In different phases of development, vegetation systems in this region have changed from pioneer herbage species initially recovering in abandoned cropping lands ( bothriochloa ischemum, artenmisia giradii and stipa bungeana, artenmisia sacrorum, spodiopogen sibiricus and sophora flavecens, themeda japonica, and arundinella anomala ) to secondary shrubs ( hippophae rhamnoides, sophora viciifdia, and ostryopsis davidiana ), early forest community ( populus davidiana, betula platyphylla and platycladus orientalis with arbors or shrub assembling ), and finally liaotungesis community as the mature forest. in this study, soil profiles ( 0 - 5, 5 - 15, 15 - 25, 25 - 35, 35 - 50 cm soil layers ) were selected from typical vegetation systems representing for vegetation successions in the region
