摘要
酸碱平衡失调是渔洞水库水生生态系统失衡的具体表现形式。文章立足工作实际,分析渔洞水库pH值异常变化成因,藻类的生长与N、P的联系,pH值异常变化与藻类优势种群的出现以及藻类与富营养化之间的关系,鲢鱼、鳙鱼控藻利弊。分析认为:保护好渔洞水库水资源需要在水环境的保护上建立长效机制,在水量和水质方面认真、彻底做好相关的工作,切实把预防突发性水污染事件放在突出位置,把有效去除N、P等(特别是P)营养物质,有效遏制水体富营养化的发展作为根本性任务。
Acid -base balance disorder in Yudong Reservoir manifested its aquatic ecosystem imbal- ance. This paper analyzed the cause of pH abnormal change, demonstrated the relationship between the growth of algae and N and P level, pH abnormal change and dominant populations of algae, algae and eutrophication, also it discussed the pros and cons of using silver carp and bighead carp fish to control algae growth. It pointed out that, in order to protect Yudong Reservior, we should establish a long - term mechanism on the protection of the water environment, put the prevention of water pollu- tion accident in a prominent position, and take the effective removal of N, P, and other (especially P) nutrients and curbing eutrophication development as the fundamental task.
