水库运行后，由于其兴利调节作用，使下游河道的径流量发生改变，从而对感潮河段的盐度造成影响。因此，在结合相关地质及水文资料基础上，建立感潮河网一维水流—盐度耦合模型，对浙江某大型水库运行后，下游感潮河段的盐度变化进行研究。研究结果表明，水库运行后，盐水入侵的基本性质不会发生本质性的变化，水库的调节作用在一定时段和程度上对盐水入侵起到有利影响。

The operation of reservoir will change the downstream runoff and affect the salinity of tidal riv -er because of the effect of profiting regulation .Based on combining the geological with hydrological data , the paper established one-dimensional flow-salinity coupling model so as to study the salinity's variation in downstream section after the operation of a large reservoir in Zhejiang Province .The result showed that af-ter the operation of reservoir , the essence of saltwater intrusion will not change utterly .The reservoir regu-lation could have beneficial effect on the reduction of saltwater intrusion .
