摘要 为了满足目前基于遥感技术的生态—水文过程研究需求,提出了一套基于水文过程变化下生态响应的监测技术体系;以及生态—水文遥感信息快速处理、生态—水文过程模拟和生态水文环境的三维虚拟表达于一体的框架结构。该框架体系利用大型遥感数据处理系统CASMImageInfo对遥感监测的生态水文过程要素进行快速处理;基干该系统插件式的开放体系结构,利用Visual Stadio,ArcGIS Engine以及SQL Server2000建立生态水文过程的空间分析、模拟模块以及生态水文数据数据库管理系统。此外,集成JX-4全数字摄影测量系统的技术优势,用于获取DEM等数据,并采用虚拟现实技术实现生态—水文环境的三维虚拟表达,为研究者基于遥感技术进行生态水文过程研究提供全数字化流水线式处理流程。
