Phytoplankton 2015

Phytoplancon is one of the 4 biological quality elements (BQE) for the assessment of the ecological status of the natural water bodies. The evaluation of this BQE is only relevant for the large rivers where the quantity of phytoplancton is significant and can be evaluated. The natural water bodies of typology VI present significant phytoplancton concentrations to allow an assessment. Some of the heavy modified waterbodies (HMWB) present significant phytoplancton concentrations too, these are the HMWB Sûre (WB III-2.2.1) and the HMWB Our (WB V-1.2). The annual frequency for phytoplancton monitoring is 6 samples between April and October.

浮游植物（Phytoplankton）是评估天然水体生态状况的4项生物学质量要素（biological quality element, BQE）之一。该生物学质量要素的评估仅适用于浮游植物量充足且可开展监测评估的大型河流。类型VI的天然水体具备可用于评估的显著浮游植物浓度。部分重度改造水体（heavy modified waterbody, HMWB）同样拥有可观的浮游植物浓度，具体为叙尔河重度改造水体（WB III-2.2.1）与乌尔河重度改造水体（WB V-1.2）。浮游植物监测的年度采样频次为4月至10月间采集6份样品。
