摘　　要：在模拟潮汐条件下以正常、5倍和10倍浓度的人工污水处理红树林植物白骨壤1a生幼苗,测定植株的根长、根径、茎高、茎径、叶片数、生物量以及开花结果等指标。结果表明:正常浓度和5倍浓度组的上述指标显著高于对照组,10倍浓度组的这些指标大于或接近对照组;说明:一定浓度的污水可以促进白骨壤的生长和开花结果。The one year old seedlings of Avicennia marina were treated with synthetic wastewater for a year under simulated tidal condition, namely NW, FW and TW three different concentrations. NW had the characteristics similar to conventional municipal wastewater, while FW and TW contained five and ten times of the nutrients and heavy metals found in municipal wastewater respectively, 1.5%salinity of artificial seawater as control. The indexes of root length, root diameter, stem height, stem diameter, leaves quantities, biomass, flowering and fruiting of Avicennia marina plants were examined. The results showed that: Treating of synthetic wastewater could stimulate growth of Avicennia marina plants . Those indexes of NW and FW were obviously higher than that of control, and the most indexes of TW were higher or similar to that of control. 
