title: [Simulation and verification for model of phytoremediation on heavy metal contaminated sediment].
abstract: In order to obtain dynamic changes of uptake and translocation and accumulation amounts of heavy metal lead in contaminated sediments in plants over time, the dynamic process of uptake and accumulation of lead in plants were simulated by system dynamics mechanism model of plant uptake to lead. Verification test was conducted based on simulation model after gain mass of data through planting maize in heavy metal contaminated sediment by greenhouse cultivation. The results indicate that the results of uptake and the accumulation of lead by maize in experiments are consistent with the conclusions of theoretical simulation model. It is proved that the dynamics mechanism model of plant uptake to lead is reasonable and effective.
