摘　　要：随着社会经济的发展,城市周边的河流水体遭到不同程度的富营养化,随之而来的水华频繁发生,严重影响了水体功能,直接威胁人民的生活和身体健康。文章从水华的危害,成因,控制及防治几个方面进行了探讨,水体富营养化是水华发生的重要物质基础,生态失衡是水华发生的主要原因,生物生态治理是目前最优最可行的选择。水华的防治应该遵照生态系统理论,在控制外源污染的同时,努力恢复河流本身的生态系统,实行常规治理措施和生态治理措施相结合的方法,协调人与自然生态之间的关系。With the development of society and economy growth, the river water around the city were suffer from different degrees of water eutrophication, and with water bloom frequent, it seriously affected the water basic function and threaded to people＇s life and health. The study went about the harm of water bloom, causing, controlling and prevention. The nutrients is the important material base of water bloom, and the ecological imbalance is the main cause of water bloom, and the bio-ecological management is the optimal choice of the most practical. It should be controlled by the theory of the ecological system, and to regain the river ecological system with controlling foreign contaminant, combining the conventional management measures and ecological managements at the same time, reflects the harmony of man and nature.
