Abstract：Yellow-brown soil was selected to artificially prepare petroleum hydrocarbon contaminated soil in this paper,and the effect of addition ratio of greenery waste and incubation time on TPH degradation were studied in the condition of planting bermuda grass,ryegrass and tall fescue by pot experiment in the laboratory.The results showed that the combination of both planting grass and adding greenery waste measures were more conducive to remediate TPH contaminated soils.And the effect of different grass on TPH degradation followed the order as tall fescue ＞ ryegrass ＞ bermuda grass,and the remediation of TPH reached the best effect when addition ratio of greenery waste was 10％.TPH degradation bacterium increased the maximum and then decreased with the increasing of incubation time,moreover,the trends were not influenced by the addition ratio of greenery waste.And the numbers of TPH degradation bacterium and grass biomass were the main factors influencing the remediation effect of TPH contaminated soils.
