Method for estimating concentration change of heavy metal in soil along with time

The embodiment of the invention discloses a method for estimating the concentration change of heavy metal in soil along with time, and particularly relates to the field of soil heavy metal prediction.The form of the method for estimating the concentration change along with time is Ct=C0-E, and E=lambda*C0*R*K*LS*G*P/z. A method for predicting heavy metals in soil by adopting the model comprises the following steps: obtaining parameters of an initial value of the heavy metals in the soil, regional altitude, soil granularity and organic carbon TOC content through experimentsand inquiry; arranging the parameters in an excel table in sequence; carrying out programming on Matlab software to program an estimation method formula of the concentration change along with time; automatically reading and calculating parameter data in the excel table through the Matlab software with a programmed program; and finally, inputting a prediction age limit, operating to obtain a result, comparing the obtained result with a measur
