| Abstract: | Various factors affecting non-point source pollution were analyzed based on pollution generation process and characteristics, including currently pollutant amount, change tendency, environmental self-purification, agricultural activity, climate and hydrological condition, and especially socio-economic activities. Space-time change and area difference for dominant impact factors were also evaluated. The basic pollution investigation and database are thereof proposed for Three Georges Area to provide scientific basis for assessment of agricultural environment quality and overall control measures. |
