摘　　要：为提高水质评价精度和准确性,以湖南张家界大鲵国家级自然保护区2018—2022年水质监测数据为基础,采用单因子指数法、综合水质指数法、灰色关联分析法、秩相关系数4种评价方法,对保护区水质及动态变化进行分析评价。评价结果显示,保护区水质除TN外,其余各项指标均达到地表水Ⅰ类或Ⅱ类标准,采用综合水质指数法或灰色关联分析法分析结果优于单因子指数评价结果;从空间上分析,大鲵出苗点水质优于河道水质,采用秩相关系数法对2018—2022年水质变化趋势分析表明,监测时段内保护区水质基本呈稳定状态,部分出苗点及河道水质呈向好趋势。鉴于保护区管理工作需要,建议采用单因子指数法识别水质超标因子,可为后续水生态、水环境管理提供支撑;借助综合水质指数法及灰色关联分析法,利于全面评价保护区水质总体达标情况。研究成果为自然保护区开展水质评价与水环境保护提供方法支撑。Based on the water quality monitoring data of Zhangjiajie Giant Salamander National Nature Reserve during 2018—2022,four evaluation methods,including single factor index method,comprehensive water quality index method,grey correlation analysis method and rank correlation coefficient,were used to analyze and evaluate the water quality and its dynamic changes in the reserve.The evaluation results showed that all the water quality indexes except TN reached the ClassⅠor ClassⅡstandard of surface water,and the results of comprehensive water quality index method or grey correlation analysis method were better than the single factor index evaluation results.From the spatial analysis,the water quality of emerging seedling points was superior to that of river courses.The analysis of water quality trend during 2018—2022 by using the rank correlation coefficient method showed that the water quality of protected areas was basically stable during the monitoring period,and the water quality of some emerging seedling points and river courses showed a good trend.In consideration of conservation area management,the single factor index method can master the pollution factor,and provide support for the subsequent water ecology and water environment management.The comprehensive water quality index method and grey correlation analysis method can comprehensively evaluate the overall water quality standards of the protected areas.The research results provide method support for water quality assessment and water environment protection in nature reserves.
