| Abstract: | Objective] The relationship between the total petroleum hydrocarbons(TPH) and the total organic carbon(TOC) in soil of oil exploitation was studied.Method] The linear regression model and logarithmic fitting model were developed to simulate the concentrations of TPH and the contents of TOC in the soil by comparing the different regression models.Result] The determination coefficients(R2) for linear regression model and logarithmic fitting model were 0.715 and 0.874,respectively.The relative average deviations for the predictive values were 9.2% and 3.3% in a validation data set of 14,with the Nash-suttcliffe simulation efficiency coefficients(NSC) of 0.957 for the linear regression model and 0.959 for the logarithmic fitting model.Conclusion] The established models could provide reference for the application of spectroscopy and remote-sensing technology in the monitoring of petroleum hydrocarbons. |
