摘要:
根据2016—2020年珠海市金湾区集中式饮用水水源地的监测数据,采用单因子评价法、综合污染指数法和综合营养状态指数法对金湾区黄绿背水库、爱国水库和木头冲水库环境质量变化趋势及特征进行分析评价。结果表明,2016年3个水库的综合污染指数最高,水质最差,超标因子为总磷,除了2016年黄绿背水库超出《地表水环境质量标准》(GB 3838—2002)Ⅲ类标准外,其他年份和其他水库水质均达相应水功能区标准;2016—2020年3个水库水质总体呈好转趋势,但改善趋势不显著,影响水质的主要因子为溶解氧、总磷、化学需氧量和五日生化需氧量;3个水库水质的综合营养状态指数在10~24范围内,均处于贫营养状态,未呈现富营养化。

Abstract:
Based on the monitoring data of centralized drinking water source acquired form 2016 to 2020 in Jinwan District, the single factor index evaluation method, comprehensive pollution index method and comprehensive nutritional status index method were used to analyze the variation characteristics and variation trends of water quality of huanglvbei reservoir, aiguo reservoir and mutouchong reservoir. The results showed that the comprehensive pollution index of the three reservoirs reached the highest and the water quality were the worst in 2016, and total phosphorus was the main impact factor. Except the water quality of huanglvbei reservoir exceeded the class Ⅲ standard of surface water environment quality (GB 3838—2002) in 2016, other reservoirs water quality all met the demands of standard. During 2016—2020, the water quality of the three water sources showed an overall improving trend, while the trend was not significant. The main factors were dissolved oxygen, total phosphorus, chemical oxygen demand and five days biochemical oxygen demand. The comprehensive nutritional status indexes of the three water sources were in the range of 10~24, and all of them were in the state of oligotrophication, not eutrophication.
