Biological Investigation Programme 2007-2016

According to the Quality Target Ordinance Ecology Surface Waters (BGBl. II No 99/2010 idgF), the biological quality components Phytobenthos (PHB) are simplified (simplified: Algae) and benthic invertebrates (macrozoobenthos, MZB) (simplified: invertebrates inhabiting the water floor alongside the fish fauna and macrophytes (simplified: higher aquatic plants) used to determine the ecological status of surface waters. They have high significance especially with regard to the material load and therefore serve to determine the biological state with regard to material stress. The results of sampling from 2007 to 2016 at Upper Austrian flowing waters — sampling points of the Biological Investigation Programme (BUP) — are displayed. The assessment is carried out via an assignment to one of the 5 status classes: very good, good, moderate, unsatisfactory, bad; The given environmental objective is to achieve or maintain at least the status class.根据《生态地表水质量目标条例》（BGBl. II No 99/2010 idgF），用于测定地表水生态状况的生物质量组分包括底栖藻类（Phytobenthos, PHB，简化表述为藻类）、底栖无脊椎动物（大型底栖无脊椎动物，macrozoobenthos, MZB，简化表述为栖息于水底的无脊椎动物），以及鱼类群落和大型水生植物（macrophytes，简化表述为高等水生植物）。 上述组分对物质负荷具有极高的指示意义，因此可用于评估物质胁迫下的生物状态。 本数据集展示了2007年至2016年间，对上奥地利地区流动水体（隶属于生物调查计划（Biological Investigation Programme, BUP）的采样点位）的采样结果。 本次评估通过将结果划分为5个生态等级类别完成：极佳、良好、中等、不合格、极差；既定环境目标为达到或维持至少该等级类别的生态状况。
