摘要:

本文融合数据库技术、GIS 技术和软件工程方法,对中国科学院知识创新工程重要方向性项目“跨流域调水对陆地水循环影响与水安全研究”的核心软件平台“中国陆地水系统综合模拟与虚拟现实平台”的数据库功能进行了设计,并利用GIS 软件和商业数据库建立了“区域水系统多源信息数据库”。针对平台数据资料在空间分布、时间尺度和数据形式上的多样性分布格局,采用了时空同一化的集成策略和多数据库构建模式,有效消除了信息孤岛效应,实现了对跨流域水资源优化配置相关数据、信息和知识的综合利用,为平台提供一体化数据支撑服务。

Abstract:

Based on database technology, GIS technology and software engineering methods, this paper tries to design the database functionality of "China's land-based water system comprehensive simulation and virtual reality platform", which is the core software platform of the CAS Knowledge Innovation Program key project “Trans-basin water transfer and its impact on terrestrial water cycle and water safety". Using GIS software and commercial databases, a "multi-source database for regional water system" is established, with the diversity of spatial distribution, time scales, and data format, based on the integrated spatial-temporal strategy and the multi-database establishment frame, which effectively eliminate the effect of information silos, to achieve comprehensive utilization of data related to trans-basin water resources, and to provide integrated data support services for the platform.
