蓝绿藻的生态学研究进展

Study Progress on Cyanobacterial Ecology

在适宜的环境条件下,蓝绿藻在水中易形成水花,危害人群健康。各国学者对蓝绿藻进行过大量的生态学研究,近20年来的研究表明,蓝绿藻的生长和产毒,受光照、温度、氮磷、微量元素、溶解氧、叶绿素含量等多种环境因素的影响,这些因素的共同作用,导致了蓝绿藻生长及产毒水平的波动,也造成了水体中优势藻的季节性变化。

Under proper environmental conditions, cyanobacteria often form waterblooms which will make harmful to human health. World widely, lots of researchers have been studied the cyanobacterial ecology. This paper deeply introduced the relationship between the growth and toxin production of cyanobacteria and environmental factors for nearly 20 years. Lots of studies showed that the growth and toxin production of cyanobacteria were effected by kinds of environmental factors, such as light, temperature, nitrogen, phosphorus, trace elements, dissolved oxygen, chlorophyll a, which collaboration led to the vibration of the degree of the growth and toxin production of cyanobacteria and the seasonal variation of predominant algae strains in water body.
