摘要:
文章选取13宗大中型水库，根据2021年水生态监测和调查成果，并结合历史情况，分析水库水质和营养状态，并进行蓝藻水华风险评估。结果显示，汛期6宗水库水质优于或达到Ⅱ类，非汛期7宗水库水质优于或达到Ⅱ类。2021年7宗水库的营养状态为中营养，6宗水库营养状态为轻度富营养。2021年藻类总丰度超过水华发生限值（1×107 ind/L）的水库有6宗。2010—2021年，发生过蓝藻水华的水库有9宗，尚未发生过蓝藻水华的水库有4宗。综合分析，2宗水库藻类水华发生风险等级为低，2宗水库水华发生风险等级为中，9宗水库藻类水华发生风险等级为高。
Abstract:
In this paper, 13 large and medium-sized reservoirs were selected to analyze the water quality and nutritional status of the reservoirs according to the results of water ecological monitoring and investigation in 2021, combined with the historical situation, and the risk assessment of cyanobacteria bloom was carried out. The results show that the water quality of 6 reservoirs in flood season is better than or up to Class II, and that of 7 reservoirs in non-flood season is better than or up to Class II. In 2021, the nutritive status of 7 reservoirs was medium nutrition, and the nutritive status of 6 reservoirs was mild eutrophic. In 2021, there were 6 reservoirs with total algae abundance exceeding the limit of bloom occurrence (1×107 ind/L). From 2010 to 2021, there were 9 reservoirs with cyanobacteria blooms and 4 reservoirs with no cyanobacteria blooms. Comprehensive analysis showed that the risk level of algal blooms in 2 reservoirs is low, the risk level of algal blooms in 2 reservoirs is medium, and the risk level of algal blooms in 9 reservoirs is high.
