There are links between the effect of plant and the evaluation for bioavailability of heavy metals.In this paper the problem of bioavailability of heavy metals in polluted soil is reviewed and the correlation between the effects of plant and bioavailability are explained.At the same time,the applications of plant effects on the measuring and monitoring method of bioavailability are introduced in detail and some existing disadvantages are discussed.Consequently,measures with different plants can be taken to deal with different types of heavy metal polluted soil base on bioavailability.As an example,non-polluting agricultural products can be produced by planting heavy metal excluders in the low bioavailability soil,which proposes a new way for the safety of agricultural production.
