【摘要】 根据１９９７年和１９９８年两次潍河河口水文调查资料分析了潍河河口的水文特征及建闸截流的影响．结果说明，潍河是一个Ｍ－２潮占主导地位的不规则半日潮弱潮河口．上游建闸截流使得河口５、６月份的水温降低而盐度增高，并减少了口门内重力环流的出现机率．更多还原

【Abstract】 The hydrodynamics in the Weihe River Estuary is analyzed by using a set data measured from May 1997 and June 1998 respectively. The results show that the estuary is micro-tidal, dominated by the M-2 component. The salinity is raised and the temperature is decreased, as well as the occasion of gravitational circulation is reduced, as the currents are cutted in the upstream of the estuary by a sluice gate.更多还原
