Studies on the diversity of soil animals in Taishan Mountain

Abstract

Taishan Mountain has diverse habitats and abundant groups of soil animals. Five habitats, Platycladus orientalis forest, Pinus densiflora forest, Robinia pseudoacacia forest, Pinus tablaerormis forest and Grassland, were selected and the diversity of soil animals in different habitats in Mt. Taishan were investigated and studied in 1997-1999. Totally 52 groups of soil animals were found, belonging separately to 7 Phyla, 11 Classes, 25 Orders and 28 suborders or families. There exists remarkable difference in groups, quantity and diversity of soil animals among the five habitats. Grassland habitat was the highest and Pinus densiflora forest was the lowest in groups, quantities, Density-group index (DG) and Diversity index of comparing many communities (D/C) of soil animals. Shannon-Wiener's diversity index (H') for soil animals of different habitats was in order of Platycladus orientalis forest＞Pinus densiflora forest＞Pinus tablaerormis forests＞Grassland＞Robinia pseudoacacia forest, Pielou's equality index (J') was Plalycladus orientalis forest＞Pinus densiflora forest＞Grassland＞Pinus tablaerormis forest＞Robinia pseudoacacia forest, and Simposn's dominant index (C) was Grassland＞Robinia pseudoacacia forests＞Pinus tablaerormis forest＞Pinus densiflora forest＞Platyciadus orientalis forest. The H' index and J index of macro-soil animal all were larger than that of mid-small soil animal. Clustering analysis for five soil animal communities and ordination analysis for community structure by multidimensional scaling (MDS) were made and completely identical results were obtained. Soil animal communities of five habitats were divided into 3 groups.
