摘要： 研究对翔实的实测数据进行深入分析,总结出2009/2010年枯水期珠江口磨刀门水道咸潮具有出现早、来势猛、影响大的显著特征。通过对此次强咸潮上溯的影响因素进行分析,研究认为:2009年8月以后,气候变化导致的珠江流域降水异常偏少,径流锐减是2009/2010年枯水期珠江口磨刀门水道强咸潮出现的主要原因;潮汐是驱动磨刀门水道咸潮上溯的主要动力因素,潮汐愈强咸潮愈强;海平面上升是磨刀门水道强咸潮出现的重要影响因素。在全球气候变暖和海平面上升的背景下,研究对深入了解河口区淡水资源的合理开发利用,尤其是对保障河口区城乡供水安全具有重要的参考意义。

Abstract: In this study, measured data was analyzed deeply and three significant characteristics which were "appeared early", "fierce" and "affected heavily" were summed up for saltwater intrusion in Modaomen channel of the Pearl River Estuary in the dry season during 2009-2010. The factors of the saltwater intrusion were analyzed, and the results showed that: the main factor for the severe saltwater intrusion of Modaomen channel in the dry season during 2009-2010 was that the precipitation was extremely scarce due to climate change and the runoff dropped sharply in the Pearl River Basin after August 2009; tide was an important driven factor of saltwater intrusion in Modaomen channel, stronger tide led to severe saltwater intrusion; sea-level rise was another important factor to the severe saltwater intrusion in Modaomen channel. In the context of global warming and sea level rising, this study is of great significance for understanding rational development and utilization of fresh water resources in the estuary deeply, especially for the security of water supplies in rural and urban areas of estuary.

Key words: fresh water resources, saltwater intrusion, channel, runoff, tide, sea-level rise
