Research Progress on Accumulation and Phytoremediation of Heavy Metal Contaminated Soil by Woody Garden Plants

The situation of heavy metal pollution in urban soil in China is severe, which has seriously threatened human health, so it has been widely concerned.Woody garden plants have become an important research field of phytoremediation because of continuous remediation of heavy metal contaminated soil.Moreover, woody garden plants are the main body of urban greening construction, the vital unit of urban ecosystem, greening and beautifying the environment, especially will enter the food chain.In this study,the wood gardening plants used for remediation of heavy metal contaminated soil were reviewed,and the strengthening measures for remediation were discussed.This study focused on the enrichment effect of woody garden plants on various heavy metals,analyzed their tolerance and application potential of purifying soil heavy metal pollution,and forecasts the future development direction.
