The seasonal variation of five selected multimetric indices for the determination of the Ecological Quality Status (EQS) of transitional waters was evaluated, as well as the indices' responses to an extreme drought event that occurred in 2005. The database used regards the Mondego River estuary, which was sampled from June 2003 to August 2006 on a monthly basis. Among the selected indices (EBI-Deegan et al.

The EQS by the several indices ranged from "Low" to "High", depending on the index considered, evidencing the high level of mismatch between indices. The results are discussed in the scope of the EU Water Framework Directive, regarding monitoring strategies, application of indices and EQS assessment.
评估了用于确定过渡水域生态质量状况（EQS）的五个选定多指标指数的季节变化，以及这些指数对2005年发生的极端干旱事件的响应。所使用的数据库涉及蒙德戈河河口，该河口于2003年6月至2006年8月每月进行采样。在选定的指数中（EBI - Deegan等人[Deegan, L., Finn, J.T., Ayvazlan, S.G., Ryder - Kieffer, C.A., Buonaccoesi, J., 1997. 河口生物完整性指数的开发与验证。河口30(3), 601 - 617]，EDI - Borja等人[Borja, A., Franco, J., Valencia, V., Bald, J., Muxika, I., Belzunce, M.J., Solaun, O., 2004. 从西班牙北部巴斯克地区实施欧洲水框架指令：一种方法学途径。海洋污染公报48(3 - 4), 209 - 218]，EFCI - Harrison和Whitfield[Harrison, T.D., Whitfield, A.K., 2004. 一种用于评估河口环境状况的多指标鱼类指数。鱼类生物学杂志65, 683 - 710]，EBI - Breine等人[Breine, J.J., Maes, J., Quataert, P., Van den Bergh, E., Simoens, I., Van Thuyne, G., Belpaire, C., 2007. 一种基于鱼类的佛兰德斯（比利时）斯海尔德河河口生态质量评估工具。水生生物学集刊575, 141 - 159]以及TFCI - Coates等人[Coates, S., Waugh, A., Anwar, A., Robson, M., 2007. 一种多指标鱼类指数作为水框架指令过渡性鱼类组成部分分析工具的有效性。海洋污染公报55, 225 - 240]），Breine等人（2007年）的EBI是唯一显示出明显年际和季节变化的指数。根据所考虑的指数不同，几个指数得出的EQS范围从“低”到“高”，这表明指数之间存在高度不匹配。在欧盟水框架指令的范围内，就监测策略、指数应用和EQS评估对结果进行了讨论。
