| 摘 要： | 为研究广西典型海湾物质输运的时间尺度,建立了钦州湾和铁山港湾水动力与物质输运数学模型,计算了钦州湾和铁山港湾物质输运的滞留时间和半交换周期,探讨了滞留时间随入海径流量的变化以及与半交换周期的关系.结果显示,钦州湾的滞留时间为413 - 595 h,半交换周期为148 - 178 h,铁山港湾的滞留时间为215 - 598h,半交换周期约为50 h,钦州湾和铁山港湾的滞留时间均随径流量增大而减小.铁山港的滞留时间在小流量情况下随径流量的变化显著,在大流量下随径流量变化较小,而钦州湾的滞留时间随径流量大致呈线性变化.钦州湾和铁山港的滞留时间和半交换周期之间尚无明确的函数关系,这反映了不同海域的水深、地形及径流与潮汐相互作用的差异性和复杂性.

| Abstract: | In order to investigate the transport time scale in typical gulf substances in Guangxi, Atransport numerical model is established and applied in the Qinzhou Gulf and the Tieshan Gulf and theiradjacent areas. The residence time, semi-renewal period and their variation with different riverdischarges of these two gulfs are computed, meanwhile, the relationship between these two exchangetime scales is discussed. The results show that the residence time and semi-renewal periods are about413 - 595 h and 148 – 178 h respectively in the Qinzhou Gulf. The residence time in the Tieshan Gulfare about 215 – 598 h, and the semi-renewal periods are about 50 h. The residence time decrease asriver discharges increase. As river discharges change, the residence time in the Tieshan Gulf varysignificantly under small river runoff conditions, and vice versa. The residence time vary linearly withthe river discharge. No obvious functional relationship is revealed between the residence time andsemi-renewal period in the Tieshan Gulf and the Qinzhou Gulf. |
