摘要
太湖藻类的爆发呈现一定的阶段性,根据2008年太湖藻类的时空分布,将藻类爆发划分为5个阶段。在太湖流域藻类预警应急监测期间,连续监测湖州市新塘港与太湖交界断面的8项水质指标,研究藻类爆发不同阶段交界断面水质指标的变化情况,采用Pearson相关分析法分析各水质指标间的相关性,探讨不同时期太湖流域藻类预警应急监测应重点关注的水质指标,为浙江省太湖流域藻类防控提供理论依据。
The algae bloom in Tai Lake exhibited stage characteristics, according to the spatial distribution of algae in 2008, the author divided algae bloom into five stages. 8 water indexes in transition section of Tai Lake and New Port during algae outbreak were monitored in the algae early-warning monitoring. The variation of river water quality during different stages of algae bloom was studied, and the correlations among the 8 water indexes were ana- lyzed by Pearson correlation analysis. Base on the stage characteristics of algae bloom, early-warning monitoring should focus on different indexes in different stage, which provided theoretical basis for prevention and control of algae in Tai Basin, Zhejiang.
