Monitoring biotic factors is gaining in importance within Europe, due in large extent to the ecological approach of the European Water Framework Directive (WFD) and the importance attributed to biological elements in the assessment of quality status. Despite its ecological importance, the Lima Estuary is subjected to a range of perturbations, including urban, agricultural and industrial waste discharge, dredging activities, and introduction of non-indigenous invasive species. This work uses macrozoobenthic data to study the ecological status of the lower Lima Estuary where most disturbance factors are concentrated. We were able to verify consistent differences along space, and to identify different degrees of disturbance in the estuarine area. These results allow us to suggest cost-effective approaches to monitor this estuarine area, aiming on contributing to effective management actions.
监测生物因素在欧洲变得越来越重要，这在很大程度上是由于欧洲水框架指令（WFD）的生态方法以及在水质状况评估中对生物因素的重视。尽管利马河口具有重要的生态意义，但它仍受到一系列干扰，包括城市、农业和工业废物排放、疏浚活动以及引入非本地入侵物种。本研究利用大型底栖动物数据来研究位于利马河口下游的生态状况，该区域集中了大多数干扰因素。我们能够验证空间上的一致性差异，并确定河口区域的不同干扰程度。这些结果使我们能够提出具有成本效益的监测该河口区域的方法，旨在为有效的管理措施做出贡献。
