摘　　要：收集了乐清湾多年的水质监测资料,分析了乐清湾各水质指标在时间和空间上的变化规律。在此基础上,分别从乐清湾外部污染源变化,海岸工程引起的水动力变化和水产养殖业产生的内部污染源的变化等几方面,对乐清湾水质变化的原因进行了探讨。Monitoring data of water-quality in Yueqing Bay in the past years are collected, and the change trend of the water-quality indexes in Yueqing Bay thus is drawn from the space and time dimensions. The cause resulted to the change of water-quality is then probed in terms of external contamination sources, the hydrodynamic change induced by the near ocean engineering projects, as well as internal contamination sources from local agricultural activities.
