平潭海峡公铁两用大桥周边海域海洋生态环境质量与群落结构

Marine ecological environment quality and community structure in the waters surrounding the Pingtan Strait Rail-Cum-Road Bridge

为维护福州至平潭铁路平潭海峡公铁两用大桥周边海域生态系统的完整性和健康性,本文开展了周边海域海洋环境的跟踪监测和质量评价工作。结果表明:在监测期内,监测海域大部分站位的海水水质符合第二类海水水质标准;具有丰富的浮游植物和浮游动物,生境质量良好。大桥施工期和完工后未对监测海域海水水质和生物多样性产生明显影响。

In order to maintain the integrity and health of the ecosystem in the surrounding seas of the Pingtan Strait Rail-Cum-Road Bridge from Fuzhou to Pingtan,this paper conducted follow-up monitoring and quality evaluation of the marine environment.The results show that during the monitoring period,the seawater quality at most stations in the monitoring area met the second-class seawater quality standards,with abundant plankton and good habitat quality.The construction period and completion of the bridge did not significantly affect the seawater quality and biodiversity in the monitoring area.
