摘要
为研究对虾养殖和水环境污染问题,通过调查,探讨了丁字湾的水交换特点和自净能力。丁字湾为典型半日潮海湾,进出海湾的潮流以往复流为主,平均每个潮周期湾内与湾外海水交换率大约为13.85%,湾内水交换50%大约需经过17个潮周期,即8.5d左右的时间。
Survey data was used in this study on the characteristics of water exchange andself purification in Dingzi Bay showing that: (1 ) The Dingzi my tides are regular semi-diurnal, the reciprocal current was the main component of tidal current. (2) On the average, the exchange rate of water inside and outside the bay over a tidal cycle was about 13. 85%, it tookaround 17 tidal cycles (roughly equal to 8. 5 days) for half of the original water inside the hey tobe exchanged with that outside the bay.
