摘　　要：通过对广西沿岸的南流江口和北仑河口的环境变化特征分析得出,江河径流、沿岸风浪流、周期性潮流是这2个河口地区环境变化的主要动力影响因素之一,三者的叠加不但使河口的大小、位置、形态等发生变化,而且还造成海(河)岸及河道的严重侵蚀。This paper presents a study on the characteristics of environmental change in the estuary districts of Lianzhou Bay and the Beilunhe river in Guangxi Province. The results show that the river runoff, coastwise storm currents and periodic tidal current are the major dynamic factors leading to the environmental change in the two estuary districts. The joint action of the threefactors not only changes the size, position and shape of the estuaries, but also causes serious erosion of the coasts, river bank and bed.
