内蒙古乌梁素海“黄苔”暴发初探及防治对策

内蒙古乌梁素海分别于2008年5月和2009年5月连续2年暴发了"黄苔"事件,已不断丧失湖泊固有的养殖、灌溉、旅游等功能,严重制约着区域经济的可持续发展。乌梁素海水体富营养化程度的加剧已引起国务院领导和各界学者的关注。根据乌梁素海试验站实际监测的数据,对"黄苔"暴发期前后的水质、水文、气象等因素进行分析,以揭示影响"黄苔"暴发的环境、营养盐、水动力等条件。研究结果表明:乌梁素海"黄苔"的暴发主要是水体长期处于富营养化状态和适宜"黄苔"生长的各种条件共同作用的结果。系统科学地研究"黄苔"暴发的原因能够为乌梁素海"黄苔"暴发的预警、防治提供一定的依据。
