摘要
九龙江北溪下游是漳州、厦门地区主要饮用水源地。近年来,随着全球变暖以及各类污水排放量增加,该流域多次发生的水华事件,说明九龙江的水生态环境遭到破坏。本文通过回顾性研究藻类生长和流速的关系,提出了通过白沙水库放水,提高流域流速来抑制藻类生长的措施,控制藻类水华,保障流域供水安全。
The lower reaches of the north creek of Jiulong River are the main drinking water sources in Zhangzhou and Xiamen.With global warming and sewage discharge,water blooms have occurred many times in recent years,indicating that the water ecological environment of Jiulong River has been destroyed.Based on the retrospective study of the relationship between algae growth and water flow rate,this paper puts forward the measures to inhibit algae growth by releasing water from Baisha Reservoir and increasing the water flow rate,to control algae bloom and to ensure the safety of water supply in the basin.
