Seasonal variation of the distributions of microorganism in the root-zones of wetland plants (Phragmites australis, Zizania latifolia, Zizania latifolia etc.), the substrate layers of control SSPs, together with the effects of wastewater treatment were studied. The results are as follows: the numbers of microorganisms in the different plant root-zones were different; the purification effects were also different. The number of microorganisms in the substrate of the control plot becomes smaller with increasing depth. The numbers of bacteria in fall were higher than those in the summer for the three plant zones and the control, and the number of fungi and actinomyces in summer was much higher than that in the fall for control. As for fungi and actinomyces in the experimental systems, most of their difference between the summer and fall were not as big as that in the control.

通过对不同季节芦苇、茭白和香蒲等湿地系统植物根区、无植物对照基质微生物分布状况以及净化效果的研究，结果显示：（1）种植不同植物的湿地系统根区微生物数量不同，其湿地净化效果也不同；（2）对照系统微生物的数量随基质深度的增加而递减；（3）季节变化显示湿地系统秋季的细菌总数量比夏季高；但对照系统夏季的真菌和放线菌数量明显高于秋季；（4）湿地系统TP的去除率夏季高于秋季。
