| Abstract: | Factors that affect the characteristics of non-point source pollution including natural and social properties were analyzed.According to analysis of mainly reasons that cause non-point source pollution and inter-relationship among different factors,soil quality,vegetation,land use,runoff driving power as well as agroecological pattern were key pollution affecting factors.Based on abundance experimentation and researches,the effect on non-point source pollution and its characteristics were discussed,with res... |
