摘　　要：为探究适用于义乌市富营养化水体的藻华监测方案,调研了义乌市具有代表性的岩口水库和义乌江的常规水质指标,分析了义乌市水体藻华暴发的问题现状和影响因素,并结合现有的藻华监测方法,筛选了适合义乌市的藻华监测方法。结果表明:水温、营养盐和水动力等因素均可显著影响富营养化水体的藻华暴发;现场监测、实验室分析、遥感监测和在线监测均可适用于义乌市不同类型富营养化水体的藻华监测。总体监测方案建议是以在线监测作为主体,辅之以现场巡视和实验室分析,并定期对监测数据进行校核。To explore the monitoring scheme of algal blooms suitable for eutrophication water bodies in Yiwu City, the problem status and influencing factors of algal blooms were analyzed by monitoring the water quality indicators of the representative water bodies(Yankou Reservoir and Yiwu River). Considering the existing algal blooms monitoring methods, the algal blooms monitoring methods suitable for Yiwu City were proposed. The results showed that water temperature, nutrient salt and hydrodynamics could significantly affect the growth of algal blooms in eutrophic water body. In-site monitoring, laboratory analysis,remote sensing and online monitoring could be performed for the algal bloom monitoring of different types of eutrophic water bodies in Yiwu. The overall monitoring scheme was proposed that the online monitoring was the main method with additional site inspections and laboratory analysis, and the monitoring data should be regularly checked.
