摘要
土壤风险是工农业快速发展下资源和环境等问题的集中体现之一。通过分析和评价化肥、农药、畜禽废弃物、污灌和其他因素(污泥、大气沉降、高速公路、工业三废等)在农业生产中的双面性,尤其是负面效应,以警醒生产经营者在农业生产中经济效益和生态效益同等重要。
Due to rapid industrial and agriculture development,soil risk was one of the concentrated ex-pression of problems caused by resources and environment. The two-sided of mineral fertilizers, pesti-cides,animal wastes,sewage irrigation and other factors （sewage sludge,air settlement,expressway,in-dustry three wastes,etc.） was analyzed and evaluated,especially negative effects,which alerted producers that economic benefits and ecological benefits were equally important in the agricultural production.
