辽东湾北岸主要入海河流污染物入海通量及其影响因素分析
Analysis of major pollutants flux into the sea and influencing factors on the north shore of the Liaodong Gulf

摘要: 利用辽河、大辽河、小凌河1992-1995,2004-2007年,大凌河1995-2007年的水文和水质入海监测资料,估算了辽东湾北岸四条主要入海河流各污染因子的入海通量,并初步分析了污染物通量年际变化的影响因素。结果表明,辽东湾北岸的四条主要河流中除小凌河各种污染物入海通量总体上呈增加趋势以外,其他三条河流各污染物的入海通量总体上都呈减小趋势。污染物入海通量的变化主要受入海径流量的影响,同时也与各流域的社会经济发展密切相关。

Abstract: Based on the data of hydrology and water quality of the Xiaoling River (1992-1995, 2004-2007), the Daling River, the Liaohe River and the Daliao River (1995-2007), pollutant fluxes of the four major rivers discharged into the sea on the north shore of the Liaodong Gulf, were preliminarily analyzed.The results indicate that besides the Xiaoling River, the pollutants flux trend of the other three rivers into the sea basically increases.The change of pollutants flux into the sea is mainly affected by the river runoff, and the specific situation of economic development and industrial structure in the watershed of each river.-
