By studying bioretention system，it was found that the system's hydrological effect was mainly concerned with soil
structure，the depth of design system，filling ratio，permeability，the ratio of facilities surface area to drainage area，climate
and other relevant factors． Its nitrogen and phosphorus removal effience was relevent to the properties of the fillers，the
saturated zone control，hydraulic retention time and other factors． The removal rate of TSS was usually up to 60%，fecal
coliform，escherichia coli removal rate could reach about 70%． Metal ion removal and vegetation types were closely related．
