【摘要】 坡耕地极易发生土壤侵蚀,由此带来的水土流失及农业面源污染严重制约了丘陵地区生态环境质量。坡面构建植物篱或过滤带可通过植物、土壤及微生物的共同作用增强土壤入渗、拦截径流和泥沙、过滤氮磷及污染物,是预防坡耕地水土流失、保护生态环境质量的有效手段。本文在整理分析国内外大量文献的基础上,系统总结了不同植物篱和过滤带对径流、泥沙、氮、磷,以及污染物的阻控效果,分析了该技术阻控效果的影响因素,并深刻阐述了植物篱对水土流失的阻控机理,最后分析了目前存在的问题,提出了进一步的研究建议,以期为植物篱或过滤带技术的理论研究及应用提供参考,为丘陵地区耕地可持续利用、生态农业建设提供依据。更多还原

【Abstract】 Soil erosion on sloping land induces soil and water loss and non-point pollution, causing serious adverse effects on ecology and environment quality in hilly areas. Use of plant hedges or filter strips is an effective method to prevent soil and water loss and to protect ecology and environment quality. It can effectively increase soil infiltration and reduce the runoff,sediment, nitrogen(N), phosphorus(P), and pollutants through the combined action of plants, soil, and microorganisms. This manuscript summarizes the effectiveness of different plant hedges and filter strips in reducing the runoff, sediment, N, P, and pollutants, analyzes the associated impact factors, discusses the interrupting mechanisms, and, finally, proposes contents that need further study in the future. It can provide a reference for further research and the application of plant hedges or filter strip technology and provides evidence for sustainable utilization of cultivated land and ecological agriculture construction in hilly areas.更多还原
