摘要
北山湖属于小型景观水体具有自净能力差、容易产生水体富营养化的特点.于2015年4月(枯水期)对北山湖水体进行了叶绿素a(CHl-a)、总磷(TP)、总氮(TN)、透明度(SD)、高锰酸盐指数(CODMn)等理化因子测定;分析北山湖水质现状.结果表明:春季北山湖的水体中度富营养化,富营养化等级达到Ⅳ级.
Beishan lake belongs small-sized landscape water, its? self purification ability is poor and easy to bring water eutrophication. In April 2015 (the dry season ), people determined the water of Beishan lake, including chiorophy11-a, total, phosphorus, total nitrogen, transparent, permanganate index, and other physical and chemical factors.It results showed that the water of Beishan lake had severe eutrophication and the safety grade to grade Ⅳ.
