	<span style=\"font-size:14px;\">捕鱼作业区域作为近岸海域渔船活动的主要区域，对其进行科学客观的评价十分重要。基于10个采样点2021年10月捕鱼作业期间监测数据，运用改进的灰色关联法评价了近岸捕鱼作业区水质，并结合该区域水质的实际情况，与综合指数评价法的评价结果进行了对比。改进的灰色关联法评价结果表明，研究区主要的污染影响因子为化学需氧量、生化需氧量、无机氮、非离子氨和活性磷酸盐。综合指数评价法和改进的灰色关联法的评价结果在点位优劣上趋势一致，但改进的灰色关联法的评价结果更符合实际。<br />
Fishing operation area is the main
activity area for fishing activities of immediate off shore area. It is very
important to evaluate the water quality scientifically and objectively. Based
on the monitoring data of 14 indicators of 10 sampling points during the
fishing operation period in 2021, improved grey correlation method is used to evaluate
the water quality of fishing operation area. Combined with the actual situation
of fishing activity area, the evaluation results are compared with the
composite index method. The results of improved grey correlation method show
that the comprehensive evaluation results of fishing activities area water
quality in the study area are better. The main pollution impact factors of the
study area include chemical oxygen demand, biochemical oxygen demand, inorganic
nitrogen, nonionic ammonia and phosphate. Comparing with the composite index
method and improved grey correlation method, the advantage and disadvantage
trends of the sampling points are basically consistent. In comparison, the
evaluation results of improved grey correlation method are more in line with the
reality.</span>
