Abstract: The dynamic simulation method was used for the first time in the data analyzing on rice resistant ability under cold temperature. The simulation results showed that “the inherent frequency” or “period”, the period size of plant growing system, could be used as the quantitative index of measuring cold resistance when the measurements well matched cold resistant magnitude. There are three different types of the indices in the plant resistance. The Dynamic simulation models could show inertia resistance, impedient resistance and recovery resistance.Dynamic simulation models are to be set up in the different plant growing stages,so that the plant growing process can be predicted and controlled.

Key words: phytoremediation, heavy metals-contaminated soil, mechanism, siderophore-producing rhizobacteria.
