2017-2024年小塔山水库水质变化特征及富营养化研究OA
Water quality variation characteristics and eutrophication of Xiaotashan Reservoir from 2017 to 2024
小塔山水库是连云港市一座兼具多种功能的大型人工水库,对维护城市水资源安全和供水稳定起到重要支撑作用.采用单因子评价法和营养状态指数法对小塔山水库2017-2024年水质和水体富营养化程度进行分析,利用SPSS Pro对水库营养状态指数影响因子进行了Pearson相关性分析.结果表明,小塔山水库近年来各项水质指标呈现不同表现结果,水质状况总体优良,对比2020-2022年间水质,2024年出现明显好转,水温和氮、磷等营养盐元素被认为是水库富营养化的重要影响因子.
Xiaotashan Reservoir is a large artificial reservoir in Lianyungang City with multiple functions,playing a crucial role in maintaining urban water resource security and stabilizing water supply.Water quality and eutrophication level of Xiaotashan Reservoir from 2017 to 2024 were evaluated using the single-factor evaluation method and the Trophic State Index(TSI)method.Pearson correlation analysis of the factors influencing the trophic state index was carried out using SPSS Pro.The results show that water quality indicators in Xiaotashan Reservoir exhibited different trends in recent years.The overall water quality was generally good,and a significant improvement was observed in 2024 compared with the period 2020-2022.Water temperature and nutrient salts such as nitrogen and phosphorus were identified as key factors affecting reservoir eutrophication.
