GIS）中的水文数据模型是GIS在水文水资源应用中的核心和基础。结合GIS在水文水资源中应用的现状与需求，分析和总结了2种GIS水文数据模型；从构造GIS水文地理空间数据库的角度出发，对与水文现象相关的各种地理特征进行深刻认识和理解，在此基础上提出了面向对象的GIS水文数据模型设计的结构和要点。

Abstract

The spatial data model of GIS is the core and basis for its application in hydrology and water resources management. In combination with the current practice and requirements, two kinds of hydrological data models of GIS were analyzed and summarized. The spatial and temporal distribution features of the hydrological variations were deeply discussed and explored during the process of constructing hydro - spatial database of GIS. Finally an object - oriented hydrologic data model of GIS was presented.
