全国重点监测湖库可视化分析平台

Visualization analysis platform of national key monitoring lake and reservoir

为改善传统水资源监测范围小、对象单一、自动化与分析能力较差等不足,以水利部信息中心在全国范围内的重点监测湖库为研究对象,基于高分卫星影像,综合利用遥感和WebGIS技术设计并实现全国重点监测湖库可视化分析平台,实现湖库矢量和影像数据管理、多时相矢量查询与可视化、在线制作专题图等辅助监测分析功能。试验结果表明,系统能够实现从水体矢量到湖库动态监测产品的流程化管理,协助水利部门快速、直观地掌握我国重点湖库的基本情况和变化趋势,为全国湖库水情分析、水文水资源监测评价和生态环境保护提供科学依据。

In order to improve the defects such as small area,single object,lack of automation and poor interaction effect in the traditional water resources monitoring research area,this study is based on high-scoring satellite images based on the key monitoring lake reservoir of the information center of the Hydrological Bureau of the Ministry of Water Resources.Based on high-resolution satellite images,the comprehensive use of remote sensing technology and WebGIS technology design and realization of the national key monitoring lake library visualization analysis platform,the lake library vector and image data management,multi-tempon vector query and visualization,online production of thematic maps and other auxiliary monitoring and analysis functions.The experimental results show that the system can realize the process management of dynamic monitoring products from water vector to lake reservoir,help the water conservancy department to grasp the basic situation and changing trend of key lake reservoirin in China quickly and intuitively,and provide a scientific basis for water situation analysis,hydrology and water resources monitoring,ecological environment protection of national reservoirs and lakes.
