%X The organic chlorine pesticide contaminated soil has potential risks to ecologic environment. It is necessary to study ecological effects of the protozoa caused by the organic chlorine pesticide. The basic physical and chemical properties of the collected soils from an abandoned pesticide plant were measured. Meanwhile, the residue concentrations of DDTs and HCHs were assessed. The community structure and abundance of the protozoa in the soil samples were analyzed. The experiments revealed that the dominant species of the three groups of the protozoa was flagellate, while ciliate was the rare species. The correlation analysis between the basic physical and chemical properties of the soils and the abundance of soil protozoa indicated that total nitrogen was significantly positive correlated with the abundance of flagellate, ciliate and soil protozoa. Total phosphorus only significantly affected the abundance of sarcodina. The abundance of soil protozoa in the contaminated soil samples was significantly lower than those in the control soils, suggesting that the long-term residue of organic chlorine pesticides in soils decreased the abundance of the soil protozoa.
