哈希多参数水质监测仪DS5X在大宁河白水河段藻类研究的应用

Application of Hydrolad DS5X in Algae Research in Baishui Section of Daning River

采用哈希多参数水质监测仪DS5X选取大宁河白水河段进行垂直水柱藻类密度、水温、pH值、叶绿素a进行监测,发现藻类在水中随水深呈垂直分布且有减弱趋势,结果表明:水下5.0m以上藻类密度基本能反应水体中藻类的生长情况,藻类在水体中沉降,附着于底泥进入休眠、复苏阶段;蓝绿藻与水温、pH值、叶绿素a呈显著正相关关系。

The Hydrolad DS5X is used to monitor the vertical algae density, the water temperature, pH value, Chlorophyll A in Baishui section of Daning River. We find that the vertical distribution of algae is weakening with the depth of the water. The algae density with depth of above 5.0 m in the water could generally reflect the growth of the algae. They settle down on the sediment, and go through the dormancy and recovery. There is a remarkable positive correlation between the blue -green algae and the water temperature, pH value and Chlorophyll A.
