2021—2023年郴州市地表水水质状况分析

Analysis of Surface Water Quality in Chenzhou City from 2021 to 2023

为了解郴州市地表水的水质状况,分析郴州市在2021—2023年的水质监测数据,全面评估郴州市的水质变化趋势、空间分布特征及潜在的环境健康风险。结果显示,2021—2023年,郴州市地表水质量显著改善,优良水质(Ⅰ~Ⅲ类)比例逐年上升至100%,且在2022年消除了Ⅳ类及以下水质断面,其中Ⅰ、Ⅱ类水质占比显著提升。通过对比分析各县(市、区)的水质指数,发现地表水水质整体向好,但局部区域,如临武县和北湖区,仍面临水质波动较大的问题。相关研究结论揭示了郴州市水质改善措施的有效性与地域差异性,为制定水资源保护策略提供了科学依据。

To understand the water quality status of surface water in Chenzhou city,analyze the water quality monitoring data of chenzhou city from 2021 to 2023,comprehensively evaluate the water quality change trend,spatial distribution characteristics,and potential environmental health risks in Chenzhou city.The results show that from 2021 to 2023,the surface water quality in Chenzhou city has significantly improved,with the proportion of excellent water quality (Class Ⅰ-Ⅲ) increasing to 100% year by year.In 2022,Class Ⅳ and below water quality sections were eliminated,with a significant increase in the proportion of Class Ⅰ and Ⅱ water quality.By comparing and analyzing the water quality indices of various counties (cities,districts),it was found that the overall surface water quality is improving,but some areas,such as Linwu county and Beihu district,still face significant fluctuations in water quality.The relevant research conclusions reveal the effectiveness and regional differences of water quality improvement measures in Chenzhou city,providing a scientific basis for formulating water resource protection strategies.
