The aim of this study is to develop a new method for classification of marine benthic quality according to the European Union Water Framework Directive. Tolerance values to environmental disturbance were determined in an objective analysis for benthic species along the Swedish west coast by using 4676 samples from 257 stations. Based on a combination of the species tolerance values, abundance and diversity, a benthic quality index (BQI) was calculated for the assessment of environmental status at a particular station. The qualification of BQI was evaluated in relation to known spatial and temporal gradients of disturbance.
本研究的目的是根据欧盟水框架指令开发一种新的海洋底栖生物质量分类方法。通过使用来自257个站点的4676个样本，对瑞典西海岸底栖生物物种进行客观分析，确定了对环境干扰的耐受值。基于物种耐受值、丰度和多样性的综合考量，计算了底栖生物质量指数（BQI），用于评估特定站点的环境状况。根据已知的干扰空间和时间梯度对BQI的合格性进行了评估。
