Comprehensive Assessment and Analysis of Water Environmental Quality in the Mainstream of the Liaohe River
摘要
Abstract
[Objective ] The study aims at evaluating the water environmental quality of the Liaohe River mainstream. [ Method ] Water quality of two monitored sections in the mainstream of the Liaohe River from 2004 to 2010 was assessed by the fuzzy comprehensive appraisal combined with weighted average, and Rome practicable measures were put forward according to the assessment results. [ Result] From 2004 to 2010, the water quality of the Liaohe River mainstream varied from Grade II to III at Zhuershan section, and changed from Grade II to IV at Xing1 an section, becoming better on the whole. \n addition, the major factor influencing the water quality is the small content of dissolved oxygen (DO) in the water body. Meanwhile, the pollution of the water body mainly results from the discharge of organic matter consuming oxygen largely, and ammonia nitrogen should be paid more attention to. [Conclusion] The research could provide scientific references for the protection pollution control and water environment in the mainstream of the Liaohe River.关键词
