摘　　要：为客观评价丹江口水库的水质,在库区选择了习家店和神定河2个实验区,对水体进行采样分析。分析结果表明:总体看来,丹江口水库水体富营养化状况较轻,绝大部分为中营养化状况;典型支流和库湾在特定的时段内为富营养化状况,习家店富营养化状况居中,神定河富营养化状况较严重;从年内时间分布来看,夏季水体富营养化状况均较秋季严重;从年际时间分布来看,2011年水体富营养化状况轻于2010年同期水平。In order to objectively assess the water quality of Danjiangkou Reservoir,2 experimental zones of Xijiadian and Shending River in the reservoir area are selected for water sampling and analysis.The analysis results show that in general,the water quality of Danjiangkou Reservoir is good,most of the area is in mesotrophication;in special periods,eutrophication occurs in typical bays and tributaries,the eutrophication of Xijiadian zone is in moderate,but the Shending River is comparably serious;the eutrophication in summer is more serious than that in autumn;the water eutrophication in 2011 is lighter than that in 2010.
