| 摘 要： | 植物浮床已经被越来越多地应用于净化城市景观水体．其净化原理是通过植物根系对污染物的吸附和吸收作用，以收获植物体的形式将其搬离水体，从而达到净化水体的目的．具有良好的景观效果、净化水体成本低及提高水体生物多样性等优点．当前其应用中存在的主要问题是浮床植物种类不够丰富，在冬季水体净化功能低下，应用模式尚有待研究等．

| Abstract: | Plant floating bed has more frequently been used in purifying the waters for urban landscape nowadays. With its particular advantages of landscape effect, low cost and upgrading biodiversity, the plant floating bed can be achieved the purpose for purifying the waters through absorbing the pollutant by root system, which plants are to be collected for clearing the pollutant away from the waters ultimately. At present, there exist main issues in the application of plant floating bed, such as lack of plant species, low purification function in winter and the application mode to be further studied. |
