In this study, the landscape plant Pteris crassipes was used as the experimental plant to study its remediation effect on soil lead pollution, and the possible remediation mechanism was explored by analyzing the changes of plant enzymes, soil enzyme activities and lead accumulation in Pteris crassipes. The results showed that chlorophyll, plant POD enzyme and plant CAT enzyme increased with the increase of lead concentration in the range of 0-500 mg·L^-1, while plant SOD enzyme showed a downward trend under lead stress, indicating that Pteris crassipes had a certain lead tolerance.Pteridoptera crassifolia can absorb high concentration of lead. The accumulation of lead in underground and above ground parts increases with the increase of soil lead concentration. The maximum concentration of lead in underground part is 82.578 mg·kg^-1, and that in aboveground part is 16.153 mg·kg^-1. The enrichment coefficients of underground part and aboveground part are all greater than 1, and the maximum concentration in underground part is 82.578 mg·kg^-1. The coefficient is 10.819, which indicates that Pteris crassipes has the ability to enrich heavy metals in soil in plants.The activities of sucrase, urease and phosphatase increased in low concentration of Pb (0-500 mg·L^-1) treatment compared with the control group, The results showed that rhizosphere microorganisms of Pteridoptera crassifolia could cooperate with plants to strengthen the remediation of heavy metal contaminated soil under the condition of low concentration of lead pollution.
