河岸缓冲带对氮磷污染消减机理及其影响因素研究进展

The review on removal mechanism of nitrogen and phosphorus pollutant and its influencing factors of riparian buffer strips

河岸缓冲带作为河岸生态系统的重要组成部分,是控制水土流失和面源污染、改善水环境的关键措施,对河岸生态系统的生态及水文过程具有重要的影响。概述了国内外关于河岸缓冲带研究的现状,总结了河岸植被缓冲带的主要功能、影响其功能发挥的主要因素和作用机理,并对河岸缓冲带氮磷截留转化作用、机理和影响因素进行阐述,提出了河岸缓冲带研究的发展趋势和重要方向,为今后河岸缓冲带的研究提供参考和借鉴,具有一定的理论价值和实际意义。

The riparian buffer strips, which are considered as a crucial part of riparian ecosystem, play key roles in controlling soil erosion and non-point source pollution, and improving water environment. And the riparian buffer strips also have an important influence on the ecological and hydrological processes of riparian ecosystem. In this paper, latest progress and research status of riparian buffer strips is summarized. And the main functions of riparian vegetation buffer strips, major ingredients and mechanisms influencing its function are also summarized. In addition, the effect of riparian buffer strips on nitrogen and phosphorus transformation, its mechanisms and influencing factors are also discussed. The trend of development and important direction of the research on riparian buffer strips have been put forward,which provides information available for consultation for investigating riparian buffer strips, which has certain theoretical value and practical significance.
