摘　　要：为在寒冷地区建立高效的滨岸缓冲带水体工程,选择早熟禾、高羊茅、3种本地耐寒性植物,研究剪股颖构建河流滨岸缓冲带植物的经济性、生长特性、光合作用及其对悬浮物、氮、磷的净化能力。结果表明,3种植物在经济性方面高羊茅与早熟禾差别不大,远低于剪股颖;在生长特性方面,早熟禾与高羊茅的表现相近,高羊茅略好,但比剪股颖表现优秀,早熟禾在净光合作用速率、蒸腾速率以及水分利用效率方面比高羊茅及剪股颖出色;在面源污染物去除率方面,地表径流悬浮物的去除中,早熟禾表现突出;在溶解性磷与总氮的净化中,3种植物表现差异不大,早熟禾略有优势。综合比较各项指标,早熟禾可作为寒冷地区构建滨岸缓冲带较为理想的备选植物。In order to establish an efficient riparian buffer zone in cold regions, 3 local cold resistant plant species, namely, Poa pratensis L, Festuca arundinacea and Agrostis stolonifera, are selected for study of the costs, growth characteristics, photosynthesis ability and purification ability for suspended solid particles, total nitrogen（TN） and soluble phosphorus of the plants used for construction of riparian buffer zone. The results show that the cost of Festuca arundinacea and Poa pratensis L is far lower than that of Agrostis stolonifera. The growth rate of Festuca arundinacea and Poa pratensis L is better than that of Agrostis stolonifera, and Festuca arundinacea is slightly better than Poa pratensis L. Moreover, Poa pratensis L performs better than Festuca arundinacea and Agrostis stolonifera from the aspects of net photosynthetic rate, transpiration rate and water use efficiency. With regard to none-point source pollutant removal, Poa pratensis L does well in suspended solids removal. There is no much difference between the three plants in removal of TN and soluble phosphorus, but Poa pratensis L has slight advantages. Comprehensive comparison of various indicators among these plants shows that Poa pratensis L is more ideal alternative plant for riparian buffer zone in cold regions.
