摘要
海洋工程建设中周边海域生态环境变化是开发建设中的关键技术问题,有利于近岸海洋环境保护及资源开发利用。本研究根据2011—2022年宁波梅山港区码头工程实测的4个航次的水文泥沙、水质、沉积物、生物等资料,分析了该工程施工前(2011)、施工期(2016年、2017年)和施工后(2022年)周边海洋环境的变化特征。研究发现:梅山港区码头工程周边海域水质、沉积物、生物生态的施工前、施工中、施工后变化均在有限范围内波动,说明该工程施工对周边海域水质质量、沉积物质量以及海洋生物生态未造成明显影响。工程施工对周边海洋生态环境造成影响有限,说明该工程建设符合海洋环境保护要求。研究结论作为开展宁波梅山港区码头工程建设的重要依据,同时也为该海域的海洋生态环境保护提供一定的参考依据。
The changes in the ecological environment of the surrounding sea areas during ocean engineering construction are a key technical issue in the development and construction,which is beneficial for the protection of the nearshore marine environment and the development and utilization of resources.This study analyzes the changes in the surrounding marine environment during the pre construction(2011),construction period(2016,2017),and post construction(2022)periods of the project,based on the hydrological,sediment,water quality,sediment,and biological data measured on four voyages of the Ningbo Meishan Port Terminal Project from 2011to 2022.Research has found that the changes in water quality,sediment,and biological ecology in the surrounding waters of the Meishan Port Terminal Project fluctuate within a limited range before,during,and after construction,indicating that the construction of the project hasnot had a significant impact on the water quality,sediment quality,and marine biological ecology in the surrounding waters.The construction of the project did not have a limited impact on the surrounding marine ecological environment,indicating that the construction of the project meets the requirements for marine environmental protection.The research conclusion serves as an important basis for the construction of the Ningbo Meishan Port Terminal Project,and also provides a certain reference basis for the protection of the marine ecological environment in the sea area.
