长江口数字化信息建设初步构想

随着长江口12.5 m深水航道的建成通航，维护及管理的重要性凸显。信息化建设可进一步提高工作效能，为航 道水深保障提供坚实的信息基础。分析长江口数字信息化建设的背景和必要性，根据建设需求，对长江口数字化信息建设 的功能需求、总体目标及总体框架结构建设提出一些初步构想。结果表明：长江口数字化信息建设功能模块应包含航道维 护管理、航道行政管理、航道资产管理、航道智能监控、水下地形动态监测、对外信息服务等。长江口数字信息化建设预 期总体目标是建成“三大平台，两大系统”。

Preliminary idea on digital information construction in the Yangtze estuary

Following completion of the Yangtze estuary deep-water channel, the importance of maintenance and management becomes highlights. Informatization construction can further improve the working efficiency, providing a solid information base for the channel depth. This paper introduces the characteristics and necessity of digital information construction in the Yangtze estuary. According to the demand of the construction, this paper puts forward some preliminary idea of the target and framework of digital information construction of the Yangtze estuary. The results show that the Yangtze estuary digital information construction should contain the maintenance and management of waterway, waterway administrative management, asset management, channel intelligent monitoring, underwater terrain, dynamic monitoring of foreign information service. The general goal of Yangtze estuary digital information construction is building three big platform frameworks and two systems.
