The paper discussed agricultural materials application, discharge status of animal manures, and their hazards to soil. Four indicator as input density of fertilizer, pesticide, plastic, and density of animal manures discharge were calculated using cluster analysis in 31 areas in China. Results showed that the contamination of agricultural soil had significant regional differentiation characteristics, which aggregated into 3 types, 11 areas were in 1st type, 9 in 2nd, and 11 in 3rd type, and related strategies were proposed in this paper according to different regional differentiation characteristics.
