三峡水库2011年上半年在大宁河支流白水河发生了以绿藻为主的“水华”，用DS5x便携式多参数水质测定仪进行了现场监测。通过分析发现溶解氧、pH、PCY、叶绿素4项指标成正相关的关系，在水柱监测中发现水温、溶解氧、pH、PCY、叶绿素5项指标从水面往下是递减，且5m以下趋于稳定。基于此，建议今后在水华应急监测中可以直接用现场监测指标来判断水华的严重程度。
三峽水庫2011年上半年在大寧河支流白水河髮生瞭以綠藻為主的“水華”，用DS5x便攜式多參數水質測定儀進行瞭現場鑑測。通過分析髮現溶解氧、pH、PCY、葉綠素4項指標成正相關的關繫，在水柱鑑測中髮現水溫、溶解氧、pH、PCY、葉綠素5項指標從水麵往下是遞減，且5m以下趨于穩定。基于此，建議今後在水華應急鑑測中可以直接用現場鑑測指標來判斷水華的嚴重程度。

The green algae bloom was seen in Baishui River, a tributary of Daning River of the Three Gorges Reservoir in the first half year of 2011. The on -site monitoring was carried out with the DSSx portable multi -parameter water quality Detector. The analysis shows that there is a positive correlation between DO, pH, PCY and chlorophyll. The monitoring of the water column shows that the water temperature, DO, pH, PCY and chlorophyll are declining until reaching a depth of 5 meters. Therefore, it is suggested to take the on - site monitoring indexes to determine the severity of algal bloom during its emergency monitoring.
