A set of methodological tools was tested to assess the sensitivity of several ecological and biological indices to eutrophication while at the same time attempting to explore a linkage among pressures, classification assessment and drivers. Industrial discharges, harbor activities, natural interactions and river discharges are the pressures most related to the eutrophication process in tropical coastal water bodies. Among the eutrophication indices used, TRIX and operational indicators overestimated the eutrophication status in the study area, but EI and chl-a seems to be a rather responsive index to reflect the first stage of eutrophication. It is noteworthy that EI and chl-a showed better overall agreement with the ecological quality status (EcoQ) showing that probably it reflects the indirect relation of macrobenthic with water eutrophication in a better way. An ecological boundary of EI and chl-a from moderate to poor may be needed in order to explain the poor status of relatively eutrophic Klang Strait coastal sites.

热带沿海水域富营养化的现状和特征

测试了一套方法工具，以评估几种生态和生物指标对富营养化的敏感性，同时尝试探索压力，分类评估和驱动因素之间的联系。工业排放，港口活动，自然相互作用和河流排放是与热带沿海水域富营养化过程最相关的压力。在使用的富营养化指标中，TRIX和操作指标高估了研究区的富营养化状况，但是EI和chl-a似乎是反映富营养化第一阶段的响应度较高的指标。值得注意的是，EI和chl-a与生态质量状况（EcoQ）表现出更好的总体一致性，表明它可能以更好的方式反映了大型底栖动物与水富营养化之间的间接关系。为了解释相对富营养的巴生海峡沿岸地区的状况不佳，可能需要EI和chl-a的生态边界从中度到较差。
