| 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 ca... |
