摘要
针对目前生态环境监测中多源多尺度数据获取、定量遥感模型半自动化条件制约海量数据的快速处理与分析以及静态的时空快照服务难以表达动态变化过程等问题,该文从基于传感网的数据多元化实时感知获取、基于数据仓库的生态信息主题化动态汇聚、基于多尺度WFS的智能化服务、基于动态数据驱动的仿真动态模拟知识化应用方面考虑,设计湖泊流域生态环境动态监测服务系统。以鄱阳湖为例进行验证,为鄱阳湖流域的生态监测以及江西省生态文明试验区建设提供服务。
The following problems of ecological environment monitoring exist：multi-source and multiscale data acquisition and integration is pre-requisite;quick processing and analysis of huge amounts of satellite images subject to semi-automatic condition of quantitative remote sensing model,as well as a static snapshot service is difficult to express the spatio-temporal dynamic change process.Aimed at these present situation,the lake basin ecological environment dynamic monitoring service system was presented in the paper,considering the aspects of data real-time diversified acquisition based on the sensor network,ecological information themed dynamic gathering based on data warehouse,information sharing and intelligence services based on cloud computing,the dynamic simulation and knowledge-based applications based on dynamic data driven applications systems.Eventually validated in Poyang Lake area,it provided support services for ecological monitoring of Poyang Lake area.
