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.
