Abstract

Abstract:

Investigation on soil fauna was carried out in forest gap and under forest canopy of Cryptomeria fortune artificial stands. A total of 60 orders soil fauna, belonging to 10 phyla and 25 classes, were collected, and average density was 1.89×10⁴ ind./m². The group number of soil fauna in forest gap was higher than that under forest canopy, and both decreased when the soil layers increased. Densities in forest gap and under forest canopy were found to be significantly different in 0~5 cm layer (p<0.05). The guilds of soil fauna in forest gap and under forest canopy were dominated by the omnivorous, and followed by the saprozoic. H', J, and DG index were higher in forest gap than under forest canopy, but C index was lower in forest gap than under forest canopy, which showed that forest gap had influences on distribution and diversity of soil fauna in Cryptomeria fortune artificial stands.

Key words: Cryptomeria fortune artificial stands, forest gap, soil fauna, community structure
