The growth of reeds was impeded remarkably under a salinity of 15.0±3.4 g CI·L-1 in the first year of this experiment, recovered in the second year and then increased year-by-year afterward. The growth of reeds under a salinity of 9.3±1.9 g CI·Ll was much better than those under 15.0 ± 3.4 g CI·L1. The stress effect was significant for shoot extension but not for the quantity of shoots increase. The dense vegetation bed during the vegetation period （June-October） provided a high rate of evapotranspiration and water loss from HFs （horizontal subsurface flow constructed wetlands）, which made large contributions to reducing pollutant load. The HFs with die-back reeds in the non-vegetation periods （November-March） provided slight evapotranspiration and water loss and made less of a contribution to reducing pollutants removal compared to HFs with the dense vegetation bed in the vegetation periods. However, the HFs with die-back reeds in the non-vegetation periods had higher removal performance than the HF without reeds. This indicated that the rhizosphere of HFs with reeds might play important roles, such as that the microbes around rhizomes might have a higher amount of pollutant-removing microbe activity than those in the HF without reeds during the non-vegetation period.
