摘　　要：采用水质综合标识指数法对某水体2012年全年水质污染特征进行分析。结果表明,该水体各断面水质基本达标;空间分布上水质从上游到下游呈下降趋势,时间分布上丰水期水质与枯水期水质相比基本无差异;CODMn是该水体的主要特征污染物,非点源是主要污染来源。The annual water quality contamination characteristics of one river basin were analyzed in 2012 by the comprehensive water quality identification index method.The results showed that the water quality in each section could basically reach the standards,and the water quality was decreased from upstream to downstream for the spatial distribution.The water quality was similar in dry season and in flood season for the temporal distribution,the CODMnwas the main characteristic contaminant in the waters,and the main contaminants were from the non-point sources.
