鄱阳湖水环境信息管理系统的设计

Design of Poyang Lake water environment information management system

针对鄱阳湖水环境信息化管理的迫切需求,设计并实现了鄱阳湖水环境信息管理系统,包括Web端子系统和移动端子系统。Web端主要采用Arc GIS API for Flex开发,基于Model Builder工具以及GP服务,采用反距离权重和克里金算法,实现了水质水位空间插值;利用线性权重法、简单平均法、指数平滑法建立了水质水位预测模型,通过调用Web Service实现了水质水位的预测;移动端主要采用Arc GIS API for Android开发,利用移动手机定位技术获取地理位置,并利用Web Service实现相关数据的上传。系统可以为鄱阳湖水环境信息的管理提供强有力的技术支撑,对相关系统的开发具有参考价值。

Responded to the urgent need of water environment information management of Poyang Lake, Poyang Lake water environment information management system was designed and developed. The system comprised two subsystems of Web-side and mobile-side. Web-side was mainly developed by AreGIS API for Flex. Based on Model Builder tools and GP services, and adopted models of inverse distance weighted and kriging to achieve the spatial in- terpolation of water quality and water level. Used the linear weighting methods, simple average methods and expo- nential smoothing methods to establish prediction models, and achieved the predictions of water quality and water level by calling WebService. Mobile-side was mainly developed by ArcGIS API for Android. Adopted mobile phone positioning technology to obtain geographical position data, and achieved the relevant data uploading by calling WebService. The system could provide strong technical support for water environment information management of Poyang Lake, and it has reference value for the development of related systems.
