【摘要】Lots of exogenous feed and fish excreta make the nutrient, phosphate and organic increase, cause water quality deterioration. This is a main restricted factor to the development of marine aquaculture. Group A and group B floating marine aquaculture systems were constructed which area ratio of plants was 3： 2. The study was conducted to examine the N, P removal ability of Sesuvium portulacastrum.
After
two
months
of
treatment,
Sesuvium
portulacastrum grew well at salinity 15, group A and B showed efficient N, P removal ability, but there was no significant difference （ P 〉 0.05 ） between them. When the plants grew stable, the results showed that group A and B had excellent removals, with efficiencies 74 % - 91% and 60% - 91% for ammonia nitrogen, 93 % - 98 % and 71% - 97% for nitrite nitrogen, 11%-25% and 14%-33% for total nitrogen, 67%-85% and 61% -81% for COD and 41% -68% and 35% -71% for total phosphorus. The group A and B have significant difference （P 〈0.05） with control group for the concentration of ammonia nitrogen, nitrite nitrogen, COD and total phosphorus. The total nitrogen removal couldn＇t examined yet, but the ammonia nitrogen and nitrite nitrogen removal reacted
