【摘要】 详细阐述了我国在不同流域尺度下农田氮、磷径流流失的主要监测方法，包括人工模拟试验法、野外实地监测法（径流小区监测法、小流域定点监测法、平方公里网格监测法）和建立模型法（经验模型、物理机理模型、水文过程模型、生态系统模型），综述了在农田氮、磷径流流失风险评估方法（野外实测法、输出系数模型法、物理模型法、污染指数法）方面的研究进展，并对该领域的未来研究方向进行了展望。更多还原

【Abstract】 In the paper, the monitoring methods of farmland nitrogen and phosphorus runoff loss at different scales and the commonly used risk assessment methods for nitrogen and phosphorus runoff loss was expounded, including the artificial simulation test, field monitoring method(runoff cell monitoring method, small watershed fixed point monitoring method and square kilometer grid monitoring method) and modeling method(empirical model, physical mechanism model, hydrological process model and ecological system model). The research progress of nitrogen and phosphorus runoff risk assessment methods(field measurement method, output coefficient model method, physical model method and pollution index method) was reviewed,and the future research direction was prospected.更多还原
