摘要
随着水文信息管理现代化水平的不断提高、水文信息的爆炸增长,传统的水情信息数据管理方式存在可视化效果差、信息单一、缺乏空间管理和管理低效等问题。针对当前地理信息相关的水文信息占到总信息量的85%以上的实际需求,设计和实现了基于GIS(geographic information system,地理信息系统)的水文信息管理系统。将GIS空间信息技术、空间数据技术和空间分析技术相结合,有效整合了空间数据、属性数据和关系数据,实现数据资源的集中管理和分布应用。将城市河流水文信息数据资源融入系统中,实现监测数据管理,污染源信息数据管理,监测数据分析、污染源排放量的趋势分析和对比统计分析等功能,提高水文信息在现代城市中运作的高效性。通过实际的数据进行验证,较好地实现了系统设计的多项功能等。满足了城市水文信息管理系统需求,为水文信息管理系统的研究与应用提供了实际的技术参考。
With the continuous improvement of the modernization level of hydrological information management and the explosive growth of hydrological information,the traditional methods of hydrological information data management has some problems,such as poor visualization effect,single information,lack of spatial management and inefficient management.In view of the actual demand that the hydrological information related to the current geographic information accounts for more than 85%of the total information,we design and realize the hydrological information management system based on GIS,which integrates the spatial data,attribute data and relation data effectively and realizes the centralized management and distribution application of data resources by using the combination of GIS spatial information technology,spatial data technology and spatial analysis technology.The hydrological information data resources of urban rivers are integrated into the system to realize the functions of monitoring data management,pollution source information data management,monitoring data analysis,trend analysis and comparative statistical analysis of pollution source emissions,so as to improve the efficiency of hydrological information operation in modern cities.Through the verification of the actual data,the system design functions are well realized,which meets the needs of urban hydrological information management system and provides practical technical reference for the research and application of hydrological information management system.
