近年来,中国沿海水域经常爆发水母,显著影响结构,功能,安全,核电厂冷却水取水口和附近生态系统的经济性。因此,这项研究的重点是中国沿海水域的水母爆发,特别是在山东半岛附近。通过分析水母丰度数据,综合环境因素的广义相加模型表明,温度和盐度对水母密度有很大影响。结果显示水母密度在不同年份之间的变化,沿海地区密度较高。该模型解释了42.2%的方差,突出了温度(20-26°C)和水母密度之间的正相关关系,以及盐度的影响(27.5-29分)。此外,洋流在近岸水母聚集中起着重要作用,洋流和站点坐标之间的相关性。本研究旨在探讨水母水华与环境因子的关系。研究结果为预防和控制核电站冷却系统堵塞提供了数据支持,并为核电厂监测措施的实施提供数据依据。
In recent years, there have been frequent
jellyfish outbreaks in Chinese coastal waters, significantly impacting the structure, functionality, safety, and economy of nuclear power plant cooling water intake and nearby ecosystems. Therefore, this study focuses on
jellyfish outbreaks in Chinese coastal waters, particularly near the Shandong Peninsula. By analyzing
jellyfish abundance data, a Generalized Additive Model integrating environmental factors reveals that temperature and salinity greatly influence
jellyfish density. The results show variations in
jellyfish density among years, with higher densities in coastal areas. The model explains 42.2% of the variance, highlighting the positive correlation between temperature (20-26 °C) and jellyfish density, as well as the impact of salinity (27.5-29‱). Additionally, ocean currents play a significant role in nearshore jellyfish aggregation, with a correlation between ocean currents and site coordinates. This study aims to investigate the relationship between jellyfish blooms and environmental factors. The results obtained from the study provide data support for the prevention and control of blockages in nuclear power plant cooling systems, and provide a data basis for the implementation of monitoring measures in nuclear power plants.
