水库蓝藻生态治理措施及效果评估

Ecological Treatment of Cyanobacteria in Reservoir and Its Effectiveness Evaluation

蓝藻爆发会加剧水生态系统的失衡,直接威胁到居民的用水安全。以我国江西省寻乌县九曲湾水库为例,在分析其蓝藻爆发成因机制的基础上,系统介绍了水库蓝藻水华的生态治理措施,重点分析了生态治理措施对水质、水生动植物等水生态指标的治理效果。结果表明,生态治理措施在控制九曲湾水库蓝藻水华和水体富营养化,以及优化水生态系统中发挥了积极作用,取得了较为理想的生态效应。

The outbreak of cyanobacteria exacerbates the imbalance of water ecosystem and directly threatens the water security of resi- dents. Taking Jiuquwan Reservoir in Xunwu county, Jiangxi province for an example, based on the situation of reservoir and the mechanism of cyanobacteria outbreak, the ecological treatment of cyanobacteria is systematically introduced. Furthermore, the effects of ecological treatment on water quality, aquatic animals and plants and other water ecological indicators are analyzed. The result shows that ecological treatment plays an active role in controlling the outbreak of cyanobacteria and the eutrophication of water body, and optimizing water ecosystem.
