Abstract A typical deciduous broadleaved forest in Langyashan Forest Park was studied and every tree in sample was surveyed.Regeneration characteristics and soil properties were investigated.The results showed that a total of 8 tree species(diameter at breast height≥3.0cm) which belonged to 7 families and 9 genii were recorded within 4 sampling plots.Aceraceae and Ulmaceae were dominant families in this forest type.The vertical structure of the forest was simple without obvious shrub and herb layers.In the arbor layer,Acer mono,Zelkova chneideriana and Platycarya strobilacea were the dominant tree species with absolute dominance.Tree species diversity was relatively low in this deciduous broadleaved forest.The characteristics of soils under this forest demonstrated that the concentrations of organic matter,available P and K were relatively high with a high EC and weak acidity.However,the soil depth in sites was shallow with a high content of rock fragments,which could be the major control for the low tree species diversity.TN、pH(H2O) and available N are the mostly factors affecting on the growth of tree in different population structures.This results would provide a scientific base for Langyashan forest regeneration and sustainable forest management.
