【摘要】 传统的基于GIS的溢油信息系统只能在单机或者局域网内使用,应用范围小且平台独立性不强。为了在溢油应急反应决策中提供更便捷、易于获取的GIS应用和应急信息,该文提出了构建基于网络地理信息系统(WebGIS)的海上溢油应急信息系统。在设计系统的体系结构和功能基础上,利用数值建模技术开发了溢油动态模拟模块,建立了应急信息数据库,运用GIS、动态Web及数据库技术开发了系统服务器端和客户端应用程序,并探讨了系统集成以及在WebGIS上实现数值模拟结果动态可视化表达的方法。初步研究结果表明,结合WebGIS、数据库、数值建模的综合方法提供了溢油事故应急所需的有效解决方案。更多还原

【Abstract】 Traditional GIS-based oil spill information system can be used only on networked PCs which are physically tied to locations with limited accesses and restricted to certain platforms of operating systems. In order to provide a more convenient, accessible GIS application and response information to support timely decision in oil spill emergency response, the paper proposed the construction of marine oil spill response information system based on WebGIS. Based on the system structure and functions, the authors developed the oil spill behavior simulation module using numerical modeling technique, established the response information databases, developed the system server and client application programs by using GIS, dynamic Web, database techniques, and also discussed the system integration and visual display of numerical simulation result on WebGIS. Preliminary results showed that such an integrated approach of combining WebGIS, database and numerical modeling provided effective solutions as needed in an oil spill contingency.更多还原
