蓝藻可以在各种水体中出现,尤其适于有机物丰富,碱性较高(pH8—9.5)的水体中,当水温较高(25—30℃)的季节里繁殖快,有时大量发生,有些种类还可形成湖靛。湖靛又称水花或水华。但在江浙一些地区称为浮靛、臭绿沙等;在安徽地区称湖青、湖片、湖淀等;广东俗称(艹耗)等。它主要分布于长江中下游、云贵高原和东北平原等一些湖泊中,
Cyanobacteria can occur in a variety of water bodies, especially for water rich in organic matter with high alkalinity (pH8-9.5). When the water temperature is higher (25-30 ℃), the cyanobacteria multiply rapidly and sometimes occur in large quantities. Some species Can also form lake indigo. Lake indigo also known as water or bloom. But in some areas of Jiangsu and Zhejiang called floating indigo, smelly green sand, etc .; in Anhui area called lakes, lakes, lake, etc .; Guangdong commonly known as (consumption) and so on. It is mainly distributed in the middle and lower reaches of the Yangtze River, Yunnan-Guizhou Plateau and some lakes in the Northeast Plain,
