基于国产操作系统的海湾污染物扩散输运预报系统——以象山港为例

Pollutant diffusion and transport prediction system in a bay based on domestic operating system——a case study of Xiangshan Bay

在国产操作系统openEuler上构建了一个基于三维非结构网格水动力模型的污染物扩散输运预报系统。该系统采用操作系统、模型计算和数据可视化三层架构设计,提供了潮位和潮流模拟、选择站点释放污染物、污染物扩散输运预报、预报结果可视化等功能,并以象山港为例进行测试。结果表明:目前主流的非结构海洋模型可以成功移植到国产操作系统openEuler中,系统能正常运行且稳定可靠,可为海湾治理和污染预报提供参考,也可为后续数字地球提供海洋预报业务化平台。

A pollutant diffusion and transport prediction system based on three-dimensional unstructured grid hydrodynamic model is constructed on the domestic operating system openEuler. The system is designed a threelayer architecture of operating system, model calculation and data visualization, and provides functions such as tidal level and tidal current simulation, pollutant release at selected stations, pollutant diffusion and transport prediction, visualization of prediction results, which is tested with Xiangshan Bay as an example for testing,providing functions such as tide and tide simulation, pollutant release from selected stations, pollutant diffusion and transport forecast, and visualization of forecast results, and is tested with Xiangshan Port as an example. The results show that the current mainstream unstructured ocean model can be successfully transplanted into the domestic operating system openEuler, and the forecast system can run normally, stably and reliably, which could provide a reference for the governance and pollution forecast of bay and also provide an operational platform of marine forecasting for the Digital Earth in the future.
