摘　　要：从一维恒定对流扩散方程出发,通过简化变形推导出河口盐度和河口距离相关的指数型经验公式,以瓯江口为具体研究区域,运用实测资料进行验证,推求盐水入侵的最大距离,探讨河口盐水入侵与潮汐、径流等各种因素的影响关系,建立瓯江口最大咸潮入侵的快速预报模式。From the one-dimensional steady convection-diffusion equations, the experience exponential formula is derived that the estuary salinity is related to the distance from estuarine mouth by simplifying and deformation. The Oujiang River Estuary is chosen to be the study area, and the maximum distance of salt intrusion is acquired by verification of observation data, and explored the factors relationship between salt intrusion and tide, runoff and others. The fast prediction model of the maximum salt intrusion in the Ou jiang River Estuary is established.
