摘　　要：水网藻水华在国外出现较多,在国内鲜有报道.2013年5月对鄱阳湖进行采样时首次发现水网藻水华;结合现场观测及遥感影像确定其分布范围为老爷庙至落星墩水域,分布面积约为26 hm2,推测水网藻可能是由上游稻田等静止水体迁移至鄱阳湖,在相对静水区进行聚集生长,加上合适的理化条件(温度及营养盐),从而形成水华.在此基础上,本文进一步分析了水网藻水华对鄱阳湖水生态环境可能产生的影响.Hydrodictyon reticulatum blooms, which were common in the overseas, were rare in China. This study reported, first time in China, the Hydrodictyon reticulatum bloom in Lake Poyang. It spread over the area between the Laoye Temple and Luoxing- dun in Xingzi County, and covered an area of about 26 ha, based on remote sensing image. It was hypothesized that Hydrodictyon reticulatum was migrated from paddy and other lentic waters, grew quickly under relatively favorable conditions. In addition, with enough nutrients, Hydrodictyon reticulatum bloom could happen again in Lake Poyang. This study preliminarily illustrated the bloom＇ s potential ecological impacts on Lake Poyang.
