| 农村面源污染问题日益突出，是当前水污染控制与水环境改善的重点和难点。“十一五”期间，在国家水专项的支持下，以农村面源污染治理的“4R”理论（源头减量—过程阻断—养分再利用—生态修复）为指导，选择江苏省无锡市的直湖港小流域龙延村为综合示范区进行了技术的集成与工程化应用，取得了良好效果。本文以此为典型案例，详细介绍了综合示范区的污染现状、“4R”技术的集成应用与衔接配套、各项技术应用的污染控制效果以及区域环境改善效果，并对“4R”理论的核心内涵以及未来的发展进行了总结和讨论。 |

| Non-point source pollution was more and more serious and became the key factor of the water pollution control in countryside in China. During the eleventh five-year period, under the support of the major S&T program for water pollution control and treatment, Reduce-Retain-Reuse-Restore theory（4R theory） and technologies for controlling agricultural non-point source pollution were applied at Longyan Village, watersheds of Zhihugang river, Tai Lake region. The comprehensive demonstration project for controlling the non-point source pollution was established and showed a good result. In this paper, the status of integrated pollution demonstration area was introduced, the designment of 4R technology and the link between different demonstration projects was also detailed based on the local terrain and river features. Then, the result for applied 4R technology and the improvement effect for local water quality was evaluated. Furthermore, the core of "4R" theory and technology was summarized and its development and application in the future was discussed. |
