Structural Characteristics of Soil Animal Community in Subalpine Picea aspoerata Plantation in Western Sichuan

HUANG Yu-mei et al (Dujiangyan Campus of Sichuan Agricultural University,Dujiangyan,Sichuan 611830)  
[Objective] The study aimed to understand deeply the ecology dynamics in the process of subalpine degraded forest ecosystem restoration and reconstruction in western Sichuan.[Method] The soil animal community in artificially planted Picea aspoerata pure plantation and artificial natural mixed plantation after cutting was studied in forest sample land in Bipenggou in Lixian County in 2007.[Result] In subalpine coniferous forest in western Sichuan,the Nematoda,Acarina and Collembola were the dominant groups of soil animal community and Diplopoda,Harpacticoida,Rotatoria,Enchytraeidae and Diptera(larva) were the frequent groups.The vertical distribution of soil animal community in ubalpine coniferous forest in western Sichuan still had surface accumulation,but had the tend of adown moving.Group number and DG(Density-groups) index of soil fauna in P.aspoerata pure plantation was lower than that of the mixed plantation,but without significant difference.[Conclusion] the degradation of P.aspoerata pure plantation was not severe.The biodiversity of soil organisms in its ecosystem would be enhanced through the regulation of the composition and structure of the vegetation.
