摘要
藻类在生长过程中,主要受光照、温度、营养盐及水动力条件等环境因子的影响。以往很多对藻类生长过程中的影响因子分析,主要通过试验方法获取。利用美国环保局开发的AQUATOX模型,以团城湖调节池为研究对象,选择南水北调北京段的2种优势藻种——针杆藻和小环藻,应用数值模拟方法,分析了温度、风速、水动力条件和营养盐等因子对藻类生长的影响。研究成果可为团城湖调节池水质保护对策的制定提供依据。
Algae growth is usually influenced by environmental factors, such as illumination, temperature, nutrient salt and hydrodynamic condition. In the past research, the influence factors of algae growth were analyzed mainly by experimental methods. In this paper, the author analyzed influence factors, such as temperature, wind speed, hydrodynamic conditions and nutrient salts by numerical simulation using AQUATOX model developed by Environmental Protection Agency of U.S.A.. Synedra and Cyclotella were selected as dominant algaes in the Tuanchenghu adjusting pool transferred from the middle line of the south-to-north water transfer project. The results could be used to make some countermeasures for protecting water quality of Tuanchenghu adjusting pool.
