摘要
对2007—2016年山东省主要流域、湖泊水环境质量状况进行时空变化趋势分析。结果表明:2007—2016年山东省水环境质量呈好转趋势,但总体状况仍令人堪忧;化学需氧量平均浓度由60.20mg/L降为23.10mg/L,未达到地表水环境质量Ⅲ类水质标准;五大流域和“四湖”水质污染状况严重,小清河流域仍未消除劣Ⅴ类水体,“四湖”富营养化现象较重;潍坊、临沂、菏泽、泰安等地市主要污染物排放量巨大,成为山东省水环境主要污染物的贡献者。
The water environmental quality of big rivers and lakes in Shandong province and the spatial and temporal distribution of major pollutants were studied from 2007 to 2016.The spatial and temporal variation trends of water environment quality were analyzed.The results showed that the water environment quality of Shandong province has been improving from 2007 to 2016,but overall situation was still worrying.The average concentration of COD for the surface water was decreased from 60.20 mg/Lto 23.10 mg/L,which has not yet reached the class Ⅲ water quality standard.The water pollution of the five rivers and the Four-lake was serious.The water quality of the Xiaoqing River basin was worse than the classⅤ.Theassessment of the presenteutrophicationstatusindicated that the Four-lake of Shandong province was undereutrophication condition.The emissions of major pollutants were huge in Weifang,Linyi,Heze,and Taian City,which were the main contributors of water pollution for Shandong province.
