摘要：

为了保护怀化市区水体环境质量，为怀化市生态宜居城市建设提供科学依据，对流经怀化市区的舞水河支流太平溪水质分平水期、枯水期2个时期进行了实地调查与监测，并结合太平溪历年的水质状况，对其水质进行了综合评价。结果表明，太平溪各个断面TP和NH3-N含量明显偏高，均超出国家Ⅴ类水质标准，说明太平溪存在明显的生活污水污染；水体中DO含量低，有些断面水质未达到的Ⅳ类水质标准，有些未达到Ⅴ类水质标准；太平溪汇入舞水河后的湾滩断面，其水体中NH3-N、TP含量均要高于汇入舞水河之前的陈家断面，说明太平溪水体污染对舞水河水质产生了一定的影响；结合太平溪历年水质监测数据分析发现，水体中DO的含量持续降低，而TP含量却持续增高，水体污染日益严重。因此，进一步加强太平溪水体的综合治理对舞水河的保护以及怀化市建设生态宜居城市意义重大。

Abstract:

In order to protect the water environmental quality of Huaihua City and provide scientific basis for the construction of ecological livable city of Huaihua, the author made a field investigation and monitoring of water quality of Taiping River of Huaihua City, which was divided into mean and dry water periods. The author also made a comprehensive evaluation of water quality with the monitoring data of the past years of Taiping River. The results showed that the content of TP and NH3-N of each section was high, which all exceeded the state V water quality standard. The content of DO in water was low. Some section did not reach IV water quality standard and some even did not reach V water quality standard. Wantan section had a higher content of TP and NH3-N than Chenjia section, which explained the pollution of Taiping River had a certain effect on the water quality of Wushui River. Combined with the monitoring data of the past years of Taiping River, the author found that the content of DO in water decreased continuously, and the content of TP increased continuously. The water pollution was increasingly serious. Therefore, further management of Taiping River is very important to the protection of Wushui River and the construction of ecological livable city of Huaihua.
