摘要:
为了明确琼江流域（安居段）的水质情况，准确评估该流域的主要污染源、主要污染物、重点治理乡镇等，为当地水环境污染控制及治理提供理论依据。采用改进的内梅罗指数法对研究区水质进行了评价，并且将输出系数法和源强系数法相结合，从安居区21个乡镇、5种污染源、3种污染物角度分析了其面源污染情况。结果表明：整个研究区水质较差，水体丰水期的水质劣于枯水期；流域面源污染严重，主要污染源为城镇居民区污水、农田地表径流及畜禽养殖场；污染物主要为氨氮（NH3-N），其次为总磷（TP）；安居镇、拦江镇和西梅镇则是对研究区污染贡献较大的乡镇。研究区面源污染在空间分布上具有较大差异，应根据其分布情况和特征，采取相应措施控制及治理水质污染。
Abstract:
In order to clarify the water quality of Anju Section of the Qiongjiang River Basin, the main pollution sources, major pollutants and key townships in the basin were accurately assessed to provide the theoretical basis for local water pollution control and treatment. The improved Nemero index method was used to evaluate the water quality of the study area, the export coefficient method and source strength coefficient method were combined to analyze the non-point source pollution from 21 townships, 5 pollution sources and 3 pollutants in Anju District. The results showed that the water quality of the whole study area was poor, and the water quality during the flooding season was inferior to that in the dry season; the non-point source pollution of the basin was serious, and the main pollution sources were sewage of urban residential areas, farmland surface runoff and livestock and poultry farms; the main pollutant was ammonia nitrogen (NH3-N), total phosphorus (TP) came to the next; Anju Town, Lanjiang Town and Ximei Town contributed greatly to the pollution of the study area. In general, the non-point source pollution in the study area was greatly different in spatial distribution. It is suggested that the corresponding measures should be taken according to non-point source pollution distribution and its characteristics in the process of control and governance.
