摘要
2009年9月对津河设置了13个取样点,进行采样,根据水体理化指标对津河水质状况进行了生物学评价,并依据总磷(TP)、总氮(TN)、透明度(SD)、高锰酸盐指数(CODMn)、叶绿素a(chla)综合评价水体的营养状态。结果表明,目前津河总氮、总磷、化学需氧量等主要指标均超标,整体处于重度富营养化状态。分析了津河富营养化的主要成因,并提出了保护津河水质的相关措施及建议。
In September 2009,13 sampling stations were selected at Jinhe River,the water quality status of the Jinhe River were assessed according to physical and chemical indicators,and based on total phosphorus（TP）,total nitrogen（TN）,transparency（SD）,potassium permanganate index（CODMn）,chlorophyll a（chla） we conduct comprehensive evaluation of the nutritional status of water bodies.The results showed that： Jinhe River was in severe eutrophication of the state as a whole.The main causes of eutrophication in Jinhe River were analyzed and proper measures and recommendations were given.
