Abstract. The evaluation of comprehensive impacts on rural areas with spatial relationships are necessary to implement rural pollution control with scientific plan, to protect the surface and ground water, to assign water carrying capacity in urban. In general, rural areas are geographic regions located outside the cities and towns. These areas actually conceal serious environmental problems, such as: non-point pollution from agriculture, poultry and livestock pollution from farming, domestic pollution from villages and community, etc. In spite of the environment criterions existed in single industry (agriculture or farming), it is solved as individual event without integrated assessment of full affects and scientific environment planning for a specific rural areas. However, rural areas have common characteristic in spatial distribution. Geographical Information System (GIS) based analysis is the process of deriving information from one or more layers of spatial data. A new accurate GIS-based analysis method is applied in rural Sichuan Province, China as a case study in this paper to identify various pollution sources avoiding the interference of the administrative units and the locations intersected where another new transformation of nutrients exists. It reveals new or previously unidentified relationships within and between datasets, increasing our understanding of the rural place and acquirement optimal decisions through the process of geovisualization.
