【摘要】 为探讨不同水质评价方法在河流水环境管理中的适用性，本文以西沙河5个采样点2024年监测数据为基础，采用单因子指数法、综合水质标识指数法与改进的内梅罗污染指数法三种方法对水质状况进行了评价与对比。结果显示：3种方法均可有效反映水质情况，但在敏感性、评价精度及应用便利性方面各具特点，实际应用中可采用单因子法为基础，辅以综合指数法或改进的内梅罗污染指数法，提升管理科学性。更多还原

【Abstract】 In order to explore the applicability of different water quality evaluation methods in the management of river water environment, based on the monitoring data of five sampling points of Xisha River in 2024, the water quality conditions using three methods including the single-factor index method, comprehensive water quality labelling index method and improved Nemero pollution index method were evaluated and compared in this paper. The results showed that the three methods can effectively reflect the water quality situation, but each method has its own characteristics in terms of sensitivity, evaluation accuracy and convenience of application. In practical application, the single-factor method can be used as the basis, supplemented by the comprehensive index method or the improved Nemero pollution index method, so as to enhance the scientific management.更多还原
