| 摘 要： | 为了了解长期灌溉猪场废水对农田土壤pH值和土壤养分的影响,采集了河北省京安猪场区域农田清灌区和灌溉8年猪场废水污灌区的耕层(0~20 cm)共52个土壤样品,测定了样品的pH值和土壤养分,应用GIS结合地统计学方法对pH值和养分进行空间结构和分布特征分析。结果表明,研究区pH值和养分的空间分布主要与污灌的猪场废水量和水质有关,与微域地形、土壤质地和种植制度关系不大。 |

| Abstract: | The content of soil nutrients and pH of the 52 soil samples in the plough layer(0~20 cm) of groundwater-irrigated farmland soils and sewage-irrigated farmland soils which had been irrigated swine wastewater of Jing'an swine-farm 8 years was measured,whose aim was to study that soil nutrients and pH in soils were affected by long-term swine wastewater applied.The spatial variability of soil nutrients and pH was studied using GIS(Geographic Information System) technique and geostatistical analysis.The results... |
