摘　　要：将GIS技术应用到南流江水环境综合整治规划中,对南流江各乡镇水体水土污染整体特征和各污染来源的空间特征进行了空间分析。结果表明,南流江流域水体中化学需氧量、氨氮、总氮、总磷在空间上呈现明显的正相关关系,并且呈现一定的聚集现象;此外,城镇生活污染源、农村生活污染源、工业污染源、禽畜养殖污染源、种植污染源和水产养殖污染源也呈高度空间聚集特征。此结果,为南流江流域水环境综合整治提供了工作靶区。The GIS technology was applied to the comprehensive improvement planning of the Nanliu River water environment,and the spatial characteristics of the water and soil pollution and the spatial characteristics of each pollution source in the water bodies of the Nanliu River were analyzed.The results show that chemical oxygen demand,ammonia nitrogen,total nitrogen and total phosphorus in the Nanliu River basin are positively correlated in space,and show a certain aggregation phenomenon.In addition,urban,rural,industrial pollution sources,poultry and livestock farming,planting and aquaculture pollution sources are of also highly spatial agglomeration.The results provide a target area for comprehensive improvement of water environment in the Nanliu River basin.
