摘　　要：水利数据共享方法缺少概念化表达和标准化支持,传统水利应用耦合数据和处理逻辑,无法自适应外部变化数据驱动的业务更新需求,也无法及时准确传递数据更新,为此,提出一种软件定义地图模式的数据共享方法。首先,用地图对异构多源数据对象集合进行抽象,约束地图作为水利应用交换和处理的基本单元,软件定义地图应用显式与控制器表达数据需求和预期数据状态;接着,通过向数据层设施传递应用需求,数据层设施是功能单一"匹配-行动"单元,通过匹配数据标识,进行简单处理之后,向其它数据层单元进行传递。经过黄河水利委员会综合管理信息资源共享整合项目应用验证,此模式可解决水利应用对一致性数据的共享需求。The lack of conceptual expression and standardization support for sharing data is common, which prevents the self-adaption of data-driven business update and data transmission of traditional hydrology applications. This paper thereafter proposes a novel data sharing method based on the software-defined mapping model （SDMM）.SDMM firstly restricts maps to being the basic processing and exchanging units of software-defined mapping applications （SDMAs）. And then, SDMAs explicitly express about the data requirement and status with software-defined mapping controller （SDMC）. By routing requirements of SDMAs, SDMC communicates with data panel elements which are simple“match-action”unit for executing the tasks from SDMC. After matching the identifiers of objects and executing tasks, the elements continue transferring data with other elements. Finally, a practical study on integrating and sharing hydrology data in Yellow River Conservancy is conducted. The validating project indicates that SDMM is suitable for sharing consistent data among the software-defined hydrology applications.
