| 中文摘要: |
| 通过地理信息系统（Geographic Information System，GIS）技术对濑溪河流域（泸县境内）进行水系提取及流域划分，并利用GIS空间技术分析了各乡镇污染贡献度。选取城镇居民生活污水、城镇地表径流、畜禽散养、农村生活污水以及化肥流失5大污染源，计算各镇总等标污染负荷比。结果表明，研究区内农村畜禽散养、化肥流失、生活污水的污染源总和比重高达69.71%，福集镇占研究区乡镇总污染的31.17%，导致泸县濑溪河水质差的主要原因是农村非点源污染，并提出了针对性的污染防治对策建议。 |

| In this study, we analyzed the pollution situation of Laixi River basin (territory of Lu County) and the spatial distribution of non-point source pollution along Laixi River. Five main pollution sources (urban domestic sewage, urban surface runoff, rural cage-free livestock, rural domestic sewage and fertilizer runoff) were selected to calculate the total equal standard pollution load ratio. Geographic Information System (GIS) technology was used to extract the watersheds and drainage system of Laixi River and the spatial analysis was utilized to analyze the spatial distribution of total pollution load. The results showed that rural cage-free livestock, rural domestic sewage and fertilizer runoff were the main pollution sources, accounting for 69.71% of the total pollution load, and the contribution of total pollution from Fuji town was quantified as 31.17%. Therefore, the poor water quality of Laixi River was mainly due to the rural non-point source pollution. The corresponding countermeasures are proposed to prevent and control the pollution. |
