中文摘要：

水利信息化系统通常是数据密集型系统,对防汛预警等业务的数据实时查询要求高。当前,应用于水利系统的图形可视化技术还需要克服操作复杂,实现过程繁琐、效率低、缺乏通用性和可操作性等问题。利用可视化评估准则,对比当前流行的几种可视化技术,着重分析其渲染功能和使用性能,实验验证ECharts不仅能满足水利系统对业务数据进行快速、高效的展示的需求,而且简单适用,方便操作。结合水利系统智慧滁河管理项目,提出一种基于ECharts可视化工具的水利系统开发模型,为水利系统可视化提供技术支持和科学依据。

英文摘要：

Water resources information system is a data intensive system. In flood warning and other services, the real-time query of data requires high efficiency. At present, the graphics visualization technology of water conservancy system needs to over- come the problems such as complex operation, low complexity, low efficiency, lack of generality and operability. In this paper, we use the visual evaluation criteria to compare the current popular visualization technology and analyze its rendering function and performance. The experimental results show that ECharts not only meets the demand of water resources system to display the business data quickly and efficiently, but also is simple and convenient to operate. Finally, based on the Chuhe project, the paper proposes a water conservancy system development model based on the visual tool ECharts, to provide technical support and scientific basis for the visualization of water conservancy system.
