Abstract: From the point of view of soil nutrient absorption capacity and crop demand for nutrients,evaluation of livestock manure assimilating capacity of the farmland soil-crop system was conducted with the aid of the spatial analysis and geostatistics techniques on a field basis in Daxing District of Beijing.Results show that the capacity of the farmland soil-crop system is not high on the whole in Daxing District,with 81.65% of the farmland being medium or low capacity,which,apart from the low nutrient holding capacity of the soil was,is related to the planting structure and planting area of Daxing District,especially the lower proportion of farmland and facility agricultural land high in soil fertility.
