| 摘 要： | 文章分析秦皇岛4个海水浴场6个监测站位2015—2018年采集水质样品中粪大肠菌群和溶解氧的变化趋势,并结合《海水水质标准》和《海滨浴场游泳适宜度分级规定》,对4个浴场的水质进行分析评价。结果表明:粪大肠菌群是海水浴场的主要污染物,粪大肠菌群浓度的变化主要受降雨、游客数量、温度和陆源污染物影响。尤其强降雨后,粪大肠菌群浓度升高较明显。浴场的溶解氧含量变化不大,年均值均满足二类水质标准,其主要受水温和浮游生物等因素影响,高峰值多出现在9月和10月。秦皇岛4个海水浴场的水质优良状况表现为南戴河浴场最好、东山浴场和北戴河浴场次之、西浴场最差。

| Abstract: | In this study, the change trends of fecal coliforms and dissolved oxygen in water quality samples, collected from the six monitoring stations of the four bathing beaches from 2015 to 2018 in Qinhuangdao, were analyzed, combining the Sea Water Quality Standard and Beach Rules for the Classification of Swimming Suitability in Bathing Beaches, thus giving analysis and evaluation of the water quality of the four baths. The results are as follows: fecal coliforms are the main pollutants of bathing beaches. Changes in the concentration of fecal coliforms are mainly affected by rainfall, number of tourists, temperature and land based pollutants. Especially after heavy rainfall, the concentration of fecal coliforms increased significantly. The dissolved oxygen content of the bathing beach had little change, and the annual average value satisfied the second class water quality standards, which is mainly affected by factors such as sea surface temperature and plankton. The peaks mostly occurred in September and October. The water quality in Nandaihe Bathing Beach is the best of the four beaches in Qinhuangdao, followed by Dongshan Bathing Beach and Beidaihe Bathing Beach, and West Bathing Beach is the worst. |
