摘要： The traditional method of applying animal manure nutrient (AMN) to farmland treated the farmland area as a unity usually and allocated animal manure nutrient to farmland equally. In this paper, a spatial allocation model of animal manure nutrient was built based on the parameters which effected the spatial allocation of AMN and realized application taking animal manure potassium nutrient (AMP) in Daxing District of Beijing as an example. Results showed that 5419178.18 kg AMP was allocated to 8481 farmlands and the surplus AMP was 528697.35 kg. The maximum, minimum, and average of AMP in farmland was 3251.28, 0.90 and 638.98 kg respectively and no AMP in farmland exceed the maximum potassium nutrient load of farmland. Comparing to the inverse distance weighting interpolation and the method of simply allocating statistical data, the method proposed in this paper could allocate AMN to farmland in land patch scale scientifically and reasonably.
