This paper studied the removal effects of three groups of experimental devices made of red soil,yellow-brown soil,and black soil on COD(Chemical oxygen demand),NH4+-N(Total nitrogen),PO43--P(Total phosphorus),and SS(Total suspended solids).The experimental results showed that the treatment effect of red soil on COD and NH4+-N was slightly better than the other two types of soil.However,there was no significant difference among the three soils in the removal of PO43--P.The removal effect of yellow-brown soil on SS was slightly higher,reaching 88.79％.Therefore,it can be concluded that the influencing factors deter-mining the soil type of the concave green space are not solely dependent on the soil's own pollution inter-ception degree,but also on the convenience of soil acquisition during engineering construction and the suit-ability of the soil for the growth of green space plants.
