摘　　要：为分析滨州市近岸海域水质与潮河总氮之间的关系,本研究开展了2022年6月至2023年5月潮河入海口近岸海域海水污染物分析,海水无机氮浓度与潮河贾家、邵家总氮浓度、潮河总氮排海量分析。结果表明:1)海水无机氮浓度在一年中变化较大,无机氮浓度在7月、8月和9月最高,水质不能满足海水优良水体要求。无机氮浓度主要受硝酸盐氮影响,在7月、8月和9月硝酸盐氮分别占无机氮的84%、89.7%和82%;2)潮河贾家、邵家断面总氮浓度最低出现在汛期雨季,近岸海域无机氮浓度与潮河贾家、邵家总氮相关系数r分别为-0.797、-0.785,为负相关性,这与汛期雨季潮河水量增大有关;3)近岸海域无机氮浓度与潮河总氮排海量呈大致相同的变化趋势,海水中无机氮浓度受总氮排海量影响较明显。贾家总氮排放量高是导致总氮排海量高的主要原因,总氮排海量受水流量控制。In order to analyze the relationship between the water quality of the coastal waters of Binzhou and the total nitrogen in the water quality of the Chao River,the study focuses on the seawater pollutants found in the Chao River Estuary coastal waters between June 2022 and May 2023.The research analyzed the levels of inorganic nitrogen,total nitrogen in Jiajia and Shaojia,and the total nitrogen discharge from the Chao River.The results show that:1)The concentration of inorganic nitrogen in the seawater fluctuated significantly throughout the year.The highest levels were observed from July to September,and the water quality did not meet the standards for excellent seawater.Nitrate nitrogen was identified as the primary influencer of the inorganic nitrogen concentration,with nitrate nitrogen accounting for 84%,89.7%,and 82%during July,August,and September.2)Jiajia and Shaojia sections of the Chao River had the lowest total nitrogen concentration during the rainy season of the flood season.The correlation coefficient between inorganic nitrogen concentration in coastal waters and total nitrogen in the Jiajia and Shaojia sections of the Chao River showed a negative correlation of-0.797,-0.785.This negative correlation is related to the increase in water volume during the rainy season of the flood season.3)In coastal waters,the concentration variation of inorganic nitrogen is identical to the total nitrogen in the Chao River.The concentration of inorganic nitrogen in seawater is influenced by the total nitrogen content.The high total nitrogen emission of Jiajia is the main reason for the high total nitrogen emission,the total nitrogen emission is controlled by water flow.
