库区蓄水后大宁河神女溪富营养化调查与评价
Investigation and Assessment of Eutrophication of Shennv River and Daning River in Sanxia Reservoir after Water Storage
【摘要】 2003年9月至2004年8月分别对大宁河与神女溪回水段水体进行了富营养化调查和监测,监测项目SD、TN、TP、CODMn和chla。并运用综合营养状态指数法对监测结果进行了评价与分析,结果表明三峡蓄水为富营养化的发生提供了更有利的条件,在可预测的未来,富营养化有加重的可能。
【Abstract】 Investigation and assessment of eutrophication of Shennv river and Daning river in Sanxia reservoir have been finished from September of 2003 to August of 2004,the monitoring indexes include SD,TN,TP,CODmn,and Ch/a.The results gotten by comprehensive method of index of nutrition show that water storage provides better conditions for the occurrence of eutrophication,and there will be serious eutrophication in the future.
