感潮河流的潮差变化原因分析是当今研究的热点，为探究瓯江河口江心屿潮位站近10 a来潮差逐渐变大的原因，基于MIKE模型软件建立了瓯江河口一维水动力模型。通过模拟上游径流、江道地形等多种工况组合条件下的潮位过程，分析潮差的变化，得出江道地形的人为改变是导致潮差增大的主要原因。

Causes analysis on the tidal range changes of tidal river has became a hotspot in current research . In order to explore the reason why tidal range gradually increases in the Oujiang river in recent decades , a one-dimensional hydrodynamic model of Oujiang river was built based on the MIKE software module . By simulating the tidal process line of upstream runoff and river terrain under a variety of possible conditions ,authors made an analysis on the changes of tidal range ,and then got a conclusion that anthropogenic changes were the main reasons leading to increased tidal range . The research results provide a reference for estuary management .
