大辽河口典型污染物时空分布研究

摘要

Based on the four times survey data from 2009 to 2010, spatial and time distribution of typical contami-nants of Daliaohe estuary was analyzed. The results show that nitrogen pollution is the most important problem of river segment and offshore segment in Daliaohe Estuary.%基于2009—2010年的4次调查数据，对大辽河口河流段与近海区典型污染物浓度的时空分布特征进行了分析研究。结果表明，大辽河口河流段与近海区均以氮污染问题最为突出。
