摘　　要：利用2012—2015年瓯江河口水下地形资料,分析近期河口变化新特征。结果表明,瓯江河口河流段受河床采砂影响,河床高程降低剧烈,多年平均高水位下河床平均高程降低0.90 m,最大降幅可达5.00 m;梅岙以下江道受强烈的人工控制,整体格局稳定,2012—2015年降低约0.13 m。针对河口变化特征提出加强河口地形监测、加强采砂监管规划及其对涉水工程影响研究等方面的建议。Based on the underwater topographic data of the Oujiang River Estuary from 2012 to 2015,the new characteristics of the estuary changes in recent years were analyzed.The results showed that human sand excavation affects the section of the Oujiang River estuary,and the elevation of the river bed has fallen sharply.Under the average high water level for many years,the mean height of the riverbed was reduced by 0.90 m,and the maximum drop was up to 5.00 m.The river below Mei’ao were strongly controlled by humans,and the overall pattern was stable,with a decrease of about 0.13 m from 2012 to 2015.According to the characteristics of estuary changes,suggestions for strengthening estuarine terrain monitoring,improving sand mining supervision planning and its impact on wading projects are proposed.
