摘要
对赤水河中段十个断面的水质进行分析和评价。结果显示赤水河中段水质整体较好。各指标间相关性分析表明,赤水河中段水体中的污染源主要来源于支流固定的一个或几个,而污染源得到有效地控制后赤水河的水质持续稳定地保持在优良水平。各指标随水期的变化波动幅度较大,今后应继续加强枯水期水质的监控和管理,保证水质继续持续稳定处于优良水平。
The results showed that the overall water quality was very well in the middle of the Chishui river by analyzing and evaluating water quality of ten sections of the river.The correlation among the indicators showed that the main pollution sources were mainly from a fixed one or a few in Chishui River basin.After the effective control of pollution,the water quality continued remaining stable at a level of excellence.Each indicator fluctuated greatly with the water season.It should be continued to strengthen water quality monitoring and management of the dry season to ensure that the water quality kept at a steady level of excellence.
