摘要： Farmland pollution load of livestock manure nutrient is an important factor of the environmental pollution, and excessive application of livestock manure will produce a serious impact on the ecology and environment. A new method was proposed to estimate farmland pollution load of livestock manure nutrient and the procedure was shown as follows. Firstly, phosphorus nutrient from livestock manure was estimated in Daxing district. Secondly, the estimation model of farmland pollution load of livestock manure nutrient was proposed. Finally, the farmland pollution load of phosphorus nutrient in field patch scale of Daxing district in Beijing was estimated and compared to the farmland pollution load of phosphorus nutrient by traditional statistical analysis method. The results showed that the method proposed is more reasonable to estimate the farmland pollution load of livestock manure nutrient in field patch scale
