Method for predicting efficiency of repairing organic polluted soil by plant

The present invention discloses a method for predicting efficiency of repairing organic polluted soil by a plant. The method comprises the following steps: 1), determining an advantageous repair plant; 2), testing the advantageous repair plant for pollutant absorbing kinetics; and 3), according a ratio (a TF value) between a pollutant concentration in cauline leaves when the pollutant plant absorbs in balance, and a pollutant concentration in the roof to predict efficiency of the selected plant repairing organic polluted soil. According the method for predicting efficiency of repairing organic polluted soil by the plant, the advantageous repair plant are determined by a restriction-distribution plant absorption model, meanwhile the factors that influences the prediction of plant repair efficiency, such as pollutant properties, plant toxicity and plant species can be eliminated, so that a obtained prediction result is excellent in accuracy, and with strong practical application; and meanwhile, the prediction method of the present invention is simple in operation, and wide in applicable range, facilitating efficiency, economy, environmental friendliness of the soil organic pollution repair work.
