景观水体中藻类水华的成因及药剂控制分析

Algae bloom-forming and algicide control in landscape water systems

在对影响景观水体中藻类生长规律的诸多环境因素,如营养物质、温度、光照、pH值及其它生物等因素进行介绍的基础上,结合景观水体的特点,详细分析了化学药剂和植物药剂对景观水体中藻类的控制作用。考虑到藻类控制的效果和对生态环境产生的影响,认为植物提取药剂和多种化学药剂复合使用对景观水体中藻类的控制有着很好的发展前景。

Combined with the characters of landscape water systems and based on introduction of environmental factors influencing the growth rhythm of algae, such as nutrients, temperature, illumination, pH, and other biological factors etc., the control actions of algae by using chemicals and galenicals was analyzed in detail. Considering the effect of algae control and the impact of ecological enviromnent, the galenicals and compound usage of several chemicals are believed to have a long term potential in control algae in landscape water systems.
