异位物理除藻对湖湾水体生境改善的试验研究

Experimental Research on Removing Algae by Ectopic Physical Method to Improve the Aquatic Environment in Lake Bay, Erhai Lake

针对大理市湾桥镇古生村北部洱海湖湾水动力差、蓝藻水华暴发几率较高的现状,研发完成以异位物理除藻的方式提升洱海水质、改善洱海周边生态环境、恢复该区域生物多样性群落等的除藻试验工程。文章就该项工程的试验内容、处理特点、藻类去除效果以及区域水体生境变化等进行了综述,并对其应用前景及可推广性进行了分折。

The aquatic dynamics near Gusheng village lake bay in Wanqiao Town, Northern Erhai Lake is not enough, which has resulted in a highly frequent emergence of blue algae blossom. Ectopic physical method was studied to remove algae in order to promote the water quality and nearby ecological environment and to restore the biodiversity of Erhai Lake. The experiment was introduced. The characteristics of the method and its removal effects were summarized as well as the changes of aquatic environment. The potential application of the method was proposed.
