摘要
The ecological series of soil animals under the broad-leaved and pine mix ed forest in Darlidai Mountain was studied.Seven sample plots were selected according to different altitude gradients,which belong to dif ferent vegeta-tion types.By investigating and analyzing soil animals in every sample p lot it is found that there are 45group s and 1956individuals,which are involved in 3phylums,7classes,16orders,respectively.The altitude is a key factor which af-fects ecological series of soil anim als.Both the groups and individuals of soil animals increase with altitu de increasing under certain conditions,which con trastes with ordinary cases,resulting from special micro-climate in studied area.The groups and individuls of soil animals are the most under the broad-leaved and pine forest on the top of the mount ain,and the least under Picea-Abies forest in the foot of the mountain.

Seven sample plots were selected according to differentaltitude gradients, which belong to different vegetation types. By investigating and analyzing soilanimals in every sample plot it is found that there are 45 groups and 1956 individuals, which areinvolved in 3 phylums, 7 classes, 16 orders, respectively. The altitude is a key factor whichaffects ecological series of soil animals. Both the groups and individuals of soil animals increasewith altitude increasing under certain conditions, which contrastes with ordinary cases, resultingfrom special micro-climate in studied area. The groups and individuls of soil animals are the mostunder the broad-leaved and pine forest on the top of the mountain, and the least under Picea-Abiesforest in the foot of the mountain.
