| 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。

| Abstract: | 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. |
