为研究非汛期江苏里下河沿海四港感潮河段的水动力和泥沙运动特性，对四港(射阳河、黄沙港、新洋港和斗龙港)闸门不同启闭运作方式下，大、中、小潮潮位、潮流量和输沙量进行了监测。结果表明，开闸时的潮位差明显低于关闸时的潮位差，大、中潮时夜潮潮差高于日潮潮差；射阳河的输沙率高于其余3港；落潮时含沙量小于涨潮含沙量；落潮历时大于涨潮历时。对于有效治理江苏沿海四港泥沙淤积，提供了理论参考。

In order to study the flow and sediment transport characteristic in tidal reaches of four coastal channels ( Sheyang River, Huangsha channel, Xinyang channel and Doulong channel) in Lixiahe area of Jiangsu Province in non-flood period, the tidal level, tidal current and tidal sediment discharge during spring, middle and small tide under different open-close operation modes were monitored. The results show that tidal level difference of open mode is lower than that of close mode;the tidal level difference of night tide is higher than that of solar tide in middle and spring tide;the sediment transport rate of Sheyang River is significantly higher than the other three; the suspended sediment concentration in ebb tide is significantly smaller than that in flood tide;the flood-tide duration is much longer than the ebb-tide duration.
