【摘要】：目前,各种信息数据库的建设已成为国家科技发展和不断进步的标志。开发和利用海洋资源的技术也日趋成熟,对近海环境动力信息进行即时的更新、合理的加工、科学的管理显得越来越重要。青岛地处山东半岛南端，海岸线长730.64Km，海域面积1.22万Km2，海洋是青岛最大的地缘优势，也是青岛发展的最大潜力，因此青岛拥有打造我国蓝色硅谷的天然优势，开发海洋资源是传承海洋文化、创新发展海洋经济的客观需要，而构建一个稳定的，共享的，交流方便的青岛近海环境要素数据库对于青岛开发蓝色经济区，综合利用海洋资源十分必要。港口、海岸工程及近海工程涉及风、海浪、潮汐、海流等多种动力要素，数据的获取途径众多、量大，不便于对其进行管理以及分析处理。将青岛近海环境动力信息整理加工，整合成为准确、便于获取的数据库资料，将对该地区的风、浪、潮、流四种要素的应用提供便利条件。本文首先收集并整理了近年来青岛近海风场以及水深数据，利用该资料建立了青岛近海水动力数学模型，对该区域波浪、海流、潮汐数据进行数值模拟，并以鳌山卫实测波高资料进行验证。通过验证，模拟结果与实测数据吻合良好，说明此模型可以准确对青岛近海环境动力进行模拟。基于水动力环境模拟数据基础之上，将获得的模拟结果按照空间、时间进行分类整理，并进行数值分析，获得风、浪、潮、流四种要素的时空变化特点。最后，本文利用MySQL软件构建了完整的青岛近海环境动力要素数据库。
[Abstract]:At present, the construction of various information databases has become a symbol of the development and continuous progress of national science and technology. The technology of developing and utilizing marine resources is becoming more and more mature. It is more and more important to update the dynamic information of offshore environment immediately, process it reasonably and manage scientifically. Qingdao is located at the southern tip of Shandong Peninsula with a coastline of 730.64km. The sea area of 12200 Km2, is Qingdao's greatest geographical advantage and the greatest potential for Qingdao's development. Therefore, Qingdao has the natural advantage of building blue Silicon Valley in China. The development of marine resources is the objective need of inheriting marine culture, innovating and developing marine economy, and building a stable and shared ocean. The database of Qingdao offshore environmental elements is very necessary for Qingdao to develop blue economic zone and make comprehensive utilization of marine resources. Port, coastal engineering and offshore engineering involve many dynamic factors, such as wind, wave, tide, current and so on. There are many ways to obtain data, so it is not convenient to manage and analyze and process it. The collation and processing of Qingdao offshore environmental dynamic information into accurate and easy to obtain database data will provide convenient conditions for the application of wind, wave, tide and current in this area. In this paper, the data of Qingdao offshore wind field and water depth in recent years are collected and sorted out, and the hydrodynamic mathematical model of Qingdao offshore is established by using this data. The wave, current and tide data in this area are simulated and verified by the wave height data of Aoshan Wei. The results show that the simulation results are in good agreement with the measured data, which shows that the model can accurately simulate the coastal environmental dynamics of Qingdao. Based on the hydrodynamic environment simulation data, the simulation results are classified according to space and time, and numerical analysis is carried out to obtain the temporal and spatial variation characteristics of wind, wave, tide and current. Finally, a complete database of dynamic elements of Qingdao offshore environment is constructed by using MySQL software.
