摘要
西南河流源区是我国水资源和水能资源的重要储备,国家自然科学基金委员会设立的"西南河流源区径流变化和适应性利用重大研究计划"改善该地区基础数据资料匮乏状况。为发挥该重大研究计划延续性作用,亟需研发西南河流源区数据管理与共享平台。从数据管理与共享角度出发,梳理出多源异构数据集成、数据质量保障、数据全流程管理、数据共享、专题数据展示等功能需求,提出"数据存储-应用支撑-业务逻辑-应用视图"平台框架,实现西南河流源区多源异构数据的一致性存储、"数据上传-评审-下载-评价"全流程管理及专题数据二三维一体化可视化展示。以数据质量为主线,提出"规范元数据体系+数据评审"双重质量控制流程。结合繁杂的数据类型和日益增加的数据量对数据管理提出更高要求,探究未来数据平台改进方向与思路。该研究将为研发适用于西南河流源区数据管理与共享的平台奠定坚实基础。
River source regions in southwest China are important reserve of water resources and water energy resources in China. The National Natural Science Foundation set up the "Major research plan on runoff change and adaptive utilization of river source regions in Southwest China" for improving the lack of basic data in this area. In order to play the continuation role of this major research program, it is urgent to develop a data management and sharing platform for the river source regions of the southwest China. From the perspective of data management and sharing, the functional needs including multi-source heterogeneous data integration, data quality assurance, data whole process management, data sharing, thematic data display are combed out. The platform framework of "data storage-application support-business logic-application view" is proposed to realize the consistent storage of multisource heterogeneous data, the whole process management of data upload, review-data evaluation, and the 2 D and 3 D integration visualization of thematic data of the river source regions of the southwest China. Taking data quality as the main line, the dual quality control process of "standard metadata system + data review" is put forward. Considering the complicated data types and increasing data volume, the future direction and thinking of data platform improvement are discussed. The above research will lay a solid foundation for the development of data management and sharing platform of the river source regions of the southwest China.
