Characteristics of soil macroaggregates under typical forests in Pangquangou Nature Reserve

The content and stability of soil macroaggregates in 0-20 cm soil layer were studied for four typical forests (the coniferous and broad-leaved mixed forest (by the composition of Picea meyer, P. wilsonii, Larix principis-rupprechtii, Populus davidiana and Betula platyphlla), the broad-leaved forest of P. davidiana and B. platyphlla, the shrub of Hippophaer hamnoides and the Larix principis-rupprechtii forest) and an abandoned land (control) in Pangquangou Nature Reserve. This study provides certain scientific evidence for rational management of the forest resources of the reserve.
