中文摘要：

为解决流域农业面源污染严重、分布广泛、难以有效治理的问题，在根据流域面源污染“产、流、汇”的扩散特征基础上，创新性地提出“三段式”流域面源污染综合防治方法，即：以源头减量为目的的农业清洁生产，以过程削减为目的的缓冲带截留技术，以终端净化为目的的复合生物强化修复技术，从而形成全流域综合防治体系。在此过程中，应充分重视菌根共生体在生态系统受损和污染环境生态修复领域的优势，对其在流域农业面源污染治理的各个阶段中可能发挥的重要作用进行了介绍与展望，提出一种依托生态系统自净功能并辅助以生物强化手段的面源污染防治理念，是一种绿色、安全、有效、契合农业面源污染扩散特征的全流域综合治理方法，以期为流域水环境质量改善和面源污染治理提供新思路。

英文摘要：

To address severity, wide distribution and difficult control of agricultural non-point source water pollution, a three-stage comprehensive control method was proposed based on its diffusion characteristics. This method consists of agricultural cleaner production for source reduction, buffer strip retention for process reduction and composite bioaugmentation remediation for end purification, which combines a comprehensive control system. Particular attention should be paid to the advantages of mycor- rhizal fungi in restoration of a degraded ecosystem and a polluted environment. The fundamental role of mycorrhizal technology in various stages of agricultural non-point source water pollution control was intro- duced. A concept for non-point source pollution control, which depends on self-purification of a water e- cosystem and assists with bioaugmentation was whole river basin, that is green, safe, effective non-point source water pollution. proposed to create a comprehensive control method for a and agrees with the diffusion characteristics of agricultural
