摘　　要：针对二维GIS技术的缺陷,将二维与三维GIS技术进行优势结合,可为水利信息化建设提供更好的服务与应用。阐述二维、三维集成技术在水利行业中的应用,从数据组织、功能集成设计、系统界面集成、系统特点4个方面对二维和三维技术的集成过程进行说明,结合集成技术在水利、河道洪水演进、三维空间分析及防洪抢险等方面给出相应的应用实例,如对抗洪地区进行可视化转换及对所获得的数据进行分析等。Aiming at defects of 2D GIS technology, it can provide better services for water conservancy informatization construction and application by combining the advantage of 2D and 3D GIS technology. The article expounds the application of 2D and 3D integrated technology in water conservancy industry. It introduces the integration process of 2D and 3D technology from four aspects of the data organization, function integration design, system integration and the characteristics of system. Combining with corresponding application examples of integration technology in water resources, river flood routing, 3D analysis and the application examples such as for disaster relief during flood control are given to convert the visualization and analyze data for the flood control areas.
