【摘要】 为了解海上风电磁场对海洋生态及生物资源的影响,以如东龙源风电示范区为例开展了海底磁场的现场探测、模拟磁场对海洋生物的影响试验,以及海洋生态与生物资源的分布规律研究。结果显示总长度31km探测线,除正常地磁场外,频率50Hz电缆在海洋表层产生的工频磁场强度平均为16nT。模拟磁场1.00±0.01 mT下,黑鲷存活及行为在21 d内受磁场影响明显(P <0.05),磁场撤销后14 d内无显著性差异(P> 0.05)。海洋生态及生物资源的分布与距离风电场的远近无相关显著性,可能是磁场随距离衰减极速,对海洋表层、中层的海洋生态和生物资源影响不大。该研究为评价风电磁场对海洋生物的影响奠定了基础。更多还原

【Abstract】 In order to know the effects of the magnetic field of the offshore wind farm on marine ecology and biological resources. A case study was carried out in Rudong Longyuan Wind Power Demonstration Zone. The average intensity of power frequency magnetic field produced by 50 Hz cable in the ocean surface layer was 16 nT except for normal geomagnetic field. The survival and behavior of Sparus macrocephlus were significantly affected by the magnetic field with 1.00+0.01 m T in 21 days, but there was no significant difference within 14 days by the magnetic field canceled. The distribution of marine ecology and biological resources had no significant correlation with the distance. It was possible that the magnetic field decayed rapidly with the distance. It may had a direct and indirect role in promoting the study influence of wind and electromagnetic fields on marine life.更多还原
