摘要
为研究动态声呐在核电冷源取水海域水母监测中的应用,2023年7月23日至8月5日,在辽东湾东部核电站冷源取水口监测站位(JFQSK)使用动态声呐对水母生物量进行监测,并同步使用网具法进行比较。研究结果表明:动态声呐法测得的水母生物量与网具法变化趋势一致;声呐法水母生物量可依据声呐视频显示的水母个数、水深、海流流速及水母单体重量四个要素计算得出;在辽东湾东部近岸海域核电冷源保障监测预警中,动态声呐法水母监测黄色风险预警值为350 kg/10^(4)m^(3),红色风险预警值为550 kg/10^(4)m^(3)。
To study the application of dynamic sonar in jellyfish monitoring in the intake areas of nuclear power cooling sources,from July 23 to August 5,2023,the biomass of jellyfish was monitored using dynamic sonar at the monitoring station(JFQSK)at the cooling water intake of the nuclear power plant in the eastern Liaodong Bay.Simultaneously,the netting method was used for comparison.The results showed that the jellyfish biomass measured by the dynamic sonar method was consistent with the trends observed using the netting method.The biomass of jellyfish using the sonar method can be calculated based on four factors:the number of jellyfish shown in the sonar video,water depth,current speed,and the individual weight of jellyfish.According to the research,in the monitoring and early warning system for the protection of nuclear power cooling sources in the eastern coastal waters of Liaodong Bay,the yellow risk warning threshold for jellyfish monitoring using the dynamic sonar method is 350 kg/10^(4)m^(3),and the red risk warning threshold is 550 kg/10^(4)m^(3).
