浦城东风水库水华情况调查和防控措施

Investigation and prevention and control measures of blooms in Dongfeng Reservoir of Pucheng

水华是藻类在富营养化水体中大量繁殖的常见自然现象,是集环境、气象、水文和生物等多种因素相互作用的结果 ,存在季节性的特征。本文对2021—2022年东风水库水华易发期的藻类群落结构、密度变化和水华暴发的原因进行了调查分析,并提出了水华防控的建议,为该水库的管理和饮用水安全提供理论依据和可行措施。做到防范化解生态环境风险,推进源头治理、标本兼治。

Water blooms are common natural phenomena of massive algal proliferation in eutrophic water bodies.They are the result of interactions between multiple factors including environment,climate,hydrology and biology,with seasonal characteristics.This paper investigated the algal community structure,density changes during the susceptible period of water blooms from 2021 to 2022 in Dongfeng Reservoir,and analyzed the causes of water bloom outbreaks.Control recommendations were proposed to provide theoretical basis and feasible measures for reservoir management and drinking water safety.The goals are to prevent and resolve ecological and environmental risks through source control and integrated measures.
