Comparative Study of Soil Macrofauna Community in Zuojia Nature Reserve Different Secondary Forest
Different secondary forest soil macrofauna at Shaw forest,Quercus mongollca&Betula davurica and Fraxinus rhynchophylla-Corylus heterophylla brush in Zuojia Nature Reserve was investigated. 2522 individuals of soil macrofauna were collected, belonging to 3 phyla,8 class,25 orders.

The diversity of soil macrofauna of Quercus mongollca&Betula davurica forest and Fraxinus rhynchophylla-Corylus heterophylla brush were similar. There was some difference in Shaw for-est. Simpson dominance index was high, while evenness,richness and diversity index was low.
