GIS技术在水文水资源领域的应用现状与展望

水文水资源领域引入GIS地理信息系统,为水文水资源管理、查询、分析和模拟提供了一条加快捷有效的途径。GIS地理信息系统在水文水资源领域的应用主要有五个方面:地表水资源及地下水资源的空间分布和调配;流域面雨量计算;地下水资源勘查;水文模拟及水情预报。GIS地理信息系统在水文水资源领域应用的主要发展趋势包括四个方面:加强应用标准和规范的研究和制定;建立具有水文水资源特色的地理空间数据库;GIS融合水文水资源专业模型;GIS软件向多维发展。

Current situation and Prospect of application of GIS technology in the field of hydrology and water resources

GIS geographic information system into the field of hydrology and water resources ,provides a fast and effective way for hydrology and water resources management,query,analysis and simulation.Application of GIS geographic information system in the field of hydrology and water resources mainly have five aspects：spa-tial distribution and allocation of surface water resources and groundwater resources;areal rainfall calculation;groundwater resources exploration;hydrological modelling and forecasting.The main development trend of GIS geographic information system application in the field of hydrology and water resources include four aspects：strengthening the research and formulation of the application standards and specifications;build up character-istic of hydrology and Water Resources Geographic Spatial Database;GIS fusion of hydrology and water re-sources professional model;GIS software development to multi dimension.
