| 摘 要： | 以苏州古城区内的河道为研究对象，采用静态培养的方式，研究了上覆水体不同富营养化程度对底泥中P释放/吸附的影响。研究结果表明：截断外源污染后，苏州河道底泥对水体中营养盐P呈现吸收状态；随着上覆水体磷酸盐浓度的增大，单位面积底泥累积吸收的磷酸盐就越多；上覆水与底泥比值越大，底泥对P的吸附率有减小的趋势。

| Abstract: | Studies on the influence of water body eutrophication level on phosphorus releasing/absorption from sediments in Suzhou River were conducted under mimicked static state experiments. The results were given as follows: sediments from Suzhou River can absorb P in static state without external input; with the increasing of phosphate concentration, the phosphate adsorption capacity of sediment also has increased; the higher ratio of over-lying water to sediment it is, the lower phosphorus absorbing capacity on sediments will be. |

| Keywords: | eutrophication sediments phosphorus release absorption |
