| 摘 要： | 河岸缓冲区对氮素的有效截留以阻止其进入河流已得到广泛的认可，是美国资源局所认可的一种最佳管理措施。总结河岸缓冲区中氮素截留的主要机制、影响因素及缓冲区的管理原则。最主要截留机制为反硝化作用与植物吸收，相应的最主要影响因素是缓冲区的水文特征。为达到较好的氮素截留效率，必须重建退化的缓冲区、保护缓冲区的完整性与不受干扰，并与其他流域管理措施相结合。

| Abstract: | Riparian buffers are widely accepted to be an effective means of buffering rivers against nitrogen and thus are considered a best management practice （BMP） by State and Federal resource agencies, U. S. A. This paper reviewed the past researches of nitrogen removal of riparian buffers, summarized the nitrogen removal mechanisms in riparian buffers and also the factors affecting removal efficiency. The most important removal mechanisms are denitrification and plant uptake in soil, which are mainly affected by groundwater flow path. To achieve better removal effectiveness, disturbance to riparian buffers are unallowable and a conjunction with other watershed management countermeasures is needed. |
