摘要: [目的] 在前人研究的基础上,对长江流域等热点研究区域的污染物输出系数值进行总结,估算出濑溪河流域泸县段的TN、TP的污染负荷。[方法] 利用输出系数模型的方法。[结果] 结果表明,濑溪河泸县段非点源TN负荷量为3701.54t/a、TP负荷量为688.72t/a,其中农田径流污染、农村生活污染及畜禽养殖污染对非点源TN、TP的贡献率较大,农田径流污染为TN的主要来源,畜禽养殖污染为TP的主要来源,且TN负荷量远大于TP负荷量。[结论] 非点源污染是影响濑溪河泸县段水环境质量的一个重要方面,应该引起足够重视,并采取相应措施。

Abstract: [Objective] The objective of this study was to calculate the load of the non-point source total nitrogen (TN) and total phosphorus (TP) in Laixi river basin (Luxian section).[Method] Output coefficient model was used to calculate the TN and TP load.[Results] The load of TN and TP from non-point pollution source equal 3 701.54 t/a and 688.72 t/a,respectively.Agricultural fertilizer pollution,the rural domestic pollution and livestock pollution make a main proportion.Agricultural fertilizer pollution and livestock pollution are the main sources for TN and TP,respectively.TN load is much more than the TP load.[Conclusion] Non-point source pollution is an important aspect for the water quality in Laixi river basin (Luxian section) Therefore,it should be pay sufficient attention and take appropriate measures.

Key words: output coefficient model, non-point source pollution, TN Load, TP Load, Laixi river basin (Luxian section)
