广州市南湖近五年水质分析评价与保护探讨
|
摘要
南湖水域是首批国家级的旅游度假区,是白海面涌上游、白海面中央湿地公园的主要供水源头。文章根据南湖2014-2018年水质监测资料,按照《地表水环境质量标准》(GB3838-2002)的单因子评价法,并结合内梅罗污染指数综合评价法,来对南湖水质进行分析与评价。通过水质的评价分析为南湖水质治理提供科学依据、数据支撑与方法指引。结果表明:南湖水体主要污染物是总氮、总磷,水体处于轻污染或污染状态,水质类别为劣Ⅴ类。
The Nanhu Lake water areas in Guangzhou were the first national-level tourist resorts approved by the state, as well as they were also the main source of water supply for the upper reaches of the Baihaimian River and the Baihaimian Wetland Park. Therefore, this paper took the water quality monitoring data of Nanhu Lake from 2014 to 2018 as the starting point, along with in accordance with the single factor evaluation method of Surface Water Environmental Quality Standard(GB3838-2002), the water quality of Nanhu Lake was analyzed together with evaluated by combining Nemerow pollution index comprehensive evaluation method. Through water quality evaluation and analysis, it had provided a comprehensive scientific basis, data support and methodological guidance for water quality control of Nanhu Lake in Guangzhou. The results showed that the main pollutants causing water pollution of Nanhu Lake in Guangzhou were total nitrogen and total phosphorus, the water areas were in a light pollution or pollution state, as well as the water quality category was V, which represented inferior quality.
