Taking Quercus acutissima -Cerasus -Robinia pseudoacacia mixed forest (MYC), Quercus acutissima -Pinus thunbergii -Acer mono mixed forest (MHW), Quercus acutissima -Pinus thunbergii -Cotinus coggygria mixed forest (MHH), and Quercus acutissima -Pinus thunbergii -Ailanthus altissima mixed forest (MHC) grown in the burned area of Weihai as research object, soil properties and species diversity were surveyed under four different afforestation patterns with naturally updated woodland (CK) as the control. The effects of different afforestation modes on soil remediation and the status of subforest vegetation renewal were analyzed. The results showed that:(1) MHH had the lowest soil bulk density in 0-40 cm soil layer, the best soil aeration performance, and the best soil water retention. MHC was the second and MYC the worst. All of these three were different significantly from CK (P<0.05); (2) The soil organic carbon, carbon nitrogen ratio (C/N), total phosphorus, total potassium and available potassium contents in MHH were the highest in 0-40 cm soil layer. MHC had the highest total nitrogen and available phosphorus contents in 0-40 cm soil layer. There was no significant difference in soil organic carbon, carbon/nitrogen ratio (C/N), total phosphorus, total potassium and CK between MYC and MHW (P<0.05). (3) MHH's Margalef index, Shannon-Wiener index, Simpson index and Pielou index were relatively higher; (4) After comprehensive analysis, it could be concluded that MHH had the best soil remediation effect on moderately burned land, and the regeneration rate of understory vegetation was the fastest, followed by MHC. MYC and MHW could improve soil physical properties obviously, but had no obvious effect on soil nutrients and understory plant regeneration.
