| 摘要: |
| 【目的】系统评价盘锦市地表灌溉水的水质状况，为盘锦市灌溉水质安全和农业高质量发展提供数据支撑。【方法】分别于平水期、丰水期和枯水期对盘锦市内6个监测点位进行调查分析，利用综合污染指数（CPI）、内梅罗综合污染指数（P综）、钠量法（SC）和残余碳酸钠法（RSC），对地表灌溉水进行水质评价。【结果】地表灌溉水的水质指标存在明显的时空变异性，主要污染指标为氨态氮、氯化物和粪大肠菌群。基于综合污染指数法的评价结果显示，地表灌溉水的水质总体较好，水质由平水期至枯水期从清洁状态向尚清洁状态发生转变，东风监测点存在季节性污染；基于内梅罗综合污染指数（P综）的评价结果表明，灌溉水水质总体较好，丰水期水质优于平水期和枯水期，田庄台、西绕和双绕监测点位存在季节性污染；灌溉适用性评价结果显示，地表水总体可适用于灌溉，丰水期灌溉适用性优于平水期和枯水期。【结论】盘锦市地表灌溉水水质较好且适用于灌溉。 |

| Abstract: |
| 【Objective】This paper presents the results of a comprehensive and rigorous assessment of the environmental quality of surface irrigation water in Panjin City, aimed to provide essential data to help water ecological protection and developing high-quality agriculture.【Method】Water samples were taken at normal, wet and dry seasons at different locations across the region to analyze their chemical compositions. Water quality was evaluated using the comprehensive pollution index method, Nemerow comprehensive pollution index method, sodium concentration method (SC), and the residual sodium carbonate method (SRC).【Result】Water quality indicators varied spatiotemporally. The ammonia nitrogen, chloride and fecal coliform in the water exceeded the values set in the standard. Results calculated from the comprehensive pollution index method showed that the overall quality of the surface irrigation water was good. From normal to dry seasons, water quality changed from clean to relatively clean. There was a seasonal pollution at the sampling points at Dongfeng. The results calculated from the Nemerow comprehensive pollution index method showed that the water quality was relatively good, and that it was better in the wet season than in the normal and dry seasons. There was a seasonal pollution at the sampling points at Tianzhuangtai, Xirao and Shuangrao. As well as the evaluation results of the SC and RSC, the surface water in Panjin City was generally suitable for irrigation, and the water quality in the wet season was better than that in the normal and dry season.【Conclusion】The overall surface water quality in Panjin City is relatively good and deemed suitable for irrigation. It can sustain potential development of the region for high-quality agriculture. |
