摘要
对湘江流域湘潭段2001—2010年近10年来氨氮的污染状况、变化趋势、污染原因等进行分析。结果表明:2001—2010年,湘江湘潭段的氨氮污染虽有起伏变化,但仍呈显著上升趋势,2007年发展至顶峰,随后逐年下降;涟水湘潭段的氨氮污染值自2006年起呈不显著下降趋势;从2008年开始湘江流域湘潭段氨氮年均值未再超标。
The comprehensive analysis was made to the pollution of ammonia-nitrogen in Xiangjiang River basin of pollution condition and change trend in the latest 10 years. The results show that the pollution of ammonia- nitrogen in Xiangjiang River basin despite ups and downs rise trend ,but still has significant changes 07 development to peak,then gradually decreased; Ammonia-nitrogen pollution in Xiangtan Section of Lianshui River were not significant decline since 2006; Ammonia-nitrogen pollution in Xiangtan section of Xiangjiang River basin average not to exceed bid since 2008.
