长江口水文监测站网布局研究

Study on layout of hydrologic network in the Changjiang estuary

本文在长江口区域潮位、流量、波浪、盐度、泥沙、水质和风速风向等水文要素逐项分析研究布设的基础上,按照"突出重点、一站多项、要素综合、精简节约"的基本思路,根据"保障重点、统筹兼顾,新老整合、充实完善,点面并举、驻巡结合"的基本原则,提出了以控制站和关键节点代表水文站为主体的长江口水文监测站网综合规划布局方案.

The layout of hydrologic network in the Changjiang estuary,based on analysis monitoring requirements of seven hydrological factors including tidal level,discharge,wave,salinity,sediment,water quality,wind speed and direction,was formulated with hydrological stations which controlled the critical regions or in the key nodes in this paper. The construction thought of hydrologic network is ＂highlight the main factor,multi-factor monitoring,integrated monitoring and retrench the network＂.The basic construction principles are ＂emphasizing focal point,holding overall consideration,integrating the old and the new stations,substantiating and improving the network,considering every station and the network simultaneously,combining flow measurement in fixed satation and the moving gauging. ＂
