| 英文摘要 | 具有一定群落结构的河岸植被土壤系统内部具有较大的生物生存空间和相互作用区域,其间生物地球化学联合机制,可以减缓径流,捕获泥沙,截断或去除地表径流、壤中流或渗漏水及浅层地下水中的氮磷等元素。各种污染物的净化效果受系统内部和外部条件影响,主要包括:污染负荷、系统宽度、植被类型、水文地质、土壤条件等因素。; Riparian ecosystem as the most important buffer area between terrestrial and aquatic ecosystems has been proposed as an effective means for combating agricultural diffuse source nutrient transport to streams and lakes.Riparian zones can disperse and reduce the velocity of surface runoff and promote infiltration,sediment deposition and nutrient retention as well as lower nutrient concentrations in shallow groundwater.There are many factors regulating nutrient removal rates in riparian zones,such as width and slope gradient of buffer zones,nutrient loading,vegetation types,hydrogeology,mechanism,temporal and spatial variation.Therefore,the use of riparian management zones is well established worldwide as a best management practice for water quality improvement in agricultural watersheds.; 国家自然科学基金资助项目(40671116);福建省自然科学基金重点项目(D0720002);教育部新世纪优秀人才支持计划;福建省高校新世纪优秀人才支持计划 |
