摘要: 从土壤对养分消纳能力和作物养分需求角度出发,利用空间分析和地统计学方法,以北京市大兴区为例,进行了以地块为单元的农用地土壤-作物系统对畜禽粪便养分消纳能力评价。结果表明,大兴区农用地土壤-作物系统对畜禽粪便养分消纳能力整体一般,81.65%的农用地处于中下水平。除了因为大兴区的土壤保肥吸收能力整体不强外,还与大兴区的种植结构与种植面积有关,特别是高肥力的耕地与设施农业用地占地比例较小。

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.
