The simulating experiment constructed a series of “wetland buckets containing soil polluted by petroleum and some wetland plants from the Yellow River Delta. Through monitoring the growth of wetland plants (mainly common reed and cattails) and assaying O/G and TPH in soils according to time-lapse, the function of wetland degrading oil pollution was validated. The petroleum pollutants in the surface layer of soil were decreased by eluviations and degradation. For some wetland plants such as reed and cattail,...
