广州海洋观测网规划建设及观测数据应用探讨

Discussion on Construction of Ocean Observing Network and Data Application in Guangzhou

阐述了广州海洋观测网建设的迫切性和必要性,对海洋观测网建设在海洋防灾减灾、海岸工程建设及海水养殖等方面的重要意义进行了分析说明。总结广州市海洋观测网建设现状和成果,并利用已有观测数据对2017年台风“天鸽”和“帕卡”期间广州海域水文气象特征、2015-2017年枯水期咸潮入侵特征进行了分析。研究表明,现有观测数据对台风和咸潮活动均具有较明显的反应,且对海洋防灾减灾工作具有重要的意义;为更有效地利用已有观测数据,将观测数据价值最大化,对观测网建设及运行过程中观测工作机制及业务化流程、数据质量控制、观测站布设合理性以及数据应用分析这几个方面存在的问题进行了探讨,提出了广州海洋观测网的优化、改进措施及未来发展方向。

The urgency and necessity of ocean observation network construction in Guangzhou are expounded and the significances of ocean observation network construction in marine disaster prevention and mitigation,coastal engineering construction and marine aquaculture are analyzed and illustrated.The status and results of the ocean observation network construction in Guangzhou are summarized and the existing observed data are used to analyze the hydrometeorological characteristics of the sea area of Guangzhou during the periods of typhoon“Hato”and“Pakhar”and the characteristics of tidal saltwater intrusion during the dry seasons from 2015 to 2017.The research results have revealed that the existing observed data can obviously reflect both typhoon and salty tide activities and have a great significance in marine disaster prevention and mitigation.For using the existing observed data more efficiently and maximizing the value of the observed data,problems in the aspects of observation mechanisms and business workflow,data quality control,rationality of the layout of observation stations and data application analysis are discussed and the measures of optimization and Improvement and the direction of future development of the ocean observation network construction in Guangzhou are put forward.
