| 摘 要： | 对银川市景观水道(艾依河)浮游植物群落组成特征,水体TN、TP、COD、叶绿素a、透明度等指标进行时空动态监测;结合国内外常用的生物指数、多样性指数及营养状态指数等方法,对水体营养状态进行综合评价。结果表明:景观水道共发现藻类115种,夏季为绿藻-蓝藻型,秋季为绿藻-硅藻-蓝藻型;两季平均绿藻指数6.2,藻类综合指数10.9;Margalef指数平均2.69,Shannon-Weaver指数平均0.82;各站点营养状态指数均值为72.63。综合分析得出:景观水道水体处于富营养化状态,并有继续恶化的趋势,个别站点已达到极富营养化水平。

| Abstract: | The phytoplankton constitutional characteristics,total N,total P,COD,chlorophyll a,and transparency of Yinchuan landscape canal were inspected dynamically.Biological index,diversity index and nutrition state index were applied to evaluate the nutrition state of the canal.The results showed that the total alga types,which was green-blue alage types in the summer,but was green-diatom-blue alage types in the autumn,was 115.The average green alga index in the two seasons was 6.2,integtate index was 10.9,Mamarga... |
