长江口水文监测站网选址合理性分析及优化

长江口河势演变复杂,涉水开发与保护项目众多,水文监测站点选址是一项技术难题。在分析确定水文站选址原则的基础上,结合近期河床演变过程以及涉水工程建设、生态环境保护的需求,研究提出了更为全面的站点选址原则。基于此,系统评价了长江口水文监测站网工程10个新建站点的选址合理性,并对5个不合理站址进行了优化,有力支撑了站网工程建设。长江口水文监测站网选址原则、合理性评价方法、站网优化思路可供长江口及其他河口类似工程的建设借鉴参考。

Study on site selection and optimization of hydrologic stations network in Yangtze River estuary

The riverbed evolution of Yangtze River estuary, where many water-related projects distribute, is complicated, so the site selection of hydrological stations in Yangtze estuary is a technically complex problem. Based on the analysis on site selection principles combined with recent development of the riverbed and the requirements of water-related projects construction and ecological environment protection, this paper puts forward more all-round site selection principles and systematically evaluates the rationality of 10 planned sites of hydrological stations in Yangtze River estuary. Five unreasonable sites are optimized. The suggested hydrological station selection principles, rationality evaluation method and network optimization approach can provide reference for the construction of hydrological station network in Yangtze River estuary and other estuaries.
