摘　　要：针对河流生态修复工程方案设计与实施过程中的复杂性,以及对多尺度、多来源、多类型等海量数据的需求,提出了采用空间数据引擎ArcSDE集成关系数据库Oracle的模式,应用地理信息系统GIS的线性参考系统与动态分段技术,以永定河为例,构建一个以河流生态修复相关数据信息为数据源的空间数据库。该方法不仅为永定河生态修复模拟评价与综合决策系统提供了有效的数据支撑,同时也为确定河流生态修复工程方案提供了一个有效的辅助工具。In order to provide optimal schemes in design and assessment of the river ecosystem restoration, an effective approach for processing mass data is presented with multi-scales, multi-sources, and multi-types. Particularly, the pattern of spatial data engine ArcSDE is integrated with the relational database Oracle and GIS linear reference system as well as the dynamic segmentation. An ecological restoration spatial database is established, as a case study, for Yongding River, to provide an effective data support for assessment and decision-making for the Yongding River ecological restoration. It is demonstrated that the proposed approach is effective and practical for data supporting in assessment and decision-making for the ecosystem restoration of artificially recharged rivers.
