摘要:
以太湖湖体中沙清、兰山嘴两个自动站的监测数据为基础,分析了太湖蓝藻爆发过程中主要水质指标变化情况。研究结果表明,蓝藻引发灾害性湖泛现象的主要过程分为生长期、平稳期、死亡期、高危前期、灾害期和恢复期,在高危前期和灾害期,溶解氧(DO)快速下降,而总氮(TN)等参数的变化正好与DO变化相反,这一显著特征可作为预警的重要信息。

Abstract:
The water quality index was analysed during blue green algae outbreak in Taihu Lake based on the data from two au- tomatic monitoring stations, Sbazhu and Lanshanzui. The results showed that blue green algae in the lake caused the main process was divided into growth period, steady period, death period, pre-disaster period, disaster period and recovery period. DO rapidly declined, while the change of total nitrogen (TN) and other parameters was opposite to that of DO in the disaster period. It is im- portant information for early-warning.
