摘　　要：[目的]研究太湖流域不同季节水体富营养化情况。[方法]以5个位于太湖流域不同重要河流断面和1个湖体的自动站的一年监测数据为基础,监测并分析太湖流域中氨氮、总氮含量以及比值在不同季节的变化情况。[结果]季节对太湖流域的氨氮、总氮含量具有显著性影响。其中,冬季太湖流域中氨氮、总氮含量显著高于其他季节的太湖流域中氨氮、总氮含量,且太湖流域的总氮含量在夏秋季节最低。同时,太湖流域的氨氮和总氮含量比值在不同季节亦表现出显著性差异。[结论]该研究可为太湖水体富营养化以及蓝藻水华治理提供一定科学依据。[Objective] The research aimed to study the water eutrophication situation of Taihu Lake Basin.[Method] Based on the one year monitoring datas from 5 automatic monitoring stations which located in different important Taihu rivers and 1 automatic monitoring station which located in lake,the NH3-N,TN and their ratio of Taihu Lake Basin in different seasons was monitored and analyzed.[Result] The results showed that season had significant impact on the NH3-N and TN of Taihu Lake Basin.The NH3-N and TN of Taihu Lake Basin in winter were significantly higher than those in other seasons,and the TN of Taihu Lake Basin in the summer and autumn were lower.At the same time,ratio of the NH3-N and TN of Taihu Lake Basin in different seasons were significantly different.[Conclusion] This study could provide scientific basis for the control of water eutrophication and cyanobacterial bloom in Taihu Lake Basin.
