In order to understand the dynamic change of soil chemical characteristics along with the succession stages for supporting forest restoration,the soil chemical characteristics in different succession stages were compared and analyzed.The results indicated that with the progress of succession,pH value,available P,and total K showed a decreasing trend while organic matters,total P,total N,alkaline hydrolytic N,and available K showed a trend of increase.The correlation analysis indicated that there was an significant correlation between soil chemical characteristics such as total N,alkaline hydrolytic N,available P and organic matters of different horizon in different succession stages.The correlation analysis somehow signified the main source of soil N and P was organic matters.During the forest restoration process,forest litters should be protected so as to increase soil organic matter and improve soil fertilization.
