| 为解析辽宁海水养殖池塘尾水污染物超标排放风险，本研究通过选取海水养殖池塘养殖规模、养殖产量、环境管控、投饵比、水体污染物超标风险及排水频次为特征评价指标，构建了海水养殖池塘尾水超标排放风险评价体系，并对辽宁省14个沿海县市区的养殖池塘尾水超标排放风险进行了评估。结果表明：海水养殖池塘水体中单一污染因子的超标排放风险指数从高到低依次为pH值、悬浮物、化学需氧量、总磷和总氮。在季节性比较中，秋季的养殖尾水超标排放风险显著高于春季。风险指数的极值范围介于1.54~2.73之间，平均值为2.05。具体到地区，东港市、庄河市、瓦房店市、普兰店区和大洼区的海水养殖池塘尾水超标排放风险较高；旅顺口区、盖州市、老边区和凌海市排放风险处于中等水平；而甘井子区、金州区、西市区、兴城市和绥中县排放风险相对较低。本研究采用层次分析法融合内梅罗综合污染指数法，有效评估和区划了辽宁省沿海县市区海水养殖尾水超标排放的环境风险，为海水养殖池塘尾水超标风险的预警与管控提供了科学依据。 |
| 英文摘要: |
| To analyze the risk of excessive pollutant discharge from seawater aquaculture ponds in Liaoning, this study selected key indicators such as pond size, production volume, environmental management, feed ratio, water pollutant risk, and drainage frequency to construct a risk assessment system for excessive discharge from these ponds. The study evaluated the risk of excessive discharge from 14 coastal counties, cities and districts in Liaoning Province. The results indicate that the risk index for excessive discharge of a single pollutant in seawater aquaculture ponds, from highest to lowest, is pH value, suspended solids, chemical oxygen demand, total phosphorus, and total nitrogen. Seasonal comparisons show that the risk of excessive discharge from aquaculture ponds is significantly higher in autumn than in spring. The risk index ranges from 1.54 to 2.73, with an average of 2.05. Specifically, Donggang City, Zhuanghe City, Wafangdian City, Pulandian District, and Dawa District have higher risks of excessive discharge from seawater aquaculture ponds; Lüshunkou District, Gaizhou City, Laobian District, and Linghai City have moderate risks; while Ganjingzi District, Jinzhou District, Xishi District, Xingcheng City, and Suizhong County have relatively lower risks. This study used a hierarchical analysis method combined with the Nemerow comprehensive pollution index to effectively assess and delineate the environmental risks of excessive discharge from seawater aquaculture ponds in coastal counties,cities and districts of Liaoning Province, providing a scientific basis for early warning and control of excessive discharge risks. |
