  近40年来,在人类活动强烈干扰下,我国湖泊富营养化程度日益严重,一些湖泊蓝藻水华暴发常态化。蓝藻水华暴发,影响水体自然景观,降低水中溶解氧浓度、遮蔽阳光,影响水体中动植物生长,对人类饮水安全与人体健康造成影响。为解决此问题,国内外学者历经多年探索,己研究并使用了多种控制方法,包括物理法(生态调水、底泥疏浚、机械除藻、扬水筒、遮光控藻、超声波除藻、膜分离)、化学法(铜类药剂杀藻、铝、铁、钙类药剂捕藻、光敏计抑藻、除草剂抑藻)与生物法(化感作用)。本文评述了这些控制技术措施及研究进展,也介绍了蓝藻资源化利用(提取色素和多糖、制有机肥、产沼、制生物油、吸附重金属)技术的研究动态,以期为相关的研究提供参考。
